| 摘 要： | 利用基于荷载传递函数法和有限层法基础上的数值分析法对承受负摩阻力的单桩荷载性状进行了分析,研究了填土高度、桩顶荷载、桩端土刚度对桩身轴力、桩底和桩侧阻力的发展及桩沉降的影响,研究发现软土地基中,0.5的填土高度能导致负摩阻力较充分地发挥,承载负摩阻力的端承型桩与摩擦型桩一样,承载力需综合沉降确定。

| Abstract: | Analysis of bearing performance of pile under negative skin friction is done by numerical simulation combining load transfer method and finite layered method.The influence on development of side and end resistance,axis load and settlement of pile by filling sickness,soil stiffness of pile bottom and load upon pile top is studied.It is found that 0.5 m thick soil filling can make negative skin friction most be developed,and the bearing capacity of frictional pile as well as end-bearing pile under negative sk... |
