建筑场地老采空区综合勘察及处理方法

Comprehensive survey and treatment methods for old goafs in construction sites

针对老采空区不良地质基础导致的建筑下沉问题,旨在勘查前期能够对采空区的范围进行准确的探测和划定,以及为地基处理措施的选择提供依据。探讨了采用物探勘测,钻探验证的方法对目标区域采空区进行综合地质勘探与研究,并提出了相应地基处理措施。

In view of the problem of building subsidence caused by bad geological foundation in old goaf area,the goaf scope must be accurately detected and delimited in the early stage of exploration,and to provide basis for the selection of foundation treatment measures.By using the method of geophysical survey and drilling verification,the comprehensive geological exploration on the goaf in the target area was carried out,and corresponding foundation treatment measures were proposed.
