摘　　要：城市住宅开发建设中经常会遇到隐伏灾害地质体,如岩溶、空洞、软弱层等,危害施工安全.文章以湘潭某在建小区为例,利用高密度电阻率法进行基础探测工作,探测结果为工程建设的灾害处理提供科学依据.工作区布置8条测线,以典型测线L7和L8为例,对其探测结果进行重点解释分析;根据测线的探测成果,最终圈定高阻和低阻异常体共13处,推测出勘探区域内溶洞的分布情况,并经后期钻孔资料进行验证,得到了预期较好结果.结果分析表明,高密度电阻率法在城市住宅开发建设勘探中具有良好探测效果,值得进一步推广使用.In the development and construction of urban housing,hidden disaster geological bodies,such as karst,cavities,weak layers,etc,are often encountered,which endanger construction safety.Taking a residential area under construction in Xiangtan as an example,this paper uses the high-density resistivity method to carry out basic detection work,which provides a scientific basis for the disaster treatment of engineering construction.In this paper,8 survey lines are arranged in the work area,and the typical survey lines L 7 and L 8 are taken as examples to focus on their detection results interpretive analysis.According to the detection results of the survey line,a total of 13 high-resistance and low-resistance anomalies are finally delineated,and the distribution of karst caves in the exploration area is speculated,and the later drilling data are verified,and the expected good results are obtained.The results analysis show that the high-density resistivity method has a good detection effect in urban residential development and construction,which is worthy of further promotion and use,and provides certain references for related detection work in the future.
