摘要
土质边坡稳定安全系数的计算值主要与采用的简化计算方法和土工参数有关。采用正交试验法计算分析了不同的计算方法、材料参数、水位及其相关荷载、地震作用等对边坡安全系数计算值的影响,进而对设计中的计算方法和材料参数提出了一些有益的建议,并提出了在工程运行管理中应尽量避免低水位或水位骤降情况的意见,为土石坝类工程的设计与运行管理提供了重要参考。
The calculated data of safety coefficient of soil slope stability is related to the simplification method and geo-technical parameters. The paper adopts orthogonal test to analyze the influences of different calculation methods, material parameters, water levels and related load and earthquake on the calculated data of slope safety coefficient. The paper also proposes some beneficial suggestions for the calculation methods and material parameters in the design, opinions of avoiding operation at low water level and abrupt fall of water level. Therefore, the study can provide reference for soil and rock dam design, operation and management.
