| 摘 要： | 基于Archie法则,通过试验计算出水泥土试块受不同浓度硫酸溶液侵蚀后的胶结系数,研究了水泥土基本物理参数、电阻率参数同胶结系数之间的关系,最后对硫酸侵蚀水泥土的化学机理进行了浅析。研究表明,受硫酸侵蚀后,胶结系数随着硫酸溶液质量浓度的增加而增加,含水量、孔隙率、孔隙比、水泥土电阻率均随着胶结系数的增加而减小,它们呈线性关系,具有较高的相关性,化学反应是导致胶结系数发生改变的根本原因。

| Abstract: | Through the experiment of soil-cement block eroded by different concentration of H2SO4 solution in lab,the shape factor related with H2SO4 solution was calculated.The relationships of various parameters and electrical resistivity to shape factor were studied by using electrical resistivity method.Finally the chemical mechanism of erosion by H2SO4 is analyzed briefly.The result indicates that after erosion,the shape factor increases with the increment of H2SO4 solution concentration;the water content,porosity,void ratio and electrical resistivity decrease with the increment of shape factor,their relationships are linear.The basic reason for the change of shape factor is the chemical reaction. |
