The arch belly gravity dam is a new type of dam. Its upstream face is inclined and it has a belly arch within. The stress distribution of the dam section is comparatively uniform so that the strength of materials can be filly utilized; the vertical stress at the heel of the dam is comparative high so that the capability of the dam to sustain extraordinary overloading is high. .Comparing with ordinary gravity dam, its stress condition is greatly improved. In order to search for the best profile of new type of dam, stress experiments of more than twenty profiles of the dam section of different dimension have been performed by photoelastic frozen method. Through balance check of forces and repeated tests of recommened profiles, it has been proved that the results of the experimentals are believable. The stress condition of several profiles is also experimented with the net method of gelatin models. The stresses are also computed by structure theory with the profile assumed as a hingeless arch. The stresses obtained by the above three methods are approximate. Based upon the results of stress experiments, the effect of the change of dimension of the profile on the stress distribution has been studied. It is considered that the rule to determine the dimension is as follow: The slope of upstream face would be 1: 0. 2-1: 0. 4, and that of the downstream face 1:0. 75-1: 0. 9; the belly arch would be made elliptical with its major axis slightly inclined toward upstream; the arch would be -25--~35% as high as the dam; the upstream leg would be thicker than the downstream leg, so that the center of the gravity of the section would be slightly shifted to the upstream. If the arch belly are used as powerhouse of hydroelectric plant, the width of the draft tube would be equal to or less than 30% of the dam block. The results of stress experiments of the finally recommended profiles have shown that the stresses in the dam section are principal compressive, the stress distribution in the dam section is uniform, and the stress at the heel of the dam is higher. Take profile 1-Ⅷ as an example, compressive stresses occur in the whole section, except that at a few points tensile stresses of no more than 4 kr/cm2 are developed. The ratio of maxinum and mininum stresses in the section is less than 2. The vertical compressive stress at the heel of the dam is, greater than two times the head at the same point, so that the dam has greater capability to resist the overloading. It can be seen that the arch belly gravity dam is a noteworthy new type of dam

腹拱式重力坝是一种新坝型,坝上游面倾斜,坝内设有腹拱。坝体断面的应力分布比较均匀,坝体材料得到充分的利用,上游坝趾的垂直应力较高,坝体承受特殊超载的能力较大,比较一般砼重力坝的应力状态有了很大改善。为了寻找这种新坝型的最好轮廓剖面,利用偏光弹性力学的冻结应力方法,做了廿多组不同轮廓尺寸的坝体剖面的应力试验,经过平衡校核,对于推荐的剖面还进行了重复试验,认为试验结果是可信的。试验中个别方案还采用了软胶纲格法试验;并简化成无铰拱,用结构力学的方法进行了近似的应力计算。三种不同方法所得的应力情形是接近的。根据不同轮廓尺寸剖面应力试验的结果,分析了各种轮廓尺寸的变化对坝体应力分布的影响。初步认为确定坝体轮廓尺寸的规则如下:坝体上游边坡宜为:1∶0.2-1∶0.4,下游边坡宜为1∶0.75-1∶0.9;腹拱宜做成略向上游倾斜的椭圆形;拱高宜为坝高的25-35%;上游腿应比下游腿略厚,以使重心偏向上游;设置坝内电厂时尾水管的宽度宜等于或小于坝段宽的30%。最后推荐方案的应力试验成果,坝体基本上全部为压应力,坝体断面的应力分布均匀,上游坝趾的压应力较高。以1-Ⅷ号方案为例,坝内只个别点出现了最大为4公斤/厘米2的拉应力,?

The electrophoretie mobility(EPM)of fetal liver cells(FLC)of LACAmouse is higher than that of adult bone marrow cells(ABMC)(P<0.01).Treatment with neuraminidase(NA)led to the decrease of EPM of these cellsbut the decrement of FLC(32%)was greater than that of ABMC(24%).Maybethere were more sialic acid residues susceptible to NA on the surface of FLC.Treatment with NA reduced the numbers of spleen colonies in the lethally irrad-iated syngenie recipient mice after transfusion of either FLC or ABMC,whichmight result from depressed seeding efficiency of NA-treated CFU-S.CFU-S of FLCshowed greater capability of self-renewal than that of ABMC.After treatment withNA,the self-renewal ability of CFU-S of routine fetal liver and adult bonemarrow appeared to change in parallel with EPM of FLC and ABMC.Thesignificance of these changes was discussed.

本文显示小鼠胎肝细胞电泳率(EPM)比成年骨髓细胞高。用神经氨酸酶处理以后,二者 EPM 均下降,但胎肝细胞下降幅度较大。同时胎肝 CFU-S 与成年骨髓 CFU-S 的自我更新能力在用神经氨酸酶处理前后表现出与 EPM 平行的变化。文中讨论了这种关系的意义。
