锚拉抗滑桩及锚喷技术联合应用于快速滑动的滑坡防护加固工程

Combination of Anchoring-drawing Anti-slide Pile and Anchor Spray Technology Applied in Rapid Sliding Landslide Protective Strengthening

摘要:

以桂林—阳朔高速公路K2542+750～810上边坡滑坡防护治理工程为例，介绍了锚拉抗滑桩及锚喷技术联合应用于治理快速滑动的滑坡的应用情况。滑坡体主要由断层破碎带岩土组成，具有地质构造复杂、岩石破碎、残坡积土孔隙大、雨季地下水丰富、滑坡体岩石成分复杂、力学性能差异大、正处于快速滑移阶段等特点；在滑坡防护加固工程的设计和施工中采用该技术方法等综合措施，解决了突出的问题，并取得了良好的经济效益和社会效果。

Abstract:

With an engineering case of side slope sliding protective control for K2542 750～810 in Guilin-Yangshuo expressway, the paper introduces the application of the combination of anchoring-drawing anti-slide pile and anchor spray technology for rapid sliding landslide protective strengthening. The landslide is mainly composed of rocks and soil of fault fracture zone with complex geological structure, rock breaking, large rock pores, rich groundwater in rainy season, complex composition of slope rocks and large difference in mechanical properties; what was more, it was in the rapid sliding stage, this technical methods and some comprehensive measures were taken in the engineering design and the construction with good effects.

Key words:anchoring-drawing anti-slide pile; anchor spray; rapid sliding landslide; fault fracture zone; protective strengthening
