摘要
针对兰州地区上庄隧道渗漏水结晶病害问题,文章统计分析了发生渗漏水结晶物病害的特征,测定了相应隧道渗漏水、结晶化学组分,并借助层次分析法对结晶物组分来源进行了判别,计算结果表明:黄土隧道渗漏水结晶沉淀物的主要成分石灰石、白云石和水镁石中的Ca2+、Mg2+离子;CO32-主要来源于地下水溶解的CO2。
Aiming at the crystallization disease of leakage water occurred in the Shangzhuang tunnel in Lanzhou area,a statistical analysis on the characteristics of the leakage water crystal is conducted,the chemical components of leakage water and crystal are measured,and the source of crystal components is discriminated by means of analytic hierarchy process(AHP).The calculation results show that:the main components of the leakage water crystals of the loess tunnel are Ca2+and Mg2+ions in limestone,dolomite and brucite;CO32-mainly comes from the dissolved CO2 in groundwater.
