Bearing steel grid corrosion of the components are the main reason, anti-corrosion and water leakage and produce bad flooding, causing severe rust. Cleaning is not timely seismic bearings, inadequate, there dust deposition. Anchor bolts cut, pull out the main reasons are as follows, bearing steel grid is set incorrectly, the range of movement of steel truss bearing prolapse. Less than double the number of Romanian and buying length. Bear no negative bearing reaction force set up fixtures. Mortar filled not dense. Base fill empty mortar, cracks, filling mortar base empty, mainly cracks; no shrinkage mortar filling agent is not dense mix well, good waterproofing and drainage, water immersion internal cracking. Crushed concrete base, peel, crushed concrete and steel truss bearing the main reason for stripping edge distance and lack of seat base Jiaqing steel, steel grid inadequate support and seat cushion stone base size. Mortar filled not dense. Floor junction crack or break under the main reason for the long-term effects of heavy traffic loads, bearing steel grid floor junction fatigue cracking or breaking. Bolt deformation or fracture. In other countries, such as Japan in their respective steel bearing steel truss design manuals are also assessing the extent of damage to the bearing shield MERITS Pan can use for specific tasks. To this end spherical bearing seismic introduce such information. Assessment of Bridge classified into general assessment and evaluation of the use of type. For the full-bridge overall technical condition rating. Consider the use of the various components of a comprehensive re-evaluation of the bridge right method. In the general assessment of the technical condition of the bridge a part of the evaluation method. According to the three aspects battlements defect size, number or severity of the defect structure and the degree of influence the use of functional defects evolving situation, so as to make the cumulative scoring method for grading the parts defect condition. Important components in which the most serious defect components score, other parts seismic steel supports, according to the majority of members defect condition score. The recommended weight of various components visible to the specification, steel grid bearing as important components in which the most serious defect seismic spherical bearing component score in each component of the right to recommend a bridge bearing heavy weights 3, steel grid bearing technical condition assessment standards, specifications for highway bridges and culverts bridge support conservation assessment requirements.
