摘要
永泰旗山滑坡是福建省少见的深层中型岩质滑坡之一,2010年"5.18"强降雨诱发,滑坡中后缘拉张裂缝发育,前缘出现剥落、掉块、鼓胀、小滑坡,出现较明显的滑动征兆,采取应急卸方减载11×10~4 m^3,对滑坡稳定性起了重要作用。为彻底消除滑坡隐患,对滑坡进行了详细勘察、监测以及施工图设计。文章基于旗山滑坡变形活动特征,采用抗滑桩联合预应力锚索支挡+削坡减载联合坡面防护+微型桩局部加固+截排水(地表及地下)综合治理方案,为福建省相关类型滑坡防治提供参考案例。
Qishan landslide in Yongtai County is one of deep medium-sized rock landslides rare in Fujian Province. May 18,2012 heavy rainfall induced landslide, tension fracture de- veloped in the trailing edge of landslide, and the leading edge occurred spalling , falling block, bulging, small landsliding, the landslide appeared obvious sliding signs. Taking e- mergency measures to unload 110,000 m3 , played an important role in the stability of the landslide. To completely eliminate landslide hazards, the landslide has been carried out a de- tailed survey, monitoring and construction design. Based on the deformation activities char- acteristics of Qishan landslide, a comprehensive treatment plan was used that included pres- tressed anchor anti-slide pile retaining, unloading joint slope protection, mieropile partial re- inforcement and integrated drainage （surface and underground）. This paper provide a refer- ence case for prevention of correlated type landslides in Fujian Province.
