【摘要】 以官地水电站重力坝典型坝段为研究对象,对其深层抗滑稳定采用多滑面抗滑稳定和双滑动面抗滑稳定两种方法进行分析,对比两种方法的合理性。结果显示,多滑面抗滑稳定分析方法在结构复杂、错动带比较发育的坝基中的成果较为合理和真实。更多还原

【Abstract】 The stability of gravity dams against deep sliding is the key problem of the dam safety. While,two different analysis methods are available,i. e. the multiple sliding surface method and the dual sliding surface method. A comparison on these two methods are then carried out with a stability analysis on the Guandi Gravity Dam. Results show that the multiple sliding surface method is relatively more reasonable in the case that complex structures and fault zones are developed in the dam foundation.更多还原
