中文摘要：

通过模拟试验的方法探讨了在不同无机化合物溶液环境中不同龄期的水泥土表观和抗压强度变化规律，得出各种无机化合物环境对水泥土作用的大小排序为Na2SO4〉MgSO4〉H2SO4〉MgCl2〉CaSO4。当溶液当中都存在SO42-时，阳离子对水泥土作用大小排序为：Na＋〉Mg2＋〉H＋〉Ca2＋；当溶液都存在Mg2＋时，阴离子对水泥土作用大小排序为：SO42-〉Cr。对各个环境的主要介质进行计算、对比分析揭示了环境对水泥土的作用机理，其中H2SO4，MgSO4和MgCl2环境对水泥土腐蚀是分解型腐蚀与结晶型腐蚀的复合型腐蚀；Na2SO4环境对水泥土腐蚀是溶出型腐蚀与结晶型腐蚀的复合型腐蚀；CaSO4环境对水泥土无腐蚀作用。

英文摘要：

In order to simulate and study the corrosion effect, the unconfined compression tests ot the cemented soft samples were performed. The samples were soaked in various inorganic compound solutions with different concentrations for various times. The results show that inorganic compound solutions could be arranged in a series for the influence as follows： Na2SO4〉MgSO4〉H2SO4〉MgCl2〉CaSO4. When the solutions contained SO42- anion, the influence degrees of cations were Na＋ 〉 Mg2＋ 〉 H＋ 〉 Ca2＋. When the solutions contained Mg2＋ cation, the influence degrees of SO42-anion was greater than that of Cl-anion. By calculating the main chemical ingredients and analyzing the mechanism, the corrosive type of H2SO4, MgSO4 and MgCl2 solutions to cemented soil is a composite type of resolving and crystallizing combination; that of NazSO4 solution to cemented soil is a composite type of dissolving and crystallizing combination; CaSO4 solution shows no corrosive action to the cemented soil.
