摘要
分析了HEC,YS和水泥三种土壤固化剂的主要性能特点及其应用情况,通过正交试验测定了固化土的抗压强度和渗透系数。试验表明,适合杨凌地区土质特点的固化剂为HEC,其掺量为1∶8时固化土的渗透系数最小,施工用水量对固化土的性能亦有较大影响,应取最优含水率。
This paper mainly introduce HEC, YS and cement agent of stabilized soil main characteristic and apply. By orthogonal test determine the compressive strength and permeate coefficient ,choice one material and optimum pair(HEC 1∶8, content of water 19%), compare economic benefits to choiced and present apply material. The moistrue content deeply influced the characteristic of stablized soil, the coptimum ratio of water content shouled be choiced.
