摘要
文中以坐落于深切河谷山区的某斜拉桥为例,基于静载试验方法,对叠合梁斜拉桥结构的刚度与强度进行了评估与研究。结合桥梁的特点进行有限元理论计算,确定了静载试验的工况、测试截面与测点布置。静载荷载试验结果表明,在设计荷载作用下,斜拉桥的主塔、主梁和斜拉索等结构均处于弹性工作状态,结构强度和刚度满足设计要求。
Taking a cable-stayed bridge located in a deep valley as an example,based on the static load test method,the stiffness and strength of the structure of the superimposed beam cable-stayed bridge in a deep valley were evaluated and studied.Based on the characteristics of the bridge,the finite element theoretical calculation is carried out to determine the static load test condition,test section and measuring point layout.The static load test results show thatu nder the design load,the main tower,main beam and stay cabl eof the cablestayed bridge are in the elastic working state,and the structural strength and stiffness meet the design requirements.
