青州博物馆新馆地基基础设计

Foundation design of the new Qingzhou Museum

详细分析了场地西侧南北向冲沟内欠固结人工回填土的特点,给出了SDDC工法地基处理的方法和施工流程。对比了两种地基基础方案的优缺点,给出了地基基础形式的选择过程。根据单桩抗压极限承载力的估算结果分析了冲沟范围内人工回填土及后注浆技术对单桩抗压承载力的影响。对抗压桩和抗拔桩的荷载工况进行了分析和给出了桩数的确定过程,分析了本工程所采取的抵抗地震水平力的一些措施。针对超长基础结构,文中给出了相应的处理措施。

This paper analyzed in detail the characteristics of under consolidated artificial backfill in the North-South gully on the west side of the site,and gived the method and construction process of SDDC.The advantages and disadvantages of the two foundation schemes were compared,and the selection process of foundation form was given.According to the estimation results of the ultimate compressive bearing capacity of the single pile,the influence of artificial backfill and post-grouting technology on the compressive bearing capacity of the single pile in the gully range was analyzed.This paper analyzed the load cases of compressive pile and tension pile,gived the determination process of the number of piles,and analyzed some measures taken in this project to resist the seismic horizontal force.For overlong foundation structure,the corresponding treatment measures were given in the text.
