预应力锚杆无底扶壁结构构造设计

Approach to Structure Design of Unbased Buttressed Structure with Prestressing Anchors

预应力锚杆无底扶壁结构是重庆市南岸滨江路护岸工程中首次提出并得到良好应用的一种新型结构。该结构主要由立板、肋板和防滑齿墩及预应力锚杆体系等组成,其结构构造简单,受力明确,施工方便,工程造价较低,是一种适用于岩石地基,尤其适合于岸坡地形陡峭、不能进行大面积开挖(或进行大面积开挖不经济)地段的良好新型护岸结构。文章详细介绍了该结构的构造设计特点和设计基本要求。

The unbased buttressed structure with pre-stressing anchors is a type of new structure,which is first successfully used in the revetment works of Chongqing Binjiang Road.It consists of upright plate,ribbed plate,anti-slide pier and pre-stressed anchor.The new structure has some obvious advantages,such as simply structure,clear stressed state,easy construction and low construction cost.It is a better and advanced revetment structure,which adapts to rock ground,especially when slope is steep and where the wide excavation is not available(or the excavation is not economical in wide area).In this paper,the detailed design characteristics and the principle requirement of design is also provided.
