摘要: 依托某商业综合体主楼基础设计,通过技术资料研究,根据结构层数、荷重分布等特点,充分考虑场地土层分布性状与物理力学特性、沉桩可能性及经济优势等因素,对多种可行性基础方案的技术和经济性进行比较,选择最优方案,在满足工程承载力要求的同时,又能较大幅度地减少工程造价,具有较高的经济效益,设计思路可供同类工程参考。

Abstract: A foundation type selection comparison was performed during the design for the main structure of a commercial complex. Various factors, such as, structural loading distribution, structural story arrangement, subsurface soil stratigraphy, and physical and mechanical properties of subsurface soils, constructability of different pile types and their cost, are compared. The optimized foundation type, which meets the axial bearing capacity and also is the most cost effective solution, is selected.
