摘要： 某拟建高层住宅楼群场区位于济南黄河冲积平原区，地层结构较为典型。在详细分析勘察取得的土层物理力学参数和建筑设计要求的基础上，通过规范公式计算和工程经验分析，评价各类地基基础方案的适用性，确定CFG桩复合地基和预应力混凝土空心管桩为较适宜的方案。可为济南市此类场区的建筑工程设计和经济分析提供依据，也可以为其他地区具有类似地层结构的建筑场区提供一定参考。

Abstract: A proposed highrise building is located in the typical subsurface strata of Jinan Yellow River alluvial plain. To select the appropriate foundation types for the various structures, a wide range of foundation types are evaluated based on the site specific conditions throughout the site geotechnical exploration results as well as the structural requirements of the building. It is concluded that the CementFly AshGravel (CFG) columns and the prestressed, precast reinforced concrete cylindrical pipe pile are the most appropriate foundation types. These foundation types provides an economical solution to the building construction in similar sites in Jinan.
