摘要：With the rapid development of China's trans- portation and water conservancy industry, a large number of tunnel projects appear. Geological disas-ters such as landslides and water gushing caused by adverse geological conditions often occur, causingserious damage to the surrounding ecosystem, caus-ing great economic losses and security risks. As a joint prediction technology combining electrokinetic effect and TSP. TSEP has become a new method of ecological environment protection in underground tunnel engineering. This paper introduces the devel- opment status and basic principle of TSEP technol- ogy and discusses several key factors affecting TSEP data acquisition. The TSEP test was carried out in the lishanping tunnel of the Shuiqing section of Chong-qing Kunming expressway, and the prediction results of TSEP were obtained. The results are consistent with the distribution of rock mass and water body inthe subsequent excavation, which verifies the feasi- bility and effectiveness of the application of TSEPtechnology in the ecological environment protection of tunnel engineering.
