摘要
水泥土目前被广泛的应用于水利工程、建筑工程以及道路工程,但由于水泥土抗压强度的影响因素很多,需要作大量的实验,费时费力。该文在前人试验工作的基础上,通过曲线拟合方法,定量分析了水泥土抗压强度与土质、水泥掺入量、龄期等的关系,得到了水泥土强度经验公式。该公式在南通人防大厦基坑锚拉水泥土挡墙支护设计中得到验证,具有一定的理论意义和实用价值。
Cement-soil has been widely applied to hydraulic engineering, architectural engineering as well as highway engineering at present, but it must take a lot of time and energy to do cement-soil compressive strength experiment, because there are many influential factors on cement-soil compressive strength. Based on previous works, by means of nonlinear curve fitting methods, this paper quantitatively analyzes the influence of soil types, the mixed quantities of cement and ageing etc. on the cement-soil compressive strength. An empirical formula of cement-soil compressive strength is established. And it is certified by the design with cement-soil retaining wall and anchor for foundation pit in Nantong civil air defense building. It has certain theoretical meaning and practical value.
