CALCULATION OF LOAD CARRYING CAPACITY AND STATIC LOADING TESTS OF DOUBLE-CURVED ARCH BRIDGE
The double-curved arch bridge is widely constructed in the 1960s and 1970s featuring low cost,large load capacity,and convenient construction. Due to the low design standard,poor construction quality,and overload-ing of loads,different degrees of diseases have appeared,affecting the safe operation of the bridge. Taking the testing project of Chenguang Bridge as the case,the process of bearing capacity calculation and static load test is detailed. The measured data of static load test in comparison with the theoretical data is comprehensively analyzed. The re-sults show the safety reserve of the bridge no longer meets the safe operation. Reinforcement recommendations for the same type of bridge quality assessment are proposed for the disasters that do not meet the requirements of the bearing capacity of the parts.
