根据模型相似理论中几何相似、荷栽相似、边界条件相似,制作出与实际相似的模型进行试验,来对比研究雅安过湿土和处治后的改良土的差异。试验结果表明:改良过湿土承载力得到提高,沉降量明显小于过湿土,水稳定性得到提高,达到了过湿土改良的目的,说明采用掺灰法处治过湿土是一种切实可行的办法。

According to geometric similarity, load similarity theory, a model similar to the actual condition is established to improved soil in Ya 'an. The test results showed that the and boundary conditions similarity in similarity compare the difference between overwet soil and bearing capacity of improved overwet soil was increased, the settlement was significantly reduced, and water stability was improved, which achieved the purpose for improvement of overwet soil. It is indicated that lime mixing method is feasible to treat overwet soil.
