西安地区高层建筑地基基础方案采用桩基或复合地基较多,但在西安某些地区分布有工程地质性能良好的砂层,这类砂层地基承载力较高,压缩性较低。结合一栋96.15m高的33层高层建筑,通过原位平板荷载试验,从地基承载力验算、软弱下卧层验算、地基变形验算、沉降观测等方面分析得出,细中砂层作为高层建筑天然地基的地基持力层是可行的。 In Xi’an, the foundation plan of high-rise buildings uses many pile foundations or composite foundations. However, sand layers with good engineering geological properties are distributed in some areas of Xi’an. Such sand foundations have higher bearing capacity and lower compressibility. Combined with a 96.15m high 33-storey high-rise building, through the in-situ slab load test, from the calculation of foundation bearing capacity, checking of the soft underburden, foundation deformation checking, settlement observation and other aspects, the thin sand as a high-rise building Foundation of the natural ground bearing layer is feasible.
