摘要
在沿海港口区域加固淤泥及淤泥质饱和软黏土地基中有较多的应用,但其复合地基的设计理论尚不成熟,相关规程规范大多推荐试验的方法确定,对工程技术人员的初步设计造成不便。文中阐述了关于强夯碎石桩复合地基的多种理论及经验计算公式,并通过工程实例进行计算、分析及比较,得出比较适合本场地的复合地基承载力计算方法。
There are many applications in the reinforcement of silt and saturated soft clay foundation in coastal port area, but the design theory of composite foundation is not yet mature. Most of the relevant codes recommend the determination of test methods, which is inconvenient to the preliminary design of engineers and technicians. In this paper, various theoretical and empirical formulas for calculating composite foundation of dynamic compaction gravel pile are elaborated, and through calculation, analysis and comparison of Engineering examples, a method for calculating the bearing capacity of composite foundation suitable for the site is obtained.
