隧道超前地质预报TGP地震波法与地质雷达法适用性分析

Applicability of TGP Seismic Wave Method and Geological Radar Method for Tunnel Geological Forecast

隧道工程施工是一项十分复杂、施工周期较长的工作,并且施工中地质情况变化大,对于施工安全要求较高,因此如何准确、有效、快捷地对作业面前方的地质情况进行预报是许多工程技术以及管理人员面临的一大难题。针对目前我国公路工程隧道施工中常见的两种超前地质预报方法,阐述了其原理及应用情况,并进行了对比分析,以期为同行提供一定的参考与借鉴。

The construction of tunnel engineering is a very complex work with long construction cycle. The change of geological conditions in the construction is huge, and the safety requirement of construction is high. Therefore, how to forecast the geological conditions in front of work surface accurately, efficiently and quickly is a major problem for engineering technology and management staff. In allusion to two com- mon geological forecast methods in highway tunnel construction project, the principle and application of these two methods are elaborated and compared, in hope of providing reference for nears.
