为获取改良土工程设计参数,对李渡红土加入掺合料石灰后,进行了有荷载条件模拟干湿循环过程的试验研究,得到了其胀缩变形变化规律,指出有荷条件下,不同配比的试样随干湿循环次数增多其相对和绝对胀缩率都在逐渐减小;石灰量在一定范围内,土样的绝对和相对胀缩率随土料中含石灰量增多而减小。
In order to get the design parameters of improved soil engineering, the limestone of limestone is added into limestone of LiTu, the experimental research on the process of simulating wetting and drying process under load condition is carried out, and the law of its deformation and shrinkage is obtained. It is pointed out that under different loading The relative and absolute expansion and contraction rates of the samples decrease with the increase of the number of cycles of wet and dry cycles. The absolute and relative expansion and contraction rates of soil samples decrease with the increase of lime content in the soil with the lime content within a certain range.
