新型悬浮施工栈桥的力学性能
Mechanical properties of new suspension construction bridge
摘要
Abstract
In order to verify the engineering feasibility of the proposed suspension construction convenient bridge concept,the mechanical properties of the standard segment of the suspension construction convenient bridge were studied.Through the design research and model experiment on a standard segment of suspension construction bridge,the size and distribution position of external load were controlled,and the vertical displacement of the structure under different working conditions,the deformation characteristics of the buoy and the stress distribution of the anchor cable system were studied.The research results show that the segment model does not have large structural deformation under different loading conditions,and there is no inclination under eccentric loading.The maximum deformation under central loading is 4.5 mm,and the maximum deformation under eccentric loading is 7.6 mm,which are all less than the deformation value under the maximum allowable stress of the temporary construction trestle.It verifies that the suspension construction bridge has engineering feasibility.关键词
