贵昆铁路乌蒙山2号隧道TSP施工技术

TSP Method in Mountain Wumeng No.2 Tunnel Engineering

隧道掌子面前方和周围的不良地质条件极易引起隧道塌方、涌水,导致人员伤亡、设备毁坏、工期延误,造成重大损失,因此需要采取合理的超前地质预报方法对可能发生地质灾害进行预报。文章就贵昆铁路乌蒙山2号隧道工程中应用的TSP远距离超前探测施工技术方法进行讨论,并提出TSP在特长隧道超前地质预报中的重要作用。

The unfavorable geological conditions around and in front of the working face in tunnel engineering will cause collapse of tunneX and surge of underground water resulting in tremendous causalities and equipment damage, Therefore reasonable advance geological prediction method should be adopted to avoid the possible geologic hazard. The article dissects TSP method used in Mountain Wumeng No.2 Tunnel along Railway Gulyang-Kunming and stresses the important role TSP plays in ultra long tuunel engineering.
