基于支墩坝和斜拉桥技术的斜拉坝模型

Cable-Stayed Dam Model Based on Buttress Dam and Cable-Stayed Bridge Technology

为促进坝工技术的创新和发展,尝试将斜拉桥的先进技术运用在支墩坝中,提出了斜拉坝模型。并从历史来源、主要分类形式、温控、受力特性、耐震性、经济性、导流优势、岸坡稳定、坝肩连接形式、大坝加固、景观效果等方面对斜拉坝模型做了简要介绍,并与斜拉板桩码头结构模型进行对比,对采用CFRP拉索、自密实混凝土支墩、高强钢挡水结构等技术在斜拉坝模型中的应用进行展望,斜拉坝是一种新的坝工模型,具有较好的应用前景。

In order to promote the innovation and development of dam engineering technology,this paper tries to apply the advanced technology of cable-stayed bridge to buttress dam and proposes the model of cable-stayed dam.A brief introduction is made to the cable-stayed dam model from the aspects of historical origin,main classification forms,temperature control,mechanical characteristics,seismic resistance,economy,diversion advantage,bank slope stability,abutment connection form,dam reinforcement,landscape effect and so on.The cable-stayed dam model is compared with the model of cable-stayed sheet pile wharf.The application of CFRP cable,rock-fill concrete support piers and high strength steel water retaining structure in the model of cable-stayed dam is prospected.The cable-stayed dam is a new dam engineering model and has good application prospects.
