摘要
本文论讨了3个问题:(1)利用Brauns的解建立了单桩载荷试验与复合地基载荷试验的碎石桩承载力关系,并以3个工程实测结果进行了验证;(2)以9个工程70组实测资料,分析了应力分担比n值的变化规律性;(3)报道了瑞利波法检测地基的机理及工程实例。
This paper discusses three problems: (1)relationship of bearing capacity of stone columns during loading tests of single stone columns and composite ground is established according to Brauns' solution and is verified with field measurement results of 3 engineering projects; (2)values of n are analysed according to field measurement data of 70 groups of 9 engineering projects and n=2.5 for sandy subsoils and n=3.5 for clayey subsoils are suggested; (3)principle of measurement of ground properties with Rayligh wave method applied to 4 engineering projects.
