Security Identification Technologies for Stone Arch Bridges at Service

The typical diseases of stone arch bridge in the Three Gorges Reservoir area are summarized through the investigation, and four kinds of typical diseases of stone arch bridges are investigated and evaluated by spatial finite element software. Based on these investigations, the limited value index of the security and the identification technology of the four typical diseases of the bridge are ob...

Multidisciplinar Aproach to Historical Arch Bridges Documentation

This paper describes the project of the Close Range Photogrammetry and Remote Sensing Group, University of Vigo, Spain, involving historic arch bridges in Galicia, Spain. The first aim of this Project consists on building a database of the historic arch bridges in Galicia, documenting location, surroundings, geometry, singular characteristics, structural faults, building material and state of c...

Failure Modes Analysis of Stone Arch Bridges

A destruction test based on the bridge safety appraisal is one way to verify the failure law of an actual bridge. In this paper, a stone arch bridge in a 1:10 scale model and with a span of 60 m (namely, an arch bar of the same length as the object of test) has been tested, methods of its whole test and loading process introduced, and ultimate bearing capacity, deflection and development rules ...

Hydraulics of River Flow Under Arch Bridges

IN T R O D U C T IO N Bridges are an integral part of any highway system. The design of a particular bridge depends on many variables. A major considera­ tion, often necessary, is the length of the bridge. In certain circum­ stances and locations the length may be dictated by factors other than cost. But, where necessary the designer must decide, “How far can the bridge approaches extend onto t...
