高速公路大型管桩复合地基载荷试验研究

Study on Static-Load Test of Compound Ground with Tubular Piles of Expressway

预应力管桩在建筑工程中应用已很广泛,具有施工便捷、显著降低施工工期和工后沉降特别是减小差异沉降的优点,在公路工程中的应用也正得到日益重视,但很多问题还有待于开展深入的试验和理论研究。本文阐述了高速公路大型管桩复合地基载荷试验的工程条件、试验过程和试验结果,并对试验结果作了一些分析,以推动管桩复合地基在公路工程尤其是高速公路中的应用。

Based on the virtues of prestressed tubular piles, this paper expounds the engineering condition, test process and test results of compound ground with tubular piles of expressway. These are expected to drive the application of compound ground with tubular piles to expressway in order to reduce the settlement after construction.
