| 摘 要： | 以控制桩帽间土体沉降量在工后沉降量标准范围内为目标,提出带帽控沉疏桩复合地基设计的思路和方法.采用调整桩体中心间距或桩帽尺寸等措施,以改变复合桩土应力比来进行带帽控沉疏桩复合地基设计.基于弹性理论和等沉面思想,不考虑复合桩体自身压缩变形量,简化了带帽刚性桩复合地基复合桩土应力比隐式计算公式,得到了按桩帽间土体沉降计算模...

| Abstract: | The design idea and method of composite foundation of rigid pile with cap were put forward based on controlling the settlement deformation of the soil beside pile caps in the range of post-construction settlement criterion.Adopting the measures of adjusting the distance of two caps or size of pile cap,the composite pile-soil stress ratio was changed for the design of composite foundation of capped sparse pile to control settlement.On the basis of elastic theory and the idea of equal settlement section,negle... |
