TSP在公路隧道超前地质预报中的应用研究

根据TSP技术的特点,将TSP技术应用于掌子面前方不良地质对象的预报工作中,同时比较了基于地质雷达和基于TSP的预报结果。水平地质钻探与现场开挖的实际情况表明,基于TSP技术的隧道超前预报,在预报距离,预报的准确性,以及对围岩的判别等方面,均明显优于传统的地质雷达。文章最后还指出了该技术存在的一些待进一步研究的问题。

Application of TSP in the expressway tunnel geological prediction

Geological disasters such as collapse, cavity and water-emerging, often occurs during the road tunnel construction in the westward complex mountainous area, and the traditional geophysical methods could not predict the character, scale, position, shape of the rupture, karst-hole, crash-strip, even rock type in front of the face, so the paper applies the TSP method to the prediction of the bad geological objects based on the character of the TSP. By the actual application of project, comparing the results of the TSP and geological radar, and validated by the actual fact of the level drilling and digging, all of these show that application of TSP in expressway tunnel geological prediction, not only to the distance, but also to the veracity and distinguishing of rock, is far precise than the geological radar.
