英语翻译
A complex basis for the strength and stability of the lightweight shape of the gravity dam was developed for the design under consideration.The stress-strain state for a basic and a special loading combination were computed independently by the All-Union Lenin Order S.Ya.Zhuk Scientific-Research Institute for Design and Exploration,the B.E.Vedeneev All-Union Scientific-Research Institute of Hydraulic Engineering,and the Hydromechanics Institute of the Academy of Sciences of the Ukrainian SStL while shear-resistance and overturning computations
were performed by the All-Union Lenin Order S.Ya.Zhuk Scientific-Research Institute for Design and Exploration.We tested 71 dam models,including three models built to a 1 :125 scale at the Scientific-Research Department of the All-Union Lenin Order S.Ya.Zhuk Scientific-Research Institute for D esign and Exploration and 43 models built to a 1 :200 scale at the V.V.Kuybyshev Moscow,Order of Red Labor Banner Civil Engineering Institute to study the stress-strain state under a basic loading combination with the model brought to failure by increasing the horizontal loads to determine the ultimate stability of the dam and its components.
Seventeen 1 :100-scale models and three 1 :50-scale models were tested at the B.E.Vedeneev All-Union
Scientific-Research Institute of Hydraulic Engineering to investigate the stability of the compression zone by
bringing the models to failure with a simultaneous increase in horizontal and vertical loads to determine the ultimate strength of the material in the compression zone; finally,four 1 :100-scale models and 1 :200-scale models were tested by he Scientific-Research Department of the All-Union Lenin Order S.Ya.Zhuk Scientific-Research Institute for Design and Exploration to investigate the earthquake resistance of the dam.
The basic results of the stress state computations for the dam with a basic loading combination are presented in Table 3.
Normal compressive stresses do not exceed 40 kg/cm 2 and principal compressive stresses 60 kg/cm z at the downstream face.In the absence of cracking in the upstream face,normal tensile stresses do not exceed 5-7 kg/cm2; this is comparable to the computed tensile strength of the construction joints which was attained during construction of the Toktogul hydroelectric plant [8].In cases where cracking develops along several construction joints,the upstream face is virtually relieved of tensile stresses and a 10-15% increase in compressive stresses occurs on the downstream face.Similar results were also obtained during the model studies.
The computations and model studies indicate that the opening of cracks to a depth of,at most,1/4 the height of the cross section of the dam can be expected during the service period.The width of the opening may vary from 0.1 mm where crack spacings are of the order of 5 m to 0.3 mm where they are spaced 20 meters apart.

基本结果的应力状态计算大坝基本负荷组合列于表3 .
正常的压应力不超过40公斤/厘米2和主压应力60公斤/厘米ž在下游的脸.在没有裂缝在上游面,普通拉应力不超过5-7 kg/cm2 ;这是可比的计算抗拉强度施工缝是实现施工过程中的托克托古尔水力发电厂[ 8 ] .龟裂的情况下,开发沿线几个施工缝,上游面对几乎是解除拉伸应力和10-15 %的增长压应力发生在下游face.Similar结果还获得了在该模型的研究.
模型的计算和研究表明,开放的裂缝的深度,在大多数,1 / 4的高度截面大坝在可预期的服务期.宽度的开放可能会有所不同从0.1毫米间距的情况下打击的命令,5米至0.3毫米,他们的间距20米远.
