Analysis and Treatment of Cracks in Cast-In-Place Concrete Slab Beam Structure

Abstract

Cast-in-place concrete slab beam structure is widely used in small - and medium-sized Bridges in our country. In the new period, the traffic volume of road and bridge is increasing, and the phenomenon of vehicle overload is serious. Therefore, cracks will appear in the use of plate and beam Bridges, and some cracks even exceed the maximum value stipulated in the relevant regulations. It will seriously affect the safety and service life of the bridge. It is very important to analyze the cracks of cast-in-place concrete slab and beam structure comprehensively and take effective measures to strengthen them, which plays a very important role in improving the safety of bridge and increasing the service life of bridge. In this paper, the types and causes of cracks in cast-in-place concrete slab and beam structure are analyzed, and effective treatment measures are put forward.
