| 摘 要： | 基于可靠度理论,利用可靠度理论中的概率矩点估计法对延安市宝塔区卧虎山滑坡的稳定系数、可靠度和破坏概率进行了计算、分析。计算结果表明,基于可靠度理论滑坡稳定性计算能克服客观存在的土性参数的空间离散性、时间变异性,并把计算结果与传统稳定性计算结果进行了分析比较,证明了基于可靠度理论的滑坡稳定性计算方法的可靠性和可行性。

| Abstract: | It is by means of Rosenblueth method based on reliability theory according to calculate stability coefficient,reliability and failure probability of Wohushan landslide in Baota District in Yan-An.The calculation results show that stability calculation of the landslide based on reliability theory can overcome divergence in space and time variation of the soil parameters existing objectively.In addition,compared with traditional stability calculation methods,stability calculation of the landslide based on reliability theory is more reliable. |
