%X 蓝山县湘源小学综合楼场地出现地面塌陷现象，为了查明产生塌陷的原因及存在的隐患，为此采用高密度电法对蓝山县湘源小学综合楼房屋地基进行物探测量，探测塌陷区的赋存状态以及场地内是否存在土洞、岩溶等不良地质现象。方法是在场地内布设了3条高密度电法测线，经探测查明了塌陷是由于场地范围内普遍分布有低阻含水软弱不良地层而产生的。高密度电法在该区的应用有效地探明了塌陷区赋存状态和范围，达到了预期的勘查要求和目的。<br />
Ground collapse at the complex of Xiangyuan Primary School in Lanshan County, in order to find out the cause of the collapse and the hidden danger, therefore, electrical resistivity imaging was used to carry out geophysical survey on the foundation of the building of Xiangyuan Primary School Complex in Lanshan County, the occurrence of subsidence area and the existence of soil cave, karst and other adverse geological phenomena in the site are detected. The method is to set up 3 electrical resistivity imaging survey lines in the site, it is found that the collapse is caused by the weak stratum with low resistivity and water-cut in the site. The application of electrical resistivity imaging in this area has effectively proved the occurrence state and range of the subsidence area, the anticipated exploration requirements and purposes have been achieved.
