摘要
隧道施工过程中,超前地质预报的准确性非常重要.该文以梁王山斜井施工为背景,采用数字化多要素隧道超前地质CT、地质雷达三维探测以及瞬变电磁三种方法相结合,进行超前地质预报,为隧道施工设计提供了可靠的地质依据.通过与掌子面超前钻探结果进行对比分析,表明该综合超前地质预报方法与实际地质情况吻合度较好.
Abstract
In the process of tunnel construction,the accuracy of advanced geological forecast is very im-portant.Based on the construction of Liangwangshan inclined shaft,the advanced geological forecast is carried out by combining three methods of digital multi-element tunnel advanced geological CT,geological radar three-dimensional detection method and transient electromagnetic method,which provides a reliable geological basis for construction design.Compared with the advanced drilling results of the tunnel face shows that the comprehensive advanced geological forecast method is in good agreement with the actual geological situation.
