地空瞬变电磁法在复杂地形隧道勘察中的应用
Application of Ground-Airborne Transient Electromagnetic Method in Tunnel Surveying in Complex Terrain
摘要
Abstract
Traditional ground geophysical exploration methods and geological survey techniques are often constrained by site and terrain conditions,making them ineffective for detecting geological hazards in tunnel areas.The application of the ground-airborne transient electromagnetic(GATEM)method in tunnel geological hazard exploration under complex terrain conditions can effectively overcome these limitations.The GATEM method utilizes a rotor unmanned aerial vehicle as the platform and surface linear sources as the emission sources,offering advantages such as rapid and simple deployment and greater exploration depth.Based on the working process of the GATEM method in complex terrain,a case study of the Mengjiaya Tunnel on the Yichang-Fuling high-speed railway was conducted.The survey successfully identified karst development and safety hazards in the proposed tunnel area,achieving excellent exploration results.The GATEM provides valuable references for tunnel design,evaluation,and disaster prevention,while also verifying its reliability and advantages under complex terrain conditions.关键词
