两种土石坝型应力和变形特性的比较分析
Comparison and analyses of stress and deformation characteristics for two kinds of earth-rock dams
【摘要】 结合某在建水库大坝的粘土直心墙和斜心墙两种坝型方案,分别在静力和地震力作用下对坝体在竣工期和运行期的变形、应力及坝体的稳定性进行了计算,从应力、变形和安全的角度对两种坝型的优劣进行了比较分析,得出了一些有益的结论,可以为类似工程及设计提供参考。
【Abstract】 With the outcomes of numerical analyses of characteristics of static and dynamic for a building reservoir dam,the advantages and disadvantages of vertical-core and inclined-core earth-rock dams are compared and analysed from the aspects of stress or deformation and security of dam;and some useful conclusions are drawn.These conclusions can be for reference in constructing some similar engineerings and the design。
