The Yangtze Valley Hydro-electric Scheme is an abnormally tremendous engineering project in the world. The trestle bridges required for concreting the dam only are of abnormal size for instauce. The main trestle bridge has to carry five lines of standard gauge railway track and two tracks for loading about 30 huge concreting cranes of about 700 tons in dead weight each. The bridge required for the first stage of work is about 90m.in height,and later on the whole flooring system of the bridge has to be lifted...

The Yangtze Valley Hydro-electric Scheme is an abnormally tremendous engineering project in the world. The trestle bridges required for concreting the dam only are of abnormal size for instauce. The main trestle bridge has to carry five lines of standard gauge railway track and two tracks for loading about 30 huge concreting cranes of about 700 tons in dead weight each. The bridge required for the first stage of work is about 90m.in height,and later on the whole flooring system of the bridge has to be lifted twice, each time being lifted 35m. in height. In addition, the bridge must be constructed and lifted with in the given comparatively short period of time. In this paper, some proposals for the preliminary design of the trestle bridge are presented. In the design, the super-structure contains a series of welded steel plate girders. The main girders are 24 meters span all-welded steel Plate girders of the standard railway bridge design. Two alternative designs of the trestles are proposed for comparison,one being composed of reinforced concrete tube posts of 2.0 meter diameter,similar to those used in the sub-structure of the famous Yangtze Bridge in Wuhan, the other being of steel structure. Necessary figures of the results of the design are given including the quantity of materials, the time and procedure of erection,etc. On account of economyof steel the design of R.C. trestles is suggested to be adapted in comparison with the steel structure.

用电阻丝应变片电测应力的技术近年来得到很快的发展,对于许多应力测定问题都得到广泛的应用,但是仍有一些实际应用中的问题还没有得到完善的解决。考虑到南京长江大桥管柱应力测定的要求,我们必须解决在混凝土内装置电阻丝应变片能够抵抗潮气和为时36~48小时的80℃蒸汽养护的侵蚀,而且能够经常在深水中正常使用,期限长达三、四个月之久等等问题。为此,我们对各种不同方法曾在郑州黄河桥工地和铁道科学研究院实验室内进行了试验研究。作者所提出的某些方法在试验中证明得到成功。本文就是我们所进行的这些工作的报道。

In this paper, the author summarizes first the existing state and some problems on the calculation of crack width and deflection of R. C. beams. Secondly, with the average crack widths calculated by means of the formula recommended in Russion Code, the author compares the max. crack widths measured from some foreign tests, and according to the principles of statistics, gives a discussion about the coefficient for determining the max. crack width suggested by Chinese Code (project). Having pointed out the unreasonable conditions of the summation formula for calculating the crack width of beams subjected to partial long-time loads in Russian Code, the author suggests two synthetic formulas for the calculation of crack width and deflection, by which we can not only eliminate those unreasonable conditions, but also make the calculation much simpler. For the value of ν in the coefficient γ' which is used to calculate the stiffness of doubly reinforced beams, the author suggests a new recommendation and makes a comparison with the experimental deflections to prove that this recommedation is reasonable. Finally, for the corrected coefficients of the moments at supoart to consider the redistribution of stresses in the continuous beams due to cracking, the author also makes a new recommendation, and carries out comparative computation with some measured deflections from tests. At the same time, for some particular loading conditions which may take place frequently in practice, the author prepares curves of deflection coefficients in order to simplify the calculation of deflection of continuous beams in practical designs.

在本文中,首先对国际上关于鋼筋砼受弯构件的裂縫和变形計算的現阶情况和存在的一些問題作了概述. 其次利用苏联規范中的公式計算的平均裂縫寬度与国外的某些試驗中量得的最大裂縫寬度比較,根据統計原理,来討論我国規范草案中建議确定最大裂縫寬度的系数。作者还指出苏联規范中对部分长期載时計算裂縫寬度的总和公式的不合理情况,因此对裂縫計算,也包括变形計算,提出了綜合公式,这不但可消除这些不合理情况,同时計算也簡单些。对双筋梁刚度計算中系数γ′內的ν值,作者提出了新的建議,并和实驗挠度进行比較,証明这一建議的合理性。最后对考虑連續梁由于裂縫所引起的內力重分布时支座弯矩修正系数提出了建議,并和一些实驗結果进行了比較計算,同时繪制了几种常遇到的荷載情况下的挠度系数曲綫以簡化在实际工作中連梁挠度的計算。

This paper describes prestressed reinforced concrete truss type arch bridges. which were developed on the base of the ordinary reinfrced concrete truss type arch bridges. When the later is prestressed in some parts, the ability to resist crack is raised, the structural monolith is increased, the structural pattern is simplified, and thus good effects will be achieved in the engineening practices.
