摘要考虑了桩的刚度之间的耦合,桩帽,和列的一种数值方法已被开发用于群桩支承柱的响应分析,特别注重考虑桩帽的灵活性。这是一种采用 t–z/q–z 和 p–y 曲线的负载转移用于单桩的分析的方法。有限元法是用来结合桩的刚度与帽和列的刚度。发达国家的数值方法被核查与群桩其他数值方法的比较结果。通过比较研究,已经发现在一组中的单个桩上的最大负载是受桩帽的灵活性高度。在目前的分析桩帽的横向载荷和弯矩的预测,比在FBPier3.0更为保守,它确定了更大的横向载荷和弯矩各种桩帽的厚度。

1、简介
桩常用于团体支持的桥梁结构。有很多分析和数值群桩的设计方法。这些方法可以创分为三种不同类型:(1)当量的人员单桩方法[1 - 5],(2)弹性的方法[6 - 9],和(3)一般三维负载转移方法(10 - 14)。
第一种类型的方法是基于一个无依据的分析单个桩结合组有效率因素,或组放大系数代表的桩土桩互动和桩帽的相互作用。在简单的这种方法,即用一个电子表格来计算的设计参数,是其主要优点。然而,这方法有一定的限制,它只适用于均匀间隔的群桩且不大于近似方格的安排,不提供荷载分布在一组沿桩深度[5]。第二个类型的方法是一个连续的方法,那是一个三维线弹性桩周围土壤连续体相互作用因子的方法[6]明德林的解决方案,并直接连续模型[8]通常包括在这一类。应当指出的是,这种方法最初是一个弹性的方法,虽然已经开发了多种变型,允许土壤分层模型、桩土滑移、三维的几何形状等。源'自^优尔;文,论`文'网]www.youerw.com
