| 摘 要： | 以某水电站F3,F9断层上盘变形体为对象,开展了U形河段三面临空变形体稳定性分析。首先从变形体的形态特征和地质条件入手,对其形成机制和运动趋势进行了初步分析;其次,根据潜在的滑移趋势,选取了2个代表性剖面,采用有限元方法计算了代表性剖面在3种工况下的破坏区域,通过对比分析破坏面积发现变形体沿代表性剖面1方向的稳定性较好,而沿代表性剖面2的较差;最后,采用刚体极限平衡法(M-P)和有限元应力法对代表性剖面2进行抗滑稳定计算,结果表明,在各种工况下,变形体抗滑稳定均能满足工程要求。通过研究F3,F9断层上盘变形体的稳定性,探讨了变形体稳定性分析的新思路,对类似工程具有一定的借鉴意义。 |

| Abstract: | Based on the upper plate deformation body of F3 and F9 faults in a hydropower station,stability analysis was made on the three-side hanging deformation body in a U-shape river reach.First,the forming mechanism and movement tendency was analyzed on the basis of morphology and geological conditions of the deformation body;then,according to the sliding trend,2 representative sections are selected and calculated by finite element method to determine their failure zones in 3 operation conditions.In comparison wi... |
