中文摘要: |
位于高地震烈度区的卡拉贝利水利枢纽工程,其联合进水口的高大塔群坐落在软岩之上,塔基形成有坡度的建基面,侧向抗滑问题值得关注。塔基侧向抗滑稳定需考虑多个建筑物、构筑物之间的荷载传递,给设计计算带来困难。本文借鉴重力坝深层抗滑稳定分析的“等安全系数法”原理,编制程序,计算得出抗滑稳定安全系数,为解决塔群地基侧向抗滑的设计计算提供了一种途径,对类似工程的设计有借鉴意义。对影响抗滑稳定安全系数的河床滑出块底面倾角、岩-砼摩擦系数进行了敏感性分析。 |
英文摘要: |
The intake towers of Kalabeili Water Project is built on soft rock in high seismic intensity area, with a slope base. So, the base lateral sliding is concerned. It is difficult to calculate lateral sliding safety factor beacause the load transfer between 7 blocks is complicated. In this paper,a solution approach is pro-posed,referencing the equal safety factor method principle of gravity dam deep stability analysis,and later-al sliding safety factors of multi-load cases are calculated with computer program. This approach offers a valuable reference for similar project design. The base sliding stability sensitivities of riverbed block bottom surface inclination angle and rock-concrete friction coefficient are analysed. |
