The unconfined compressive strength , shearing strength and permeabi lity of stabilized soils were tested in laboratory , the strength of contaminated composite soils sampled with different ph and soaped in corresponding ph were compared . the results from experiments indicate that there exists a certain relationship between the soft soil properties and the unconfined compressive of grouted soil . with the increase of water content , porosity ratio , degree of porosity , plasticity limit , liquid limit and liquid index , the compressive strength of cement - sodium silicate - stabilized soil decreases , while increases as the bulk weight and compressibility modulus 通过对水泥?水玻璃加固土的无侧限抗压强度试验，以及用不同酸碱性水制成与养护的固结土所进行强度对比试验，得出软土的物理力学性质指标与加固土的抗压强度之间存在一定的相关关系，即随着含水量、孔隙比、孔隙度、液塑限及液性指数的增加，水泥?水玻璃加固土的抗压强度相应地降低；而随着原状土的容重、压缩模量的增加，水泥土的抗压强度也随之增加。
