【摘要】：為了驗(yàn)證固化劑GX08加固杭州海湖相軟土的效果及考察有機(jī)質(zhì)對(duì)水泥固化的不利影響,對(duì)固化土的強(qiáng)度特性進(jìn)行了試驗(yàn)研究。結(jié)果表明,有機(jī)質(zhì)的添加會(huì)顯著阻礙固化土強(qiáng)度的增長(zhǎng),而固化劑GX08能有效增強(qiáng)固化土的強(qiáng)度;固化土強(qiáng)度與有機(jī)質(zhì)含量存在二次函數(shù)關(guān)系,與水泥摻量呈線性關(guān)系,與固化劑GX08摻量和齡期都以對(duì)數(shù)函數(shù)的形式相關(guān);將總灰水比C/W用于固化土強(qiáng)度模型的建立,通過對(duì)試驗(yàn)數(shù)據(jù)的分析與整理,建立了同時(shí)考慮固化土中有機(jī)質(zhì)含量、水泥摻量、固化劑摻量和齡期影響的固化土綜合強(qiáng)度預(yù)測(cè)模型。最后對(duì)模型進(jìn)行了推廣使用,驗(yàn)證了模型的適用性。
[Abstract]:In order to verify the effect of curing agent GX08 on strengthening Hangzhou Haihu soft soil and to investigate the adverse effect of organic matter on cement curing, the strength characteristics of solidified soil were studied. The results show that the addition of organic matter can significantly hinder the growth of the strength of solidified soil, and the curing agent GX08 can effectively enhance the strength of solidified soil, and there is a quadratic function relationship between the strength of solidified soil and the content of organic matter, which is linearly related to the content of cement, and is related to the content and age of curing agent GX08 in the form of logarithmic function. The total ash-water ratio C 鈮，
