The Design Of Long Quan Hydraulic Complex
(Downstream Dam Site, Design Program Of Concrete Gravity Dam)
ABSTRACT
Under the basic information of Long quan water control project such as hydrology and meteorology, engineering geology, natural building materials and transportation conditions, and other basic information, the graduation project design some hydraulic structures that can both meet the condition for water project construction and meet the task it undertake. This graduation project mainly contains the design of concrete gravity dam.
The design elements of this design include the following aspects:①According to the basic information selecting the appropriate dam site, project layout, to determine the level of engineering and major buildings and to determine the elevation of excavation ;②non-overflow dam design，including the determination of crest elevation，the practical dam section，the computing of ultimate limit state, serviceability limit state calculations and stress calculation;③the design of overflow dam, including the determination of weir crest elevation by comparison, to determine the profile dimensions, ultimate limit state and serviceability limit state calculations of dam foundation face and stress calculation;④The design of detailed structure, including crest construction, dam parting and sealing, to constrain seepage and drainage in dam, dam corridor and the district of concrete;⑤Foundation treatment, including foundation excavation, consolidation grouting, curtain grouting and drainage;⑥The design of service bridge, including the force calculation, reinforcement computation, the calculation of crack checking and the calculation of rings and so on .
Keywords: basic information; profile design; limit state; stress calculation; reinforcement calculation
