［摘要］北京汽車博物館工程上部結(jié)構(gòu)空曠，室內(nèi)設(shè)有大跨雙曲鋼橋，屋頂為大跨度空間鋼結(jié)構(gòu)，結(jié)構(gòu)對(duì)各點(diǎn)沉降變形要求非常嚴(yán)格。地基大部分為深15m的建筑垃圾，局部為卵石。經(jīng)過多種方案比較，確定了最佳的復(fù)合地基處理方案，提出了在深度較大、深淺不均的建筑垃圾坑上設(shè)計(jì)較為空曠建筑的切實(shí)可行的處理方法。

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
