The Key Construction Techniques of Long Span Continuous Rigid Frame Bridge of the Expressway in Mountain Areas

Abstract:

At present, long span continuous rigid frame bridge is widely used in the expressway in mountain areas. Mountain areas have the features of terrain with continuous ridges and peaks, crisscross network of ravines, changeable climate and large temperature difference between day and night, while continuous rigid frame bridge of the expressway in mountain areas usually has long pile foundation, great bulk of bearing platform, high main pier and long span, which all increase the construction difficulty of long span continuous rigid frame bridge of the expressway in mountain areas. This paper will take the construction process of Longtan River Bridge built in Hurong Xi highway in Hubei province as an example, to study and discuss the key construction techniques of long span continuous rigid frame bridge of the expressway in mountain areas.
