Design of 20m prestressed concrete simply supported box girder bridge

The "Hexi Project" is located in the northeast of Sichuan Basin, and the wind speed is low in the transition zone from the hilly area in central Sichuan to the low mountainous area in northern Sichuan. The climate natural ecological zone protection area, Gouxi River, is rainy from May to June (similar to the Meiyu in the south of the Yangtze River). From July to August, it is controlled by the subtropical high pressure, hot and dry, with low annual precipitation and no record of catastrophic floods.

Graduation Thesis of Prestressed Concrete Simply Supported Hollow Slab Bridge
The development of transportation and the realization of modern transportation extending in all directions play a very important role in the development of the national economy and the consolidation of national defense. In the construction of roads, railways, urban and rural road traffic and water conservancy, various types of bridges and culverts must be built in order to cross various obstacles (such as rivers, valleys or other lines). Therefore, bridges and culverts have become an important part of land transportation. Economically, the cost of bridges and culverts generally accounts for 10% - 20% of the total cost of highways. Especially in the construction of modern high-grade highways and urban viaducts, bridges are not only very large in project scale, but also often the key to ensure the early opening of the whole line.

Construction organization design of prestressed concrete simply supported hollow slab bridge
1. The XX medium bridge is located on the straight section, and the piers and abutments of the bridge are arranged in parallel. The bridge starts at K0+071.980 and ends at K0+128.020, with a total length of 56.04m. The upper structure is 4 × 13m pretensioned prestressed concrete simply supported hollow slab, and the whole bridge has a total of one link, with continuous deck; The substructure is column pier and abutment, and bored pile foundation. Deck width: 0.5m crash barrier+7.0m carriageway+0.5m crash barrier. D60 expansion joint device is set for the whole bridge. 2. Load standard and seismic intensity load standard: highway - Grade I 3. Main materials (1) Concrete grade: C50 concrete for upper hollow slab, bridge deck pavement and cushion stone; C40 concrete is used for the end head of hollow slab; C30 concrete is used for pier column, pier cap beam, abutment cap beam, retaining block, anti-collision guardrail, back wall and approach slab; C25 concrete is used for pile foundation. (2) Steel: A. Prestressed steel strand: low relaxation high-strength steel strand with nominal diameter of 15.20mm and nominal area of 140mm2 is used. B. Ordinary rebar: HRB335 hot-rolled deformed rebar and R235 (A3) plain round rebar are used. C. Steel plate: Q235B steel plate. (3) Bearings: GYZ rubber bearings are used at all piers of the whole bridge, and GYZF4 tetrafluoro sliding plate bearings are used at the abutment. (4) Expansion joint: 2 D60 expansion joint devices are set for the whole bridge. 4. Natural conditions (1) The geographical location, topography and geomorphology of the project are mainly low mountains, hills and intermountain plains, which generally represent the geomorphic framework of high in the west and low in the east, separated by mountains and basins. The altitude of the plain is mostly between 4 and 20 meters; The low mountains and hills formed by the Cenozoic volcanic rock landform and Aishan Mountain range are mostly between 50 and 200 meters above sea level. (2) Seismic peak ground acceleration system: 0.05g. The basic seismic intensity is VI. (3) The surface water system in the area where the rivers and hydrology projects are located is developed, and the groundwater is generally Quaternary pore phreatic water. The supply source is mainly atmospheric precipitation vertical and groundwater runoff from outside the area. Because the terrain of this area is not undulating, the groundwater is related to fissure extension movement along with the terrain. A small part of the groundwater in the mountain area flows underground in the coastal plain, and most of it is in the form of subsurface flow, Gather in the valley and converge in the river. (4) Climate This area belongs to the humid monsoon marine climate of the north temperate zone, with four distinct seasons and mild climate. There is no severe cold in winter and no intense heat in summer. The annual average temperature is 11.8 degrees, the frost free period is about 200 days, and the annual precipitation is about 600mm, mostly concentrated in July, August, and September.
