摘要

研究目的:隧道开挖过程中常遇到岩溶、塌方、涌水等不良地质现象，为确保施工安全，超前地质预报应运而生。其中TSP地质超前预报由于具有适用范围广，预测距离远，精度高,操作简单，成果丰富，对施工干扰小，预报工期短等特点，已成为国内外隧道地质预报的常用方法之一。

研究结论:李家营隧道采用TSP技术成功地进行了预报，并验证了预报成果，证明TSP方法能够及时地了解掌子面前方100~150 m内的地质情况，并且能够及时提交掌子面前方预报结果，同时TSP预报实施步骤比较简单,可在不影响施工的前提下在隧道中进行作业。为隧道的正常施工和及时地调整支护参数提供依据，能够有效地控制施工安全事故的发生。

Abstract

Research purposes: The unfavorable geologic phenomenon, such as karsts，collapse, and water bursting etc.，are often encountered during tunnel excavation. In order to ensure the construction safety, the advanced geological forecast should be conducted. The TSP advanced forecast becomes one of commonly-used geological forecast methods at home and abroad because of its wide application scope，far forecast distance，high accuracy，simple operation, rich results ,less influence on construction and short forecast period.

Research conclusions: The TSP forecast technology was used for the Lijiaying Tunnel and it worked well. The forecast results proved that by using the TSP method, the geological conditions of the area within 100-150 meters in front of the working face of the tunnel could be well known timely, and also the forecast result could be sent timely. Meanwhile, the applicable procedures of TSP forecast method were so simple that it was possible to carry on the forecast work without the influence on the tunnel construction. With the TSP technology, the basis could be provided to the tunnel construction and parameter adjustments to guarantee the construction safety.
