| 摘 要： | 建于中细砂层上的多层教学楼,下伏灰岩岩溶发育,地下水活动剧烈,使用7 a后,室内外地面出现陷坑,楼两端也过量沉降.文中介绍了为抢险而进行的工程物探、钻探补充勘察,进而开展地基加固治理设计、施工及沉降变形观测,及时恢复了教学楼的使用,为既有建筑物在岩溶地质灾害发育区的勘察、治理设计及施工积累了工程经验。

| Abstract: | The multi-layered building which is based on fine sand strata with limestone underlying,where karst has been developed,and the groundwater is active fiercely.After 7 years,the building foundation inside and outside appeared pits and the the building also subsided excessively.This paper introduced the project physical prospecting and drilling supplement survey which was for the emergency,and described carrying out the ground stabilization control design,construction and observation of subsidence distortion.This successful example provided experience for reconnaissance in karst geology disaster growth area reconnaissance as well as the control design and construction |
