| Abstract: | Taking the five-continuous span hollow steel concrete arch bridge with 72.87 m major arch span value in Lin-Tong as an example,the paper establishes finite element analysis model,studies the stress distribution condition,determines the stress testing scheme of main arch circle,and carries out timely monitoring for the stress testing point in construction process,and correctly grasps the stress condition of the main arch circle.As a result,it ensures the smooth bridge construction and standard engineering quality. |
