地下水硫酸盐浓度对水泥土剪切性能影响试验分析OA

This study investigates the deterioration effects of groundwater sulfate solutions with different concentration gradients on the mechanical properties of cement-soil through laboratory shear strength tests.The results indicate that when the sulfate solu tion concentration increases by 0.5 mg/L,the shear strength parameters of the cement-soil specimens show a regular attenuation.Under long-term erosion conditions,a significant linear correlation exists between the sulfate attack duration and the reduction of shear strength.It is found that the frictional characteristics are more susceptible to damage caused by groundwater sulfate attack.The find ings provide a reference for the durability design of geotechnical engineering structures in similar regions.
