摘　　要：在工程勘察中,采用一定数量的钻孔并结合原位试验来确定地层的岩土性质,往往具有局限性,物探采用特定的装置和技术方法来获取地层的物理性质,往往具有多解性。通过综合物探不同的装置和技术方法来获取地层的各种物理参数,生成曲线图、断面图,并结合钻探及原位试验,以点带面,可以更为全面地了解地层的空间展布规律,推断结构特征,降低物探手段的多解性、钻探及原位试验的局限性,为勘察设计提供更加全面的信息。In engineering investigation, a certain number of boreholes and in-situ tests are used to determine the geotechnical properties of the stratum, which often has limitations. Geophysical exploration uses specific devices and technical methods to obtain the physical properties of strata, which often has multiple solutions. By integrating different geophysical devices and technical methods to obtain various physical parameters of the formation, generate curves and cross-sections, and combining drilling and in-situ test, point to area. We can more comprehensively understand the spatial distribution law of the formation, and infer structural characteristics, reduce the multiplicity of geophysical exploration methods, the limitations of drilling, and in-situ test, which provides more comprehensive information for survey and design.
