When the tall rigid frames for boat lefting in the Three Gorges were being analysed, we discovered that the so—called method of single distribution of moments can be improved upon as well as a new method of stress determination, namely the method of mean 'stiffness. For the calculation of tall frames, it was found that by means of lhese two methods accurate or approximate results can be obtained quickly and with great ease.In the case of the improved version of single distribution of moment method, a correction coefficient for the stiffness λ is to be used (λ_(AB)=1—C_(AB) C_(BA) μ_(BA), SO λ_(AB)=1—1/4μ_(BA), when the ordinary carrying factor is 1/2 and λ_(AB)=1—μ_(AB), when the oridnary carrying over factor is-1, where μ_(BA) is the ordinary distributing coeffcient). Multiplying the stiffness by this correction coeffcicnt, a set of distributing factors are calculated ( the same as those obtained by T. Y. Lin ). At the same, time, the ordinary carrying over factors are multiplied by the reciprocal of the correction coeffcient (?)/λ, so that a set of new carrying over factors are obtained. In this waY the calculation of new carrying over factors is much simplifted, at the same time the process of single distribution is also much simplified.In the case of the method of mean stiffness, an unsymmetrical multi-—story singlespanned rigid frame is transformed into a symmetrical one by using the mean stiffness instead of those original ones the structure. In this way the frame can then be analysed by means of Shagin (?) basic members and a single distribution with constant shears is crrried out. After this with a few ( once or twice ) simple adjustments, highly accurate results are ensued. This method can also been used for non-symmetrical multi-story and multi-spanned rigid frames as well (?) Vierendecl girders, and will give results to any degree of aocuracy quickly.

在三峽升船机高排架的計算中,我們对力矩一次分配法进行了改进,并研究出一个平均剛度法,这两个方法无論用之于高排架的精確計算或近似計算都是比較簡单而迅速的。改进后的力矩一次分配法是利用剛度修正系数入(λ_(AB)=1—C_(AB)C_(BA)μ_(BA)’当普通傳递系数C是(?)时則λ_(AB)==1—1μ_(BA),当普通傳递系数是—1时则λ_(AB)=1—μ_(BA),式中μ_(BA)是普通分配系数)乘剛度后計算一套分配系数(和林同棪的相同)再利用同样的剛度修正系数的倒数1/λ乘普通傅递系数,即得修正傳递系数,这样就能使修正傳递的系数的計算很簡单而且一次分配的过程也很簡单。平均剛度法是将不对称单跨多层剛架用平均剛度的办法使轉化为对称,从而可利用Шагин基本构件进行无剪力一次分配,再进行次数不多的(1至2次)簡单修正,即可得相当精确的結果,这个方法也可用之于不对称多层多跨剛架和不对称的空腹剛架的计算,迅速得出我們需要的任意精確的结果。

Research in fluvial geomorphology in China during the past 30 years was mainly along the lines of valley geomorphology, channel geomorphology, estuaries and deltas. A great amount of systematic investigations has been carried out in the fields such as valley evolution history and features of Changjiang River(Yangtze River) and Huanghe River(Yellow River) and their relations with geology, climate, neotectonic movement, etc. Field evidence suggests that the course of Sanxia(the Three Gorges) of Changjiang were...

Research in fluvial geomorphology in China during the past 30 years was mainly along the lines of valley geomorphology, channel geomorphology, estuaries and deltas. A great amount of systematic investigations has been carried out in the fields such as valley evolution history and features of Changjiang River(Yangtze River) and Huanghe River(Yellow River) and their relations with geology, climate, neotectonic movement, etc. Field evidence suggests that the course of Sanxia(the Three Gorges) of Changjiang were formed as early as at the end of the Cretaceous, and then the Yangtze valley was sharply cut down from the uplifting Exi planation surface, and took shape of a series of deep gorges into limestone strata. Investigations have also found that the upper reach of Jinsha River near Dengke once flowed southeastward into Yalong River. Recently the study of river valley geomorphology of the Xizang Plateau reveals that Yaluzangbu River is an antecedent river and that the Daguaiwan gorge in the east of it is neither an elbow ot capture nor a tributary flowing westward to join the Indus as were formerly taken to be. Research into channel geomorphology developed somewhat later, but has made rapid progress. A grade separation system has been put forward for the classification of channel patterns, and attentions given to the dynamic characteristics of the formation and evolution of channel patterns by using C_v(variation factor of the peak discharge) and ρo/ρp(the ratio of incoming sediment concentration to the sediment carrying capacity in a channel) as indexes to indicate the stabilities of different channel patterns and the mutual transformations among them. By analyzing many rivers with heavy sediment concentration, a wandering index has been derived. Rivers having the value of greater than 5 are called shifting and less than 2 unshifting. In the middle and lower Changjiang, the latest research of meanders and relatively stable channel patterns has had some results. Observations and simulation experiments con the fluvial processes of the channels above and below reservoirs reveal that the channel of Huanghe below Sanmenxia Reservoir, after baving been washed by clear water, still remains shifting for a long time, and the headward silting end of Weihe channel above the reservoir stretches out or draws back within a certain limit. The investigations of deltas point out that since the Quaternary the mouth of Changjiang has been extending southeastward and that there exist imbricate fossil deltas under the water. As for the Huanghe delta, it is evident that since the diversion of the river course in 1855, a new delta with an area of 5,450 km~2 has been built up. Penetrating research has also been made on the geomorphological features and processes of the evolution of Qiantang River. Field survey discovers that the main source of Changjiang is Tuotuo River rising in Geladandong snowberg, and that of Huanghe is Kariqiu River originating in Geshigeya Mountain of the Bayankala Mountains.

三十年来我国河流地貌的研究主要为河谷地貌、河床演变和河口三角洲。其中,河谷地貌研究提出了长江三峡在白垩纪末已经形成,其后从鄂西期夷平面下切于石灰岩层内而形成一系列峡谷。发现金沙江上游在邓柯附近曾向东南流入雅砻江。论证了雅鲁藏布江横贯喜马拉雅山脉的为先成河,并非由于河流袭夺的结果。河床演变的研究提出了游荡指标>5为游荡,<2为非游荡。以C_v和ρ_o/ρ_p两值作为河型稳定和转化的指标。对三门峡、丹江口等水库上下游的河床演变进行了观测和模拟试验。研究了长江、黄河和珠江等三角洲的形成演变,提出了新的见解。经过实地考察发现长江的正源为沱沱河,发源于各拉丹冬雪山;黄河的正源为卡日曲,发源于巴颜喀拉山脉的各式各雅山。

The first thing in the stability analysis of underground opennings is the determination of the deformation failure-movement type of rock masses. In this paper five main types of deformation failure-movement has been mentioned, according to different combinations of the four rock mechanics factors. Thus, primary appreciation of stability and selection of mechanical model for the rock mass can be made in design work. Some methods of stability analysis for rock mass composed of rock blocks has been discussed, referring to the underground power station of The Three Gorges project as an example. Planes of discontinuity should be simplified according to their relative size to the dimensions of the cavity. The influence of the stress component along the axis of the cavity on the stability of rock blocks has been emphasized. In those cases when finite element method in three-dimensions can not be used, calculations may be carried out by two-dimensional finite element method in combination with the method of the whole space projection on equatorial plane. When the orientation of the axis of cavity is to be determined, not only the direction of the maximum in-situ stress but also the azimuth of planes of discontinuity should be considered.

地下厂房稳定分析首先要确定围岩变形破坏运动类型。本文按照四种岩石力学条件从工程实践中归纳了五种变形破坏运动类型,以便在设计阶段进行初步判断和选择岩体力学模型,并以三峡工程地下厂房为实例,着重研究了块体结构的围岩稳定分析方法。在建立围岩力学模型时,要结合地下洞室的尺寸处理不同规模的不连续面。三个方向的应力对块体稳定性的响影同样重要,在没有条件使用三维有限单元法时,可用全空间赤平投影法与二维有限单元法结合计算。研究结果表明,在设计地下洞室方向时,不仅要考虑初始应力的方位,同时还应考虑软弱结构面的方向。
