Hydrogeochemical characteristics and identification of water source in Huayingshan Tunnel District
摘要
Abstract
In order to predict the potential water inrush problem produced during the construction of Huayingshan tunnel, the research analyzed the hydrogeochemical characteristics of the surface water, groundwater and inrush water of Huayingshan tunnel, and identified the inrush water resource based on the field investigations and hydrochemical analysis of water samples.The result shows that,in Huayings-han tunnel area the main hydrochemical types of regional water are HCO 3-Ca and HCO3· SO4-Ca. The water quality is in alkalescency,and the hydrochemical origin of water is rock weathering.There is close relationship between shallow groundwater and surface water.Precipitation is main supply sources of all kinds of water.Replenishment elevation of study area is 315~1467m.In the southeast region the tun-nel inrush water mainly comes from sandstone aquifers of upper Triassic Xujiahe formation(T3xj)and middle Jurassic Xintiangou formation(J2x),and the northwest comes from limestone karst aquifer of lower Triassic Jialingjiang formation(J1x).关键词
