摘要
通过对忠县至万州高速公路K38路基边坡抗滑桩支挡失效过程中桩基的变形监测及桩基完整性检测结果进行深入剖析,得出抗滑桩破坏类型及失效深层原因。基于施工过程及桩基变形规律的分析,得出边坡排水设施施工不及时,致使雨季雨水侵入边坡,从而导致滑坡推力增大是边坡治理失效的主要原因,并以此指导边坡2次治理,不留后患。
Based on deep analysis for the results of deformation monitoring and integrity detection of pile foundation during anti-slide pile support slope on K38 roadbed of Zhong County-Wanzhou Expressway,this paper obtains destruction types of anti-slide piles and deep reasons of failure. Based on analysis for construction process and deformation rules of pile foundation,the paper draws a conclusion that increase of landslide thrust,which was caused by invasion of rainwater into the slope in rainy season since drainage facilities on the slope are not constructed in time,is the main reason. This paper also suggests conducting a follow-up treatment of the slope to prevent future troubles.
