摘要: 为减少高填土对邻近主体建筑的不利影响,减沉路堤桩在辰山植物园工程中得到了广泛应用并在高填土与建筑挡墙之间发挥了隔离缓冲的重要过渡功能。结合现场复合桩基竖向极限抗压承载力静载试验、桩顶反力和土压力分布测试及沉降影响计算分析等要素,阐明该工程减沉路堤桩的设计方法及特点。通过系统研究路堤桩数值计算中结构参数的取值,分析相应的水平位移及桩身弯矩容许值,提出合理的填土和桩基施工工序。Abstract: In order to reduce the the adverse impacts of the tall fill on the nearby buildings,the embankment piles were widely used in Shanghai Chenshan Botanical Garden and played a significant role between major structures retaining wall and the tall fill.This paper introduced special design technology measures of the test piles and discussed engineering features of the experiment of composite piled foundation,pile-soil ratio testing and settlement analysis.The design parameters were studied carefully so that the precise possible displacement and bending moment of the single pile could be obtained.Based on the accurate reaction of the pile stress and deformation in various conditions by three-dimensional finite element software,it was proposed reasonable fill and construction sequences of the pile foundation.
