| 摘 要： | 大量的试验与研究结果均表明,梁式模型法适用于多桩薄承台设计,对于厚承台并不适用。通过对国内外桩基承台试验数据统计,确定空间桁架方法和梁式模型方法应用于承台的界限,也即如何定义"薄"承台和"厚"承台;并且通过对试验数据的数学统计,考虑承台底层纵筋对抗剪和抗冲切的有利作用,对梁式模型法的冲切和剪切公式进行了修正。

| Abstract: | Some experiments and researches on the behavior of pile caps have been reported in literatures both at home and abroad.These reports confirmed that the beam model is not suitable for design of thick pile caps but thin pile caps.On the basis of analyzing pile cap test data,the application ranges of strut-and-tie model and beam model have been defined.Meanwhile,taking the contribution of longitudinal reinforcement to the shear strength into account,some modification to the one-way and two-way shear formulaes ... |
