On basis of the data of unlimited compress strength experiments , the paper gets the relationship between unlimited compress strength of lime - soil and the quantity of added lime . the paper also discusses the reason why the lime can dispel the expansive and shrink quality of expansive soil 通过无侧限抗压强度试验，得到石灰土无侧限抗压强度与掺灰量的关系及龄期对石灰土无侧限抗压强度的影响，同时对石灰改善膨胀土的机理作探讨。

In order to establish the non - destructive detecting standard , transverse wave speed is chose as the non - destructive detecting parameter , which strongly correlated with the compressive strength basing on lots of room experiments , and finds the relation between transverse wave speed of cement - soil and its contributory factors . the forecast model of the non - destructive detecting parameter is established by neutral - network toolbox of the matlab . by this model , transverse wave speed and compressive strength are got by putting the soil style , cement - soil ratio , water - cement ratio , maintain condition and the time 由于水泥土的力学性能通常用抗压强度来衡量，因此，我们通过大量的水泥土室内试验建立了剪切波速与抗压强度以及影响因素之间的对应关系，并利用matlab神经网络工具箱建立了防渗墙施工质量无损检测指标的预测模型，即通过输入土类、灰土比、水灰比、养护条件及龄期获得相应的剪切波速和抗压强度。
