［摘要］北京汽车博物馆工程上部结构空旷，室内设有大跨双曲钢桥，屋顶为大跨度空间钢结构，结构对各点沉降变形要求非常严格。地基大部分为深15m的建筑垃圾，局部为卵石。经过多种方案比较，确定了最佳的复合地基处理方案，提出了在深度较大、深浅不均的建筑垃圾坑上设计较为空旷建筑的切实可行的处理方法。

Abstract:The structure of Beijing AUTO EXPO is clear and the columns are sparse. There is large-span steel bridge between floors and the roof structure is large-span spatial steel structure. Critical demand is raised for the sedimentation of foundation. Most part of the foundation is building garbage and the rest is gravel cobble. Through comparison on several schemes of composite fouodation, the best one is chosen. The method of large-span structure on the foundation which is composed of deep building garbage is raised.
Keywords:composite foundation; building garbage; cooperative analysis; dynamic compaction; rammed pile
