摘要
选取国内外4本常用碎石桩设计规范和文献,即美国联邦公路局规范、欧洲常用的设计参考文献以及国内的《建筑地基处理技术规范》《水运工程地基设计规范》,分别从碎石桩适用性分析、桩体材料级配要求、碎石桩设计参数等方面进行对比分析,并依托东帝汶Tibar港工程,对比采用不同规范和文献时碎石桩地基处理设计参数的确定过程。结果表明,适用性分析方法方面,欧美规范和文献提供了量化级配分析表,国内规范仅提供定性分析;桩体材料级配确定方面,欧美规范和文献均提供了典型级配曲线,而国内规范仅提供原则性规定;桩径和桩间距确定方面,欧美规范和文献均提供了经验关系设计图,而国内规范仅提供适用的范围值。
We select four commonly used domestic and foreign codes and reference for stone column design,i.e.,the codes of the Federal Highway Administration(U.S.),the common design reference in Europe,the Chinese codes Technical Code for Ground Treatment of Buildings and Code for Foundation Design on Port and Waterway Engineering,and conduct a comparative analysis from the aspects including the applicability of stone columns,the grading requirements of column material,and the design parameters of stone columns.In addition,this study compares the determination process of design parameters for foundation treatment of stone columns with the aforementioned codes and reference on the basis of the Tibar Port project in East Timor.The results reveal that regarding applicability analysis,the foreign code and reference provide quantitative grading analysis tables,while domestic codes only provide qualitative analysis.For the determination of column material grading,the foreign code and reference present typical grading curves,while domestic codes only introduce regulations in principle.For the column diameter and spacing determination,the foreign code and reference provide empirical relationship design diagrams,while domestic codes only give applicable range values.
