中文摘要：

筏板式格构-锚杆-锚索复合抗滑支挡结构是治理土质滑坡的一种新型有效的技术。该结构由筏板式格构、膨胀型锚杆和预应力锚索组成,结合了普通格构和筏板基础的综合功能。通过建立简化结构计算模型,确定了结构中所需锚杆以及锚索数量的计算方法。结合工程应用,针对大型松散堆积层滑坡—重庆市万州区清泉路滑坡,分析表明本文提出的新型结构的设计方法能够满足工程安全要求,该新型结构具有一定的工程适用性。

英文摘要：

Composite anti-sliding retaining structure of raft-type lattice beam—bolt—anchor cable is the new kind effective technique for soil landslide treatment. The composite anti-sliding retaining structure is composed of raft-type lattice beam,expandable bolt and pre-stressed anchor,combining the function of ordinary lattice beam and raft. By establishing a simplified structure calculation model,the method to decide needed numbers of bolt and anchor cable is also suggested. Combining with the engineering application,the analysis results of Qingquanlu landslide,situateded in Wanzhou of Chongqing city show that the related design method of th I new structure can meet the engineering requirements,the new structure has a certain engineering applicability.
