预应力锚索格构梁与锚索抗滑桩在滑坡治理中的比选分析

Study on Comparison between Prestressed Anchor Cable Lattice Beam and Anchor Cable Anti-sliding Pile in landslide Control

以桂林某古滑坡治理工程为例,在治理设计中采用了预应力锚索格构梁和预应力锚索抗滑桩两种支护方案,以这两种支护方案进行有限元数值模拟,从滑坡的位移及稳定系数对模拟的结果进行了分析,并结合支护方案的施工难易程度、工程经济、对环境的影响等因素进行了综合对比分析,确定最优方案为锚索抗滑桩。可为同类工程提供借鉴。

Taking an ancient landslide control engineering in Guilin as an example, two supporting schemes, prestressed anchor cable lattice beam and prestressed anchor cable anti-sliding pile, were designed for landslide control, in respect of which FEM numerical simulation was conducted, then the results were analyzed from the aspects of the landslide displacement and stability factor. Combining with the construction difficulties, project cost and effects on the environment, the supporting schemes were compared and analyzed comprehensively, as a result, the optimal design was confirmed to be anchor cable anti-sliding pile. It may be referred to by similar engineering.
