摘要
漠阳江特大桥主桥跨径布置为88 m+152 m+88 m,通过桥梁荷载试验评估其承载能力与工作状态。结果显示,在设计荷载作用下,静载试验所得桥梁挠度及控制截面应变校验系数满足规范要求,桥梁处于弹性范围内;桥梁竖向频率也略大于理论值;桥梁工作状态良好。试验为今后漠阳江特大桥的安全运营提供了必要的技术参数,也为同类型桥梁的鉴定提供重要的技术资料。
The span of the main bridge is 88 m+152 m+88 m,and the load-bearing capacity and working state of the bridge are evaluated by load test.The results show that under the design load,the deflection of the bridge and the check coefficient of the strain of the control section obtained from the static load test meet the requirements of the code,and the bridge is in the elastic range;The vertical frequency of the bridge is also slightly larger than the theoretical value;The bridge is in good working condition.The test provides necessary technical parameters for the safe operation of Moyangjiang Bridge in the future,and also provides important technical data for the appraisal of bridges of the same type.
