水平荷载下X形桩承载特性简化计算方法
Simplified calculation method for bearing capacity of XCC pile under lateral load
摘要
Abstract
XCC pile has many technical features, such as large units material pile-soil contact area, high pile lateral friction, etc. However, there is no lateral bearing capacity calculation method for XCC pile, which limits its wide application in engineering. Based on conventionalp-y curve calculation method (which is suitable for circular pile), and considering the cross section special-shaped effect of XCC pile, the simply theoretical calculation method for XCC pile under horizontal load were established. The reliability and feasibility of theoretical model established in this paper were verified by comparing with large-scale model test results. Finally, factors influencing (such as, pile length, soil properties,p-y curves and loading grades, etc.) were discussed. The results show that the lateral bearing capacity of XCC pile can be estimated by using conventionalp-y curve and reduction factor of cross section shape.关键词
