摘要
随着水泥土搅拌法在工程中的广泛应用,环境侵蚀对其影响的问题逐渐暴露出来。本文通过自制水泥土试块,配置不同浓度的MgSO_4和MgCl_2溶液模拟环境侵蚀,测试了不同侵蚀环境中水泥土的无侧限抗压强度。结果表明,在环境侵蚀作用下:应变较小时水泥土就会产生破坏;水泥土的强度在一定程度上受到了影响,在工程应用中应该将环境侵蚀作为其强度的影响因素进行考虑;在NaCl溶液的环境中,MgSO_4溶液对水泥土的抗压强度影响低于MgCl_2溶液。
With the stirring method of the cement stabilized soil widely used in the engineerings, the influence of the environment erosion on it is gradually exposed. This paper tested the unconfined compressive strength of the cement stabilized soil in different erosion environments by the self-made samples with different concentrations of MgSO4 and MgCl2 simulating the erosion environments. The results show that under the action of environmental erosion, the cement stabilized soil will be destroyed when the strain is small. The strength of it is affected to a certain extent. The environment erosion should be considered as a factor affecting its strength in the engineering applications. In the environment of NaCl solution, the effect of MgSO4 solution on the compressive strength of cement stabilized soil is lower than that of MgCl2 solution.
