综合物探方法在次生地质灾害调查中的应用

地面塌陷多属工程建设、资源开发所引发的次生地质灾害,查明其成因及影响范围对工程处理方案的设计与施工有重要指导意义。本文结合某实际工程对次生地质灾害产生的地质原因进行了分析,并对用于因工程建设所致地灾调查的综合物探方法及勘察效果予以介绍,阐述了诸如高密度电法、瑞雷波探测、地震映像及剪切波测井等方法在地面塌陷原因分析和展布空间探测等方面的资料解译方法及有效性,以供类似工程参考。

Application of comprehensive geophysical prospecting methods to investigation of secondary geological disasters

Ground collapse mostly belongs to the secondary geological disasters caused by construction, resource development, and to identify its causes and influence scope has important guiding significance for the design and construction of engineering processing schemes. The geological reasons of secondary geological disasters for certain engineering project are analyzed, and the integrated geophysical methods and the prospecting effects in the investigation of the secondary geological disasters from engineering construction are introduced. The data interpretation methods and the effectiveness of geophysical methods such as high-density electrical method, Rayleigh wave exploration, seismic imaging and shear wave logging in the ground collapse cause analysis and the distribution space exploration are expounded, which can provide the reference for similar engineering.
