为了验证固化剂GX08加固杭州海湖相软土的效果及考察有机质对水泥固化的不利影响,对吲化土的强度特性进行了试验研究。结果表明,有机质的添加会显著阻碍固化土强度的增长,而固化剂GX08能有效增强固化土的强度;固化土强度与有机质含量存在二次函数关系,与水泥掺量呈线性关系,与固化剂GX08掺量和龄期都以对数函数的形式相关;将总灰水比C/W用于固化土强度模型的建立,通过对试验数据的分析与整理,建立了同时考虑固化土中有机质含量、水泥掺量、固化剂掺量和龄期影响的固化土综合强度预测模型。最后对模型进行了推广使用,验证了模型的适用性。
To validate the stabilization effect of stabilizing agent GX08 treating the marine and lacustrine soft soil in Hangzhou, andto investigate the adverse influence of organic matter on cementing soft soil, unconfined compressive strength (UCS) tests areperformed on stabilized soils. Test results indicate that organic matter significantly hinder the growth of the strength of stabilized soil,whereas stabilizing agent GX08 can effectively enhance the strength of the stabilized soil. The results show that the strength ofstabilized soil is well correlated with organic matter content as a form of quadratic function, and it is correlated linearly with cementcontent, and both are correlated as the form of logarithmic function with stabilizing agent GX08 content and curing time. The totalcement/water is applied to the establishment of the stabilized soil strength model. Based on the analysis of tests data, a predict model,considering the influences of organic matter content, cement content, stabilizing agent content and curing time on the strength ofstabilized soil, is proposed to predict strength development. Finally, the model is to be promoted to use, so as to verify theapplicability of the model.
