摘要/Abstract

摘要： 基于EH-4大地电磁成像系统的工作原理和特点、现场探测方法以及后期数据处理优势，对某强风化边坡进行了现场探测，掌握了其低电阻层在空间上的分布，并结合钻孔数据和地质分析，对地层岩性进行了解译，查明了软弱结构层的分布。工程实例分析表明该方法可对强风化边坡内赋存的软弱结构层进行超前的宏观预测，值得在相关领域推广运用。

Abstract: Based on the working principle and characteristics，on-site detection and the post data processing of EH-4 magnetotelluric imaging system，a highly weathered rock slope is detected on site to grasp the spatial distribution of its low resistivity layer.Combined with drilling data and geological analysis，the formation lithology is interpreted，and the distribution of weak interfaces is determined.The engineering practice shows that EH-4 provides advanced macro forecast for weak interfaces of the highly weathered slope which is worth to be applied and popularized in related fields.

Key words: EH-4 electromagnetic imaging system, Highly weathered slope, Weak interfaces
