摘要
在工程建设中,常遇到溶洞、采空区等地质体问题,从而引起地面裂隙、塌陷等危害。因此,在工程建设前,需要查明这些地质体的分布范围和大小情况。工程中常采用精准的钻孔方法,然而该方法往往以点代面,不能反映地下地质体的总体规模和分布形态。目前,高密度电法因为具备探测深度大、探测精度高等优点,在工程地质勘查中得到了越来越广泛的应用。为了初步查明建设用地范围内土层厚度以及探测岩溶发育的情况,本次项目采用高密度电法进行数据测量,并综合解释成图,验证了高密度电法应用于岩溶探测的可行性,为工程建设提供了可靠的质量保证。
In engineering construction, geological problems, such as caves, goaf, which are often encountered, often cause ground fissure, ground collapse, etc. Before the construction, therefore, project contractor needs to find out the distribution and size of geological conditions. Precision drilling method is often adopted in engineering, but this method often points to the face, which can not reflect the overall size and distribution of the underground geological bodies. At present, the high density resistivity method has been widely used in engineering geology exploration, because of its big probing depth and high detecting precision. In order to basically find out the soil thickness range of a certain construction land, and detect the karst development situation, this project used the high density resistivity method to collect the field data and to comprehensively interpret it, verified the feasibility of high density resistivity method applied in the karst cave, and provided a reliable quality assurance for the relevant engineering construction.
