| Abstract: | Various faults will occur in the course of using the long-span pre-stressed concrete bridge, i.e. forming of various cracks and downwarping in the middle of span, which not only influence the beauty of bridge, but also affects the normal use of bridge. The article sets forth the common faults of the long-span pre-stressed concrete bridge, analyzes their causes, and puts forward some preventive and remedial measures for these faults. |
