摘要
近年来,随着隧道施工技术的提高,对隧道施工期地质超前预报提出了更高的要求。受地质勘察精度、经费等诸多条件的限制,设计与实际不符的情况屡有发生,由此造成的隧道洞内塌方、涌水、涌泥、涌砂、岩爆、瓦斯爆炸等灾害时有发生,给隧道施工造成极大的危害。隧道施工期地质超前预报显示出越来越重要的作用。 本文在回顾隧道施工期地质超前预报技术的发展及其应用的基础上,对隧道施工期地质超前预报技术的发展前景进行了预测。
With the development of tunnel construction technology, more and more requirements with high standa'rd for geological forecast in tunnel construction have been raised. And the design is handicapped by the accuracy of geological investigation, outlay and so on. As a result of unconformity between design and actual situation, collapse, water inflow, rock burst and gas burst usually take place in tunnel and it makes exceeding harm to tunnel construction. Therefore the geological forecast in tunnel construction is playing very important role. In this paper, the development and application of geological forecast technology in tunnel construction is reviewed and its prospect is foreseen hereafter.
