| 摘 要： | 通过流动度测试、无侧限抗压强度试验来研究含泥量对砂质土流态固化处理效果的影响。同时基于响应面法，以水灰比为2∶1的混合样为例，分别建立了含泥量与流动度、无侧限抗压强度的关系模型，并分析其影响规律。结果表明，含泥量等因素均对流动度、无侧限抗压强度产生影响；根据试验结果拟合得到的模型显著，存在某个含泥量，使得流动度和强度均存在峰值。

| Abstract: | Fluidity tests and unconfined compressive strength tests were carried out to study the influence of mud content on the curing effect of sandy soil. Based on the response surface methodology, the relationship models of mud content with fluidity and unconfined compressive strength were established for mixed samples with a water cement ratio of 2:1, and the influential laws were analyzed. The results show that the mud content and other factors affect the fluidity and unconfined compressive strength. The model obtained by fitting the test results is significant, and there is a certain mud content, which makes the fluidity and strength both have peak values. |
