夯实水泥土受力性能试验研究及工程应用

Experimental research on mechanical properties of compacted soil cement and engineering application

通过对水泥土试块无侧限抗压强度的试验研究,分析了含水量、水泥掺量和养护龄期对黄土状粉质黏土水泥土桩无侧限抗压强度的影响,建立了水泥土试块无侧限抗压强度与养护龄期和水泥掺量的关系式,为寻求更加经济、合理的施工配合比和参数提供了理论依据。用试验成果指导某工程实践,取得了较好的经济效益。

The influence of water content, cement content and curing age on unconfined compressive strength of loess soil cement pile was analyzed through experimental study on unconfined compressive strength of soil cement test block. Relational expression between unconfined compressive strength of soil cement test block and cement content, as well as curing age was established. The results provide theoretical basis for more economic and rational mixture ratio and parameter for construction which have been successfully used to guide a project and acquired the favorable economic benefit.
