| 摘 要： | 以长洲水利枢纽三线四线船闸为例,介绍了一种适用于受场地条件限制的新型导航墙结构——高桩承台+预应力锚索的复合结构。该结构通过高桩承台和预应力锚索的联合作用,有效地改善了桩基的内力条件,控制了结构的变形。在场地条件受到限制、使用荷载大、常用结构不适宜时,该结构具有较好的参考应用价值。

| Abstract: | Taking the third line and the fourth line ship locks of Changzhou hydro-junction for example,this article presents a new navigation wall structure suitable for site conditions limited,namely the composite structure of elevated pile caps and prestressed anchor.This structure improves effectively the condition of the pile foundation internal forces and controls the deformation of the structure through jointing actions of elevated pile caps with the prestressed anchor.When the site conditions are limited,using loads are large and common structures are not appropriate. |
