摘要
以苏州润华环球大厦深基坑工程为研究对象,通过技术和经济比较合理的选择支护方案,并以Z_SOIL.PC专业岩土程软件为工具,分析各工况下围护结构的受力变形特性及周围土层位移。结果表明,采取土钉墙和围护桩+二道内支撑的方案相对于围护桩+三道内支撑方案在受力性能上差别不大,但是技术经济效益却很明显,对于基坑支护的设计具有一定的指导意义。
Based on deep foundation project in Runhua Global Building in Suzhou,authors make reasonable choice of support scheme by technologic and economic comparison.They make analysis on bearing and deforming behavior of retaining structure and displacement of around soils under several working conditions with Z_SOIL.PC.The results show that there is little difference on the mechanical behavior between the scheme of soil nailing wall and fender piles with two layers of supports and the scheme of fender piles with three layers of supports.However,the first scheme has brought the obvious technology economic efficiency which offers reference to foundation supporting design.
