Water Inflow Quantity Evaluation and Prediction for Cimushan Tunnel

Abstract:

Tunnel excavation breaks the original hydrological dynamic balance, promotes water cycle and influences the mountain groundwater system to some extent. Water inflow during construction not only threatens construction safety, but also affects surface vegetation’s growth. Taking tunnel 1 in Chongqing Cimushan area as the project background, and through analyzing the hydrological test results from tunnel exploration stage, counting the actual water inflow quantity in construction period, doing the 3-D finite element numerical modeling, we analyzed and evaluated the tunnel water inflow quantity, to provide reference for recognizing the harm of groundwater and making treatment measures.
