摘　　要：壁板桩(barrette) 是用来承受建筑物上部结构荷载的单段矩形截面地下连续墙。由于其比表面积和抗弯刚度比传统的圆形截面桩大, 有利于充分发挥桩侧摩阻力和水平抗力, 提高竖直和水平承载力。近年来, 这种桩型在国内外已经越来越广泛地应用到高层建筑、高架路和立交桥以及重型和大型(比如输电线塔) 基础工程中。本文回顾了壁板桩的应用与研究现状, 内容涉及壁板桩的施工效应、承载性能、桩身摩阻力的发挥特性以及施工效应对承载特性的影响等。Barrette refers to a single rectangular diaphragm wall panel, which is employed to carry the loads from superstructures. Since a barrette has a higher specific surface and a greater flexural rigidity than a circular pile, both vertical and horizontal shaft resistance can be fully mobilized, resulting in a higher capacity. Over the years, barrettes have been widely used as the foundations of high-rise buildings, viaducts, flyovers, and heavy and large-size infrastructure engineering (e.g., power transmission line towers). This paper presents a state-of-the-art review on various applications and investigations of barrettes,covering numerous aspects, such as,the installation effects, the load-carrying performance, the shaft resistance mobilization behavior, and the construction effects on the load-carrying behavior of barrettes.
