西南地区隧道工程条件下岩溶地下水系统变化特征分析
Analysis on Variation Characteristics of Karst Groundwater Systems under Tunnel Engineering Conditions in Southwest China
摘要
Abstract
The construction of tunnels have an impact on the intrinsic characteristics of karst groundwater sys-tem,such as the fall of the water table or the loss of surface springs.In this paper,the variation characteristics of karst groundwater system in southwest China under tunnel engineering conditions is summarized and is divided into three categories according to the types(covered,uncovered and buried)of the aquifers,structural features, supply characteristics,the runoff ways of karst water and the engineering characteristics of tunnel construction. The paper also presents typical examples (Jinzhi river groundwater system)illustrating the analysis process that different tunnel plans produce different effects on karst groundwater system,and compares the results with avail-able tunnel seepage volume.As a result,the study can be used as a reference for the geological disaster preven-tion of tunnel water-bursting.关键词
