Abstract
In this paper, we have studied the expected problems when tunnel is excavated under the wetland, and described the measure to maintain the wetland's ecosystem environment. Firstly, we investigated the wetland's ecosystem such as plants and animals, and executed ground investigation including in-situ tests and geophysical survey. And we analyzed the foreign similar cases for tunnel excavation near the wetland. We also evaluated the runoff and infiltration quantity of groundwater and hydraulic behaviour of rock mass and wetland by numerical analysis. Finally, we established the effective measure to minimize the ecosystem's influence by tunnel excavation.
