Soft Soil Foundation

Municipal road and bridge engineering is an important part of the transportation road construction in the city. Its construction quality directly affects the transportation quality and driving safety of the whole municipal road traffic. Among them, the foundation engineering of municipal road and bridge engineering is the main construction link. In the current municipal road and bridge construction process, it is often affected by many factors, leading to the reduction of the construction quality of municipal road and bridge engineering, especially the construction treatment of soft soil foundation in the foundation engineering, which is the main factor directly affecting the construction quality of municipal road and bridge. This paper first introduces the definition and relevant characteristics of soft soil foundation in the construction of municipal road and bridge engineering, and expounds the influence of soft soil foundation on municipal road and bridge engineering, and then analyzes the application of soft soil foundation treatment technology combined with the basic treatment ideas of soft soil foundation in the construction of municipal road and bridge.

Jointless Bridge

Expansion joint of a bridge is a weak part of structure, it leads to early structure destroy and reduces the bridge life. The paper put forward a new type of Jointless Bridge --- Semi–Integral Abutment Jointless Bridge, and its theoretical model was built. An engineering of four spans 100m length Prestressed Concrete Semi–Integral Abutment Jointless Bridge was analyzed, and results that its mechanical performance is so excellent that it should be wide applied in bridge engineering.

Economic Construction

Road and bridge engineering is an indispensable part of socialist economic construction in China, whose construction quality signifcantly affects the infrastructure construction level in the whole society. To meet the rapid economic development of various regions, construction scale and quantity of road and bridge engineering have been continuously expanded and increased, therefore, higher requirements for construction quality and construction standard are also presented. During the construction of road and bridge engineering, concrete crack is a key problem which affects the construction quality. In this regard, this paper analyzes cause and prevention measures of concrete cracks during the construction of road and bridge engineering, and hopes to provide construction personnel with valuable references.
