超长桩单桩荷载传递刚度法函数解分析

荷载传递是超长桩工作特性的重要内容.建立并拟合分析桩土传递的函数模型,分析了桩侧土剪切模量、桩身混凝土模量、长径比、桩长和桩径等不同参数对超长桩承载性能的影响,运用有限元分析软件通过计算实例分别分析了桩长、桩径、土体粘聚力c值、桩侧土体刚度、桩端土体刚度对桩基承载性能的影响程度.

Stiffness Method Function Solution Analysis of Single Pile Load Transfer of Super-Long Pile

Load transfer is an important content of the operating characteristics of super-long pile. This paper establishes function model of pile-soil transfer and makes the fitting analysis, analyzes the effects of different parameters including pile lateral soil modulus, shear modulus, pile body concrete length to diameter ratio, pile length and pile diameter on the bearing performance of super-long pile, and the influ- encing degree of pile length, pile diameter, c value of cohesive force of soil, pile side soil stiffness and pile tip soil stiffness on the bearing performance of the pile base by using the software of finite element analysis to calculate the example.
