桩侧土体变化对预应力混凝土管桩性能影响

预应力混凝土管桩是一种新型的预制桩型。该桩力学性能比传统的混凝土桩要优越，正广泛地用于南方软弱土层工程中。本文根据现场施工资料，并采用非线性有限元基本原理，对管桩进行合理计算模型、模拟预应力混凝土管桩的桩侧土的传力机理，对影响承载性能的桩侧土体进行了详细的分析、计算和研究，为以后的建筑工程中采用此类管桩的运用提供参考依据。

Pile-side Soils Changes on Performance of Prestressed Concrete Pipe Pile

The prestressed concrete pipe pile is a new pile ty-pe. The pile mechanical properties than conventional concrete pile to be superior, are widely used in the soft soil engineering. According to the data of construction site, and the principle of＆amp;nbsp;nonlinear finite element, the pile reasonable modeling simula-tion, force transfer mechanism of prestressed concrete pipe pile, the soil factors measured bearing capacity of prestressed conc-rete pipe pile pile, is analyzed, calculated and studied in detail, for the later construction used in feasibility and economy of this kind of pipe to provide reference.
