DebrisFlow Control Structure Of Software Developmet And Application

Debris Flow is a typical phenomenon of geological disasters, major debris flow hazards. Debris Flow on the people's lives and property within the region, building structure, and so is extremely destructive. Especially for debris flow ditch or across the ditch along the coast road debris flow will cause devastating damage, often causing long-term road block, and seriously hampering the area's economic development. Debris Flow control difficulties, unexpected strong, and can not easily be monitored and observed. Distribution of a large number of landslides in China, the western region had only road debris flow groove 6000, the Sichuan-Tibet Highway mileage accumulated by the debris flow hazards up to 160 km. National Debris Flow caused by the economic losses amounted to 5 billion yuan each year. In order to control debris flow hazards highway facilities, protection of the normal transport operations, such as Professor CHEN debris flow on the highway had an extensive and in-depth study, based on this and created a row debris flow velocity structure, special-shaped pier, debris flow as the representative of the tunnel Highway debris flow control structure, and avoid or reduce the debris flow on the highway traffic hazards. Through the debris flow control structure of the past experience of the new structure and the detailed calculations and analysis, use of Visual Fortran and Visual Basic development for a major debris flow structure of the structure of software, and works through examples of model tests, numerical simulation Application software method was verified by the main conclusions include:(1) In a mature calculated on the basis of the tunnel structure, in response to such disasters and debris flow control structure of the regional characteristics. Use of "structural mechanics," "Mechanics of Materials" and "fluid dynamics", "tunnel mechanics," "Highway debris flow mechanics" on the basis of the tunnel will be debris flow control structure calculation of the internal forces of programming, which can be better in terms of debris flow Tunnel under the conditions of the outbreak of internal forces of the software, and examples of the application of engineering and numerical simulation of the debris flow tunnel was verified by good results. Software for the development of debris flow and improve the design of the tunnel provided a strong support, raising the debris flow tunnel design efficiency of the work.(2) By CHEN Professor in the "Highway Debris Flow research and governance" in the new speed-control structure to improve the methods of calculation, calculation of elastic foundation principle, cantilever principle and piles of debris flow impact and friction loss calculation principle, The use of computers has been developed debris flow velocity flow structure of the internal forces of software and entities in the model test and engineering applications was verified, the flow speed control for the future structure of the application provide the basis and reference.(3) Have been in geotechnical engineering and hydraulic structure used in the calculation of deepening revetment wall on the basis of the characteristics of debris flow and damage the form of movement, landslides revetment wall structural design and checking procedures for the design, in the light hydraulic and geotechnical aspects of norms, to increase the revetment wall of debris flow checking requirements, and in the wall of the structure to strengthen its.(4) In the debris flow has been stopped slag dam control structure theory and checking engineering calculation method based on the movement of silt and debris flow slurry drainage characteristics, its structure and the structure of a checking process development, and along the Sichuan-Tibet Highway debris flow management projects have been verified.(5) New group piles of debris flow roughness at the end of the structure and the internal force of the pile checking mainly make use of calculated on the basis of principle and Debris Flow movement mechanics. Based on the principle of anti-slide pile group research, Professor CHEN innovation will be introduced to the prevention and treatment of landslides. "Highway Debris Flow research and governance" in the design and calculation methods on the basis of completed at the end of the group piles of debris flow roughness of the internal forces and structural counting procedures, the design of the structure and application provides the basis for calculation.(6) New pier debris flow airfoil design process control structure theoretical basis mainly from the aerodynamics, fluid mechanics and pile foundation design principle. Use of the aerodynamics of the wing surface flow principle, the introduction into the debris flow control structure, in improving the airfoil on the basis of Confucianism's use of conformal mapping method, combining pile design principles have been airfoil pier structure calculation methods and structures checking methods . On this basis, through Visual Fortran and Visual Basic programming joint development of the pier debris flow airfoil structure calculation software.Through the above-mentioned six debris flow control structure calculation of the design process, have been applied to a specific set of debris flow control structures of the system software, for the future structure of the debris flow prevention, and improving the application provides a reliable basis for a variety of mud-rock flow structural design and application of integrated and laid a solid foundation.
