| 摘 要： | 宝兰客运专线定西段黄土隧道施工中出现的工程地质问题主要因土体高含水率引起。单纯的物探法在黄土隧道超前地质预报中效果不理想,新方法的研究对于弥补物探法的不足及达到预报目的具有十分重要的意义。分析常规物探法的局限性,通过上庄隧道超前地质预报工程实例,提出应用综合分析法开展地质预报的新思路。

| Abstract: | Some engineering geological problems in the construction of loess tunnels of Dingxi section on Baoji-Lanzhou passenger dedicated line are caused by high moisture content of soil. The pure geophysical exploration method employed in advanced geological forecast of loess tunnel is far from satisfactory. It is great significant to look for new methods to make up for the shortage of the geophysical exploration method for good forecast results. This paper analyzes the limitations of conventional geophysical exploration method with reference to the advanced geological forecast of Shangzhuang tunnel and puts forward a new and comprehensive analysis method for geological forecast. |
