【摘要】 本文通过某电厂4根大直径扩底灌注桩的水平承载力试验,从实测的桩身应变,分析了浸水前后桩的水平承载力性状,探讨桩顶垂直荷载对桩水平承载力的影响,并将水平静载试验的实测值与理论计算值作了比较,提出了适用于厚层黄土中大直径灌注桩的计算方法。更多还原

【Abstract】 In this paper, the lateral load-bearing capacity of a pile in thick loess is described by testing four large diameter belled piles. According to strains of the pile shaft, obtained from practical tests, the lateral load-bearing capacity of a pile before and after inundation is analysed and the effect of vertical load on the lateral load-bearing capacity of a pile is approached. By comparison of testing data with calculated results, the calculating method for the lateral loadbearing capacity of a large diameter pile cast-in-place in thick loess is presented.更多还原
