摘要
针对某高速公路25米箱梁进行了静载试验。主要是通过对试验截面进行逐级加载,观测桥梁结构的应变和挠度。将观测结果和理论值进行对比分析,结合公路钢筋混凝土及预应力混凝土桥涵设计规范,验证结构的安全稳定性能。
A static load test of 30m boxed was made in a certain expressway engineering.In the test,the working performance,deflection and stress,of the precast girderwere both tested at different load effect levels.Then, com?paring and studying the observation results and theoretical values,combined with the design specification of high?way reinforced concrete and prestressed concrete bridges and culverts, judging the safety and stability of the structure.
