中文摘要:
      隧道超前地质预报的方法有多种,但每种方法都有一定的不足,单一的预报方法难以得到满意的结果。为提高预报精度,基于开挖面揭示围岩情况,在紫云隧道地质超前预报中采用TSP与瞬变电磁法相结合的方法准确预报了开挖面前方富水地质体的存在。工程实践表明,采用多种手段相互印证的方法,可以有效提高预报结果的准确性,从而指导隧道安全施工。
英文摘要:
      There are various methods to predict tunnel geology in advance, but each of the methods adopted has certain shortcomings. It is difficult to achieve satisfactory results by means of a single forecasting method. In order to improve the prediction accuracy, the TSP TEM Combined Method is applied to accurately predict the existence of water rich geological bodies in front of the excavation face of the Ziyun Tunnel upon the basis of the revelation of the surrounding rock conditions by the work face. Engineering practice shows that the method of mutual verification by multiple means can effectively improve the accuracy of the prediction results and guide the safe construction of tunnels.
