综合物探方法在河北保定向阳村地面塌陷区调查中的应用

Application of synthetical geophysical method to ground collapse zone research of Baoding Xiangyang village

向阳村地下土体层在水的作用下非均匀流失引起地面坑(洞)沉降、塌陷,直接造成房屋损毁,严重影响村民正常生产生活秩序。采用高密度电法和浅层地震勘探等综合物探方法,对地面塌陷灾害区开展调查工作,可查明调查区内地层分层结构、岩土层厚度和隐伏断裂破碎带分布状况,并预测划分出塌陷危险区、塌陷预防区和相对稳定区,为后续灾害治理工作确定具体范围,给治理施工设计提供科学依据。

Xiangyang Village underground soil layer under the action of water, non-uniform loss caused by the ground pit （hole） subsidence, collapse, a direct result of the houses were destroyed, seriously affected the villagers＇ normal production and life order, using integrated geophysical methods for high density electrical and shallow seismic exploration, survey work on the collapse area, identify the survey area, the stratigraphic hierarchy, the soil layer thickness and the buried fault fracture zone distribution, and predict the division of the collapse danger zone, collapse prevention area and a relatively stable area, determine the specific scope, designed to control construction to provide a scientific basis for follow-up disaster control work.
