物探方法在土石坝隐患探测中的应用

Application of geophysical methods to detect risks in earth-rock dam

土石坝工程经多年运行后会不同程度地形成一些隐患,甚至会发展为病险工程,查明隐患成因、分布及影响范围对工程除险加固处理方案的设计与施工具有重要指导意义。本文结合几个工程实例对土石坝常见病险隐患的探测方法及效果和灌浆处理效果检测做了介绍,阐述了用于隐患探测的常用物探方法在工作布置、参数设置和资料分析等方面的问题和综合物探的意义,以供类似工程参考借鉴。

After years of operation,some risks of different degree in the earth-rock dam probably formed,and some dam maybe develop into dangerous project. Identifying cause,distribution and influence range of the hidden risks is significant to the risk elimination design and implementation. The detection methods and their effects for earth-rock dam hazard investigation and the grouting treatment effects of some projects is introduced in this paper. The arrangement,acquisition parameter setting and data analysis of common geophysical methods to detect hidden risks of earth-rock dam is presented. The significance of the comprehensive geophysical prospecting method is also expounded. The analysis could provide a reference for similar projects.
