锚桩反力梁慢速维持荷载法桩基静载试验研究

On Pile Foundation Static Loading Test with Anchor Pile Reaction Beam Slow Maintenance Loading Method

桩基静载试验采用接近于通过竖向抗压桩的实际工作的试验方法,比较准确地反映单桩的受力状况和变形特征,确定单桩竖向抗压承载力,对工程桩的承载力进行抽样检验和评价。结合京沪高速铁路基桩静载荷试验,详细阐述了锚桩反力梁慢速维持荷载法桩基静载试验工艺。

Static load test of pile foundation is closer to the test method of vertical compressive piles in actual work.It reflects the force and deformation characteristics of single pile with a relative accuracy,makes out vertical compressive bearing capacity of single piles,tests and evaluates the bearing capacity of engineering piles by sampling.Combined with foundation pile static loading test in Beijing-Shanghai High-speed Railway,this paper expounds in detail the technique of pile foundation static loading test with anchor pile reaction beam slow maintenance loading method.
