挡土墙抗滑稳定分析中分项系数的确定与对比

Determination and contrast of partial factors in anti-slide stability of retaining wall

从可靠性原理出发，主要探讨了换算内摩擦角φ0的不同换算方法和土性参数的变异性对挡土墙抗滑稳定分析中分项系数的影响以及分项系数与安全系数、可靠指标的相互关系．此外，还对墙高和墙重的影响进行了简单探讨，并与现行规范的规定进行了对比．

According to the principle of reliability, influences of different method and coefficient of variation of soil's parameter to partial factors in anti-slide stability of retaining wallare disscussed. The interaction relationship of partial factor safety factor and reliability indexis studied at the same time. In addition, height and weight's influence of retaining wall issimple discussed, and the existing code is compared.
