摘要
南宁盆地圆砾颗粒组成均匀,胶结紧密,分布连续,是较理想的桩端持力层。传统的承载性能的确定方法不能准确地揭示其密实程度及桩基承载潜力,该文通过实验得出了确定桩的承载性能,宜采用超重型圆锥动力触探试验与桩基静载试验综合确定。
In Nanning basin, the circular-gravel layer is an ideal bearing stratum of piles, because of it＇ s homogeneous particle composition, compact cohesion and continuous distribution. The compactness of circulargravel layer and latentral bearing capacity of piles can not be precisely evaluated with traditional determination methods, but do it with superheavy dynamic sounding （SDS） and pile static loading test.
