开展了不同水化学腐蚀下砂浆试样的常规三轴压缩试验，分析了溶液pH值、浓度及水化学成分对试样的腐蚀程度及微细观结构的影响效应，探讨了砂浆试样的水化学腐蚀机理，并进一步对比分析了不同水化学作用对砂浆物理力学参数的影响规律。基于化学腐蚀后试样产生的次生孔隙率，建立了新的损伤参量来定量描述试样物理力学性质随水化学损伤的演化过程。

Triaxial compression tests of mortar specimens under various hydrochemical environments were carried out .T he effects of the pH、concentration and composition of chemical solution on the corrosiveness and micro/meso structure of the mortar specimens were evaluated . The hydrochemical corrosion mechanisms of the mortar specimens were explored and the results revealed further influence of various hydrochemical actions on physical and mechanical parameters of the mortar specimens . A new damage parameter was proposed based on the mortar secondary porosity caused by chemical corrosion ,which can quantify the evolution process of the physical & mechanical parameters of the mortar specimens during its hydrochemical damage .
