摘要

通过室内试验模拟了水泥土试块受不同浓度硫酸（H2SO4）溶液侵蚀的过程，采用电阻率法研究了电阻率与各参数、无侧限抗压强度之间的关系。结果表明，受H2SO4侵蚀后，水泥土电阻率、孔隙水电阻率、水泥土抗压强度均随着溶液浓度的增加而减小，而水泥土的结构因子和重度均随着溶液浓度的增加而增加，水泥土抗压强度与水泥土电阻率成正比。在试验的基础上，考虑侵蚀因素对水泥土电阻率的影响，通过对Archie法则进行修正，得到了H2SO4侵蚀下水泥土电阻率模型。通过对无侧限抗压强度试验结果的分析，并结合试块表观变化，提出了利用电阻率来评价侵蚀程度的方法。

Abstract

The erosion process of cemented soil blocks by H2SO4 solution with different concentrations is simulated through tests in lab. The relationship of the electrical resistivity with various parameters and unconfined compression strength is studied using the resistivity method. The result has shown that after eroded by H2SO4 solution

the electrical resistivity and compression strength of cemented soil are decreasing

whereas the formation factor and the density of cemented soil are increasing with the increment of H2SO4 solution concentration; the compression strength of cemented soil blocks is in proportion to electrical resistivity. By taking into account the erosion factor

a electrical resistivity equation related to H2SO4 concentration and porosity is proposed using the corrected Archie’s law. After analyzing the results of unconfined compression strength test and observing the photos of sample surface erosion

a method is proposed to evaluate the erosion degree of cemented soil eroded by H2SO4 solution through the electrical resistivity.
