Abstract

The invention discloses a railway bridge geological graph digital storage and application method, which comprises the following steps of: the geological condition of the whole railway project line is counted, and a stratum index library of the whole line is established by taking the stratum name, the stratum state and the basic bearing capacity as indexes; geological data provided by the geological specialty are sorted, and a full-bridge geological information base is established with a single bridge as a unit; basic characteristics of the geological drilling map are analyzed, drilling information is stored in a drilling table, drilling stratum information is stored in a stratum attribute table, and drilling filling lines are stored in a drilling filling table; basic characteristics of the geologic profile diagram are analyzed, and drill hole connecting lines are stored in a stratum connecting line table; an earthquake liquefaction judgment calculation sheet is designed and stored in an earthquake liquefaction table, and a digital soil sample consolidation test report graph is stored in a compression modulus table; and bridge calculation is performed according to the pier mileage position in the bridge table, the stratum index library and the full-bridge geological information library. The method guarantees the calculation accuracy, accelerates the design progress, improves the labor efficiency of workers, and reduces the labor intensity.

Description

technical field [0001] The invention belongs to the technical field of railway bridge engineering in the transportation industry, and in particular relates to a method for digitized storage and application of geological graphics of railway bridges. Background technique [0002] With the continuous improvement of railway design speed, the proportion of bridges is increasing, and the length of high-speed railway bridges often accounts for more than 80% of the entire line. In recent years, railway design tasks have shown the characteristics of short, frequent, and fast, but the geological data in the bridge general design software still needs to be manually input. The amount of geological data is large, and the input process accounts for more than half of the entire design process. It needs to be guaranteed by reviewing over and over again. Therefore, design efficiency and design accuracy still need to be improved. [0003] Geological data are provided by geology majors, mostl...
