摘要
根据试桩资料和有限元数值模拟,对广泛应用于大型桥梁的大型灌注桩(桩长大于50m、直径大于800mm)的一些特殊性质进行了研究。这些特殊性质体现在大型灌注桩在桥梁建设中应用的广泛性和特殊意义、持力层的作用、持力层的选择、有效桩长等。研究结果对大型灌注桩的实际应用会有指导意义。
With reference to the trial piling data and FEM simulation, this paper makes a study of the characteristics of large bored piles (pile length >50 m, pile diameter >800 mm) that are widely used for major bridges. The characteristics of the piles in question are of universality and special significance in bridge construction, and include function of bearing layer, selection of the bearing layer and effective pile length. The findings of the study herewith may serve as guidance to the practical application of large bored piles.
