高边坡抗滑桩加固效果与监测成果分析

Monitoring and Analysis of the Slope Instability Mitigated by Bored Piles

抗滑桩是边坡加固的重要手段之一,已得到广泛应用。对广西某电厂加固后的抗滑桩进行监测,包括抗滑桩深层水平位移监测、桩墙钢筋应力监测和预应力锚索监测,监测结果表明,加固后的抗滑桩在施工期内变化稳定,加固效果明显,保证了工程顺利施工。

The anti--landslide pile is one of the important and widely used methods in the landslide mitigations. This paper doc- uments the instrumentation results of bored piles used as the slope stability elements in a high slope stability of a power plant construction in Guangxi Province. The horizontal deformation at different depths, rebar stress in piles, and the stress in the pre-stresses anchors are monitored. The results indicate that the bored pile is effective in mitigating the potential instability.
