某高风险岩溶隧道区域岩溶水化学特征分析

Characteristic analysis on hydrochemistry of high risk areas of karst tunnel

结合岩溶发育规律理论,从岩溶发育四项基本条件出发,重点考虑了高风险岩溶隧道区域岩溶水化学特征,通过计算分析,得到该区域岩溶水化学特征,推断高风险岩溶隧道所处区域不同岩组岩溶发育程度,评估不同岩组对该高风险岩溶隧道所产生的风险,从而对该隧道的施工具有一定的指导意义。

Combining with the theory of karst development law and according to four basic conditions, especially the hydrochmaistry characteristics of high risk areas of karst tunnel, hydrochemistry characteristics of the areas of karst tunnel are reward by means of computation and analysis. So development extent of karst areas of different rock formation of high risk karst tunnel is deduced. And the risk of different rock formation to the karst tunnel is evaluated. It is certain guiding significance for the karst tunnel constructed.
