Mechanical Analysis and Safety Measures of Expressway Overpass Demolition
The Jinyang Expressway reconstruction and expansion engineering is Shanxi's first"four-lane to eight-lane"project with complex and various geological conditions along the route.For the original road section,the technical standard was low and traffic volume was high,so,under the condition of half-constructing half-opening to traffic,the safety production pressure in the construction period increased significantly.This paper used MIDAS Civil to conduct the physical modeling and stress analysis of the demolition process of the reinforced concrete continuous box girder bridge.According to the calculation result,the demolition scheme was reviewed and the safety control measures were improved.This paper can guide the safe and fast demolition construction of similar bridge engineering.
