APPLICATION RESEARCH ON BEARING CAPACITY CHECKING CALCULATION OF OLD BRIDGE IN-SITU WIDENING RECONSTRUCTION
Summary,in recent years,the construction of highway network in our country has been developing and improving,the regional connection is becoming more and more close to some extent,and the traffic volume is also increasing significantly.Therefore,the old bridge in-situ widening and reconstruction projects continue to emerge.To some extent,the problem of traffic congestion has been alleviated.This paper is aimed at the old bridge in-situ widening and transformation project.The load bearing capacity of the test beam is checked and calculated on the real bridge.The old bridge side beam of the original bridge is used as the external beam after the bridge reconstruction.To judge whether the actual bearing capacity can meet the requirements of current design and traffic load.
