EH-4高频大地电磁测深勘查采空区的效果分析

在铁路、公路、管道铺设等工程项目中,采空区的存在在线路选线、施工过程中都将产生各种安全隐患.根据采空区的不同规模所需采取的设计方案、整治措施各有不同,因而采空区的有效勘探成了后续工作得以顺利施展的前提条件.基于EH-4高频大地电磁测深法,对几种不同地质条件情况下的采空区进行勘探,判别了测区采空区异常.依据物探资料布设了...

Analysis of the EH-4 High-Frequency MT Sounding Method in Gob Exploration

In the construction of railways,highways and pipelines,the existence of gob areas may pose a variety of security risks in the route selection and construction process.As different sizes of gob areas need to be taken in different design,different remediation measures,the effective gob exploration has become a prerequisite for casting the follow-up work smoothly.In this paper,it explores the gob areas under different geological conditions,and determines the anomalies of gob areas based on the principle of the...
