载体桩在苏州地区的适用性分析

Feasibility of the Application of Ram Compacted Columns with Enlarged Base in Suzhou

选择合适的桩型对工程经济性至关重要,结合大量工程资料,对苏州浅层第四纪地层物理力学指标进行了统计分析,对载体桩适宜的持力层进行了总结,并对各土层承载力进行了分类分析。结合已实施的工程案例,对载体桩的适用性进行了技术经济对比,表明载体桩在苏州地区具有较广泛的适用性。

The selection of pile/column types is critical to the project cost control.The physical and mechanical properties of the shallowly deposited Quaternary soils in Suzhou area are statistically analyzed.The properties of the bearing strata that are potentially suitable for the ram-compacted columns with enlarged base are summarized.A cost comparisons of the ram-compacted columns with enlarged base is provided for the various practical projects.It is concluded that the application of the ram-compacted columns with enlarged base in the Suzhou area is feasible.
