超前地质预报在隧道涌水情况下的综合应用

Comprehensive Application of Advanced Geological Prediction under the Condition of Tunnel Gushing

在隧道开挖过程中,由于地质条件的复杂性和气候的变化,在雨季大气降水持续不断地补给地下,可能造成隧道大量涌水,影响正常的施工并危及隧道安全。在介绍地震波反射法、地质雷达、红外探水工作原理的基础上,结合工程实例详细分析各个方法在隧道大量涌水时的应用,并对各方法的探测成果进行对比分析。通过对比分析得知,采用综合超前地质预报方法可以实现在复杂地质情况下的各预报方法优缺点互补,使得预报结果更符合实际情况。

In the tunnel excavation process, because of the complexity of the geological condition and the variation of the climate, a great deal of water may flow over into the tunnel with the atmospheric precipitation supplying the underground constantly during the rainy season , which could impact the normal construction and even endanger the tunnel safety. On the basis of introducing the theory of seismic wave reflection method, geological radar and infrared detector, this paper, combined with an engineering example, detailedly ana water gushes out as we y 1 comparison and analysis, ses the applicationapp： addword： application of every method when amount of as the consequences of the methods comparing with each other. Through the using the comprehensive advanced geological forecast method can manage to make the advantages and disadvantages of each forecast method complementary under the complex geological situation, which makes the forecast consequence more in line with the actual situation.
