水压爆破在人工开挖抗滑桩中的应用

Application of Hydraulic Blasting in Artificial Excavation Slide-resistance Piles

抗滑桩由于其显著的抗滑作用,近年来在滑坡地质灾害治理工程中得到广泛的采用。由于产生滑坡地质灾害的地层及水文条件的复杂性,给抗滑桩的成孔施工带来了极大的困难,特别是在遇到含水、坚硬漂石层中施工时,施工安全、质量、进度、成本都会受到严重的影响。特对“康定城区白土坎滑坡整治二期工程”施工中遇到的含水、坚硬漂石土所采取的水压爆破进行总结分析。

Slide-resistance piles have been widely applied in landslide geohazard controlling engineering in recent years because of their remarkable slide-resistance action. The complexity of the strata arising landslide geohazard and hydrologic conditions have brought about a tremendous difficulty in the hole completion construction of slide-resistance piles, especially the safety quality, progress and cost of construction will get a serious influence. This paper summarizes and analyzes the adopted hydraulic blasting technique for the above-mentioned strata in the construction of ＂ The Second Phase Project of Baitukan Landslide Renovation in Kangding City Proper＂.
