固化土材料的试验研究

Experiment research on solidified soil materials

固化土材料是通过在土壤颗粒间的胶联作用改变土壤原有的亲水性能 ,使土壤得到固化。通过在我国部分水利工程中的应用实例表明 ,固化土材料具有优良的抗渗性能 ,在我国南方地区没有冻害破坏的条件下 ,可直接用于修筑防渗输水渠道等水利工程中 ,在我省北方寒冷气候条件下 ,抗冻指标达不到要求 。

From the glue combination effect among soil grain to change the native hydrotropism to solidify the soil. Part of hydraulic utilization practices in China shows that the solidified soil material has good seepage prevention capactity.Under the situation of no_freezing disaster damage in the southarea of China,it can be directly untilized in building some hydraulic project such as seepage prevention water_carrying ditch.And under the situation of cold climate in the north of Heilongjiang Province,it is not suitable to be blindly developed and utilized causing by unreached freezing prevention target.
