高速公路隧道地质超前预报方法比较

由于隧道工程属于隐蔽性工程,工程岩体地质条件复杂多变,为了更好地探明隧道围岩体内的各种缺陷,并预测预报可能引发的隧道地质灾害的不良地质体的位置、规模和性质,为后续工程开挖与支护提供合理的措施,采用相应的地质超前预报是重要且必要的.根据隧道工程界常用的地质超前预报方法,对其使用方法、作用原理及其特点进行对比分析,以便借鉴采用.

Comparisons on Forecast Methods for Geology of Highway Tunnels

Because the tunnd project is covert and the geological eondition is complicated,is if very important and necessary to adopt corresponding advanced forecast method for geology in order to survey the tunnel walls,prediet the position,scale and characteristics of the ill rock which will possibly lead to geological disasters and provide rational rheasures for future digging and timbering. In this paper, analyses on this method commonly used in engineering are conducted.
