摘要

根据控沉疏桩理论，探讨了带帽PTC型刚性桩在高速公路深厚软土地基处理中的适应性。为了掌握带帽PTC管桩复合地基的作用机理，分析了其承载能力、荷载传递、桩侧土压力、桩侧摩阻力、桩土荷载分担比及桩-土应力比等力学性状，并进行了带帽和无帽单桩复合地基现场足尺试验，对试验结果进行了深入地分析和研究。试验结果能为带帽PTC管桩复合地基理论研究提供合理的试验依据，并指导工程设计。

Abstract

According to the control settlement and sparse piles theory

the applicability of prestressed concrete(PTC) piles with cap in the profundity soft soil ground treatment of a highway has been discussed. The spot tests of single pile with cap composite foundation and single pile without cap composite foundation have been done in order to master its working mechanism and investigate the mechanical behavior of load-bearing capacity

load transfer

earth pressure beside pile

the skin friction of pile

sharing of load and pile-soil stress ratio of PTC pile with cap composite foundation. The test results have been analyzed and researched deeply; and some useful conclusions are drawn

by the experiment

which can provide reasonable test base for us to study the theory of PTC pile with cap composite foundation and may be a guide to design control settlement and sparse piles composite foundation.
