摘要:

采用Boussinesq和Geddes解的联合求解方法,得到了考虑复合地基中桩顶和桩间土顶荷载时复合地基中任意深度处附加应力的分布情况;并根据柔性桩、桩间土和复合地基沉降关系.得到了带垫层柔性桩复合地基有效桩长计算方法.试验和计算结果对比表明:由于考虑了桩间土顶压力、桩身刺入量变形等因素对复合地基有效桩长的影响,有效桩长计算结果同现场实际情况比较吻合.

Abstract:

The joint solution method of Boussinesq and Geddes solution is used to obtain the distribution of additional stresses at any depth in the composite foundation considering the pile top and the soil top load between piles in the composite foundation. And according to the settlement relationship of flexible pile, interpile soil and composite foundation. The effective pile length calculation method of flexible pile composite foundation with cushion is obtained. The comparison of test and calculation results shows that the effective pile length calculation results are consistent with the actual situation of the composite foundation due to the influence of soil top pressure between piles and the deformation of pile penetration amount on the effective pile length of the composite foundation.
