MgCl_2溶液对水泥土力学性质的影响

The Mechanical Properties Effects of MgCl_2 Solution to the Cement Soil

为研究水泥土在侵蚀性溶液影响下的力学性能,进行室内模型试验,自制含有侵蚀性物质的配置水,研究水泥土在氯化镁溶液中浸泡7d、14d、28d后的无侧限抗压强度规律,得出:随着浸泡时间的延迟,水泥土的无侧限抗压强度增加;随着浸泡溶液浓度的增加,水泥土的无侧限抗压强度降低;在短期时间内,水泥土的无侧限抗压强度受化学侵蚀影响较小。

For the sake of researching the mechanical property of cement soil under infuluence of aggessive solution, labratory tests are conducted, prepare solution that contain erosive substance, study variation law of unconfined compression strength of cement soil which have soak in MgC12 solution for 7, 14, and 28 days, the following conclusion are drawn： 1 As soaking time goes on,the unconfined compression strength of cement soil enhanced; 2 With increasing of density of the agres- sire solution,the unconfined compression strength of cement soil decreased; 3 In short time,the aggressive solution have little influence on the unconfined compression strength of cement soil.
