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 通過對水泥?水玻璃加固土的無側(cè)限抗壓強(qiáng)度試驗,以及用不同酸堿性水制成與養(yǎng)護(hù)的固結(jié)土所進(jìn)行強(qiáng)度對比試驗,得出軟土的物理力學(xué)性質(zhì)指標(biāo)與加固土的抗壓強(qiáng)度之間存在一定的相關(guān)關(guān)系,即隨著含水量、孔隙比、孔隙度、液塑限及液性指數(shù)的增加,水泥?水玻璃加固土的抗壓強(qiáng)度相應(yīng)地降低;而隨著原狀土的容重、壓縮模量的增加,水泥土的抗壓強(qiáng)度也隨之增加。
