NUMERICAL SIMULATION ABOUT THE CONSTRUCTION OF CHENGDU SUBWAY LINE 2 IMPACT ON THE GROUNDWATER ENVIRONMENT

As an example of the first phase project of Chengdu Subway Line 2, use three-dimensional numerical simulation of groundwater flow to simulate the situation of ground water table obstruct, Simulation includes two cases of only consider Line 2 and both consider Line I, 2. Through the analysis that Chengdu Subway Line 2 project of ground water table obstruct in 0.035 similar to 0.298m, Will be affected some low-rise or middle-rise buildings safe and the normal use of the basement or underground car park which relatively poor water resistance.
