【摘要】 地下采矿活动引起覆岩移动、变形和破坏，其表现形式之一是地表浅部产生斑裂（或裂缝），对建筑物危害极大。本文研究了地表斑裂的物理场响应特征，通过电阻率法和地震法的观测试验，进行隐伏斑裂的实地探测，为建筑物加固和地基处理提供了可靠的技术保障更多还原

【Abstract】 mining-induced movement,deformation and failure of overlying strata may manifest themselves in the presence of surface cracks at shallow depth,posing great menace to surface buildings.The study of geophysical field respond charateristic of this cracks and their successful detection with resistivity and seismic methods provide a reliable technical for building reinforcement and foundation treatment.更多还原
