摩擦桩的荷载传递及承载力的一些问题

本文首先讨论桩承载力的主要影响因素,分析桩的荷载传递机制,描述各类荷载传递函数的型式,介绍桩侧摩阻力和端阻力的测定方法及实测结果。接着,分析成桩方法对承载力的影响。最后,对钻孔灌注桩的下沉,失稳和承载力变化进行讨论。

Some Problems Concerning Load Transfer and Bearing Capacity of Friction Piles

In this paper, the main influence factors upon bearing capacity of friction piles are discussed, load transfer mechanism of piles is analyzed, various kinds of load transfer functions are described, determination methods for lateral friction and tip resistance of piles are introduced, and some field measuring results are presented. Then, the effects of piles driving methods on bearing capacity are analyzed. Finally, the subsidence, unsteady and bearing capacity variations of bored concreting pile are discussed.
