摘要

采用静载荷试验和ABAQUS有限元模拟相结合的方法进行了新型带肋预应力管桩承载性能的研究。对外径相同（500 mm）的直型桩与带肋桩的现场静载荷试验结果进行了对比研究，结果表明，带肋桩的极限承载力较直型桩提高13.10%。分析了肋部厚度、肋部间距等桩型参数对新型带肋管桩承载性能的影响。提出新型带肋预应力管桩极限承载力的建议计算公式，为今后新型带肋预应力管桩的大规模应用提供参考。

Abstract

The bearing behavior of a new type of prestressed pipe pile with rib (the pile with rib for short) via ABAQUS finite element simulation and in-situ static load test. The comparison between the in-situ static load test of the pile with rib and the common pile with the same outer diameter (500 mm) shows that the ultimate bearing capacity of the piles with rib is 13.10% higher than that of the common piles. The influence of the pile parameters

including the thickness of the rib and the spacing between ribs

on the bearing capacity of the pile with rib is studied. Moreover

the design formula for bearing capacity of the pile with rib is suggested. The formula will provide an important reference for the large scale application of the new type of prestressed pipe pile with rib.
