| 摘 要： | 北京市区存在许多杂填土回填地基,主要是人为挖沙等原因形成。该部分地基回填成分复杂,既有建筑垃圾、工业垃圾和生活垃圾,又有几者的混合,而且此种地基成层薄厚不一、具有湿陷性和负摩阻力、均匀性差、承载力低、压缩性高、不确定性成分大且无规律性,所以此种地基必须根据实际情况综合确定经济、适合和可靠的优化处理方案,进行地基处理后才能作为建(构)筑物地基。结合西南四环珠江绿苑工程,论述北京市区杂填土地基处理组合型(综合)技术,并通过试验结果和沉降观测资料分析多种地基处理技术相互结合在高层建筑中应用的效果,并得出结论。

| Abstract: | A lot of mixed backfill foundation exist in Beijing city mostly because of the excavation of sand.The composition of this kind of foundation is complex,including structural garbage,industrial garbage and living garbage.The optimal ground treatment methods must be adopted in this kind of foundation for its difference of thickness,negative friction,remarkable difference of uniformity,low bearing capacity,high compressibility,high indeterminacy and nothing of regularity.This kind of foundation is usefull in the buildings only after ground treatment.Taking Beijing Pearl River Luxury Apartment as an example,the component type foundation treatment of Beijing urban mixed fill is dissertated.The effect of the treatment is analyzed by the test and the data of settlement in high-rise building.The elementary conclusion is educed. |
