| 摘 要： | 滑坡是重庆市重点地质灾害之一 .在地质勘探的基础上 ,采用传递系数法计算滑坡推力 ,从而确定滑坡体和滑塌体的稳定性 .计算分析表明 ,在天然 (枯季 )状态下 (荷载组合I) ,新滑坡稳定性系数为 1 0 5～ 1 4 2 ,滑塌体的稳定性系数为 1 0 5～ 1 31 ,其中大部分剖面稳定性系数在 1 0 5～ 1 0 7之间 ,滑坡呈基本稳定状态 ;在饱水状态 (洪季 )、不考虑土体抗剪强度降低的影响下 (所取土样已为饱水状态 ) ,仅考虑土体总重量增大及河水涨落产生的动水作用时 (荷载组合II) ,新滑坡稳定性系数为 0 97～ 1 0 3,滑塌体稳定性系数为 0 96～ 1 0 6 ,呈较稳定状态 ;在考虑地震力作用时 (荷载组合III) ,新滑坡稳定性系数 0 90～ 1 0 0 (仅 1 0 1 0′剖面为 1 2 4 ) ,滑塌体稳定性系数为 0 90～0 97,呈不稳定状态

| Abstract: | The landslide is one of the worst geological disasters in Chongqing. Based on the geological survey, the stability of landslide and slump were determined in terms of slip force calculated by using transfer coefficient method. The results show that: ① in combination I (dry season), the new landslide stability coefficient is 1 05～1 42, the slump is 1 05～1 31, most of them are between 1 05 and 1 07, which is in stable status; ② in combination II (soil moisture is saturated in wet seasons), without concerning the induce of anti shear stress and only concerning increasing weight of soil body and interaction between raise and drop of water level in the mean time, the new landslide stability coefficient is 0 97～1 03, the slump is 0 96～1 06, which are between unstable and stable status; ③ in combination III (the earthquake factor is considered ), the new landslide stability coefficient is 0 90～1 00, the slump is 0 90～0 97, which are in unstable status. |
