场地形成的水泥土的劣化室内模拟试验
Laboratory Simulation Experiment on Deterioration of Cement Stabilized Soil in Site
摘要
Abstract
The effect of curing time and cement content on the cement stabilized soil deterioration which formed in Qingdao Jiaozhou bay marine soft soil site is studied by laboratory simulation experiment. The deteriorated depth is defined according to the features of penetration resistance and penetration depth curve. It is indicated that the deterioration extends quickly under seawater environment, and the deteriorated depth becomes deeper with the increase of curing time. With the increase of cement content, the strength of cement stabilized soil increase obviously, at the same time, the deteriorated depth reduce significantly. The concentration of Ca2+ in the cement stabilized soil has a trend to decrease from deep to shallow,the concentration of Mg2+ gradually decreases with increasing depth.关键词
