地面建筑物采空区的勘探及治理

Exploration and Governance of Gob of Ground Buildings

利用地球物理勘探,采用地空协同时频域电磁探测方法,根据地下空洞特征、现场地形条件及拟建工程情况,通过分析收集的资料和工程地质调查初步结果,根据物探结合钻探相互印证方法,确定地下空洞的特征和范围。对治理区域的采空区、巷道、裂隙进行充填和固结,提高了场地地基的整体性和稳定性,治理场地稳定性等级为稳定,效果良好。

The study does geophysical exploration, adopts ground-air cooperative time-frequency domain electromagnetic detection method, analyzes the materials and preliminary results of engineering geological survey according to underground cavity characteristics, site topographic conditions and proposed project situation, and determines the characteristics and scope of underground cavity according to the mutual corroboration of geophysical and drilling prospecting. The filling and concretion of the goaf, roadway and fracture of governance areas improves the integrality and stability of site foundation, with the stable grade and good effect.
