预应力混凝土管桩复合地基静载试验研究

Research on Static Loading Test of Pre-stressed Concrete Tubular Pile Composite Foundation

预应力混凝土管桩近年来在工程建设中得到了广泛应用,预应力混凝土管桩复合地基能有效改善地基土受力状态,提高地基承载力。通过一大型预应力混凝土管桩复合地基试验研究,分析其受力和沉降特性,为工程设计、施工及管理人员提供一些帮助。

Pre-stressed concrete tubular piles have been used in some projects in recent years. Pre-stressed concrete tubular pile foundation can improve the force-bearing conditions of foundation soil and enhance bearing capacity of foundation. By the test of a large-scale one its characters of bearing-force and settlement are researched and analyzed, which will offer some help to project designers, constructors and managers.
