摘　　要：拟建的山西工程技术学院21^(#)、22^(#)两栋公寓楼,其下部有耐火黏土采空区,需查明地下采空区的分布范围及特征。根据岩土工程勘察资料显示,耐火黏土埋深在18~28 m.运用高密度电法勘探,以拟建两栋建筑为中心,依据地形及地貌特征,布置8条勘探线,剖面总长1440 m,共计480个勘探点,并采用RES2DINV高密度电阻率数据二维反演软件对数据进行处理,结合钻孔资料,对数据进行分类分析并勾划出耐火黏土采空区的分布范围,为下一步对采空区进行处置,保护拟建筑物的安全提供基础。同时,为高密度电法勘探研究工作提供思路。There is a goaf of refractory clay under the two apartment buildings to be built in Shanxi Institute of Engineering and Technology—No.21 Apartment and No.22 Apartment.It is necessary to find out the distribution range and characteristics of the goaf.According to the investigation data of the geotechnical engineering,the buried depth of the refractory clay is between 18~28 meters.In this paper,with building the two apartments at the core,eight exploration lines will be set by the high-density electrical exploration method according to the geomorphological characteristics there,with a total section length of 1440meters and 480 exploration points.RES2DINV—the two-dimensional inversion software in high-density resistivity method is adopted to process the data.Then,the data are classified and analyzed with the combination of drilling data,thus defining the range of the goaf of refractory clay.All these efforts will lay a foundation for the following disposal of the goaf and protection of the two apartments to be built.At the same time,a reference for the researches of the high-density electrical method will be provided to explore refractory clay.
