地处上海的某部华东物资供应办事处宿舍工程系两幢七层建筑,根据工程地质勘察报告场地表土层松散填土较厚,同时下卧淤泥质粘土层厚达13米多,压缩系数α_(1-2)=O.137厘米~3/公斤,孔隙比e=1.53,下面粘土层α_(1-2)=O.067厘米~2/公斤,e=1.19,若采用片筏基础或部分补偿的箱形基础或采用强夯法加固地基均不经济,计算沉降量较大。经研究后决定采用桩基。但若采用8米长的定型短桩,则单桩承载力较小,用桩很多且桩台较大,既
The dormitory project of a department of east China material supply office located in Shanghai is a two-story building. According to the engineering geological survey report, the topsoil of the site is loose and the thickness of the underlying silt clay layer is more than 13 meters. The compression coefficient α_ (1-2)=O.137 cm~3/kg, porosity ratio e=1.53, below clay layer α_(1-2)=O.067 cm~2/kg, e=1.19, if using a tablet foundation or The partially compensated box foundation or the reinforced foundation method is not economical and the calculated settlement is large. After research, it was decided to use pile foundations. However, if an 8-meter-long shaped short pile is used, the bearing capacity of a single pile is small, with many piles and large piles.
