工程地质中水文地质勘察情况分析

Analysis of Hydrogeological Survey in Engineering Geology

水文地质勘测是工程建设中的一项基础工作,根据勘察侧重点的不同,又可以分为供水水文地质勘察、综合水文地质勘察两种类型。现阶段常用的水文地质勘察技术有若干种,如测绘法、物探法、可控源音频大地电磁法及高密度电法等。每一种勘察方法的操作要点、适用条件及技术优势均存在一定差异,在工程地质勘测作业中应根据现场情况灵活选择。除了要熟练掌握每一种技术外,还应构建完善的工程地质勘察体系,提高勘测数据内容的精确性,发挥水文地质勘察的作用,为工程施工的高质量开展提供有益帮助。

Hydrogeological survey is a basic work in engineering construction.It can be divided into two types:water supply hydrogeological survey and comprehensive hydrogeological survey according to different survey emphases.At present,there are several commonly used hydrogeological survey technologies,such as surveying and mapping method,geophysical method,controllable source audio frequency magnetotelluric method and high-density electrical method.There are some differences in the key points of operation,applicable conditions and technical advantages of each survey method,which should be flexibly selected according to the site conditions in the engineering geological survey.In addition to mastering each technology,we should also build a perfect engineering geological survey system,improve the accuracy of survey data,give full play to the role of hydrogeological survey,and provide useful help for the high-quality development of engineering construction.
