Research of Water Inflow Impact on Ecological Environment for Cimushan Tunnel

Article Preview

Abstract:

Tunnel excavating breaks the original hydrological dynamic balance, promotes water cycle and interchange, the influences extent to groundwater flow system and groundwater level by tunnel discharge has direct connection with structure of groundwater aquifer system. The factors which impact ecological environment including the depth of groundwater, groundwater mineralized degree, suspended moisture content and salt content etc., of which, Groundwater level is very important to the survival of vegetation. Analyzing tunnel’s water inflow and the change of seepage field impact the groundwater level, the change of surface water and groundwater quality and the ecological environment influence of nearby tunnel. Studying the water inflow of tunnel impact on the tunnel site, which provide a reference of correct implementation of the tunnel construction principles “prevention, drainage, cut, plug union, adaptation to local conditions, and comprehensive management of water” when build tunnel in similar geological conditions of landscape areas.
