The Rational Design And Seismic Studies Of The Suspension Bridge At Sea Anchor

In this paper,To the background of Dalian Xinghai Bay suspension bridge,the first sea anchor in china,the main work is as follows:1.Review the history of suspension Bridges and the sea anchor research status.2.For the development history,design idea calculation of research of the sea anchor to research.For this suspension bridge anchor,design concept, construction method is introduced for future sea anchor pieces of the design of the suspension bridge with favorable experience.3. Through grouting experiments,litre plasma experiment, strength experiment, the experiment can ensure the slurry groped to success.Based on the caisson gravel sliding experiment, the friction coefficient between bed can get.For future design and research to provide favorable test data.4. At sea anchor of structure form is determined, structure and stability analysis is key to shift. This paper analyses the anchor of structure in the cable force,calm water pressure the displacement and stress condition, and analysis of depth and friction factors on the influence of the displacement. The calculation results meet code requirements.5.For the sea anchor of caisson basis,the seismic performance has a tough demands. This paper adopt additional quality research in earthquake and dynamic water pressure of the displacement and stress condition, and the depth and friction factors on the influence of the displacement.For future design and research to provide favorable data.In this paper,the reasonable design of parameters and construction method and some experiments,the application of the finite element was used to study the sea anchor of displacement and stress state,the sea anchor pounds and caissons of design and construction of foundation provide references, and anchor pieces of soil structure of nonlinear seismic response analysis to ensure the sea anchor pieces of foundation engineering stability and security.
