The Research And Application On Optimization Design Of Highway Soil Side Slope Based On The Economical Risk Analysis

It is the direction of geotechnical engineering development to replace the safety factor with reliability for stability analysis and optimization design of side slope. By using genetic algorithm, the most dangerous glossy search procedures of Highway soil side slope arc undermine and destruction in the reliability calculation process are established and based on this the Highway soil side slope optimization design mathematical model which adopts genetic algorithm optimization solution is also established. The main contents are as follows:â‘ Using the Bishop method to establish Highway soil side slope arc undermine analysis model, developing the most dangerous glossy search procedures of genetic algorithm on the MATLAB terrace.â‘¡Applying reliable theories to build up the ultimate limit state equation and the reliability calculating model, developing the side slope reliability count procedure of genetic algorithm on the MATLAB terrace.â‘¢The dissertation has created the road side slope soil texture design optimized model, and comprehensively considered the cost for the construction and the risk that might be undertake. Then, it executes the utilization mathematics principle and the optimized theory expense and benefit analysis method, takes the lowest construction cost as the number; with the side slope shape and the side slope difference as the design variable, security as the primarily requirement, it establishes the side slope soil texture optimization model. And developing the genetic algorithm procedure of side slope engineering on the MATLAB terrace.â‘£Applying the procedure on some freeway side slope design, it obtains the superior side slope grade and side slope type design project. Based on the MATLAB terrace, the most dangerous glossy search procedures of genetic algorithm, the side slope reliability count procedure of genetic algorithm and the genetic algorithm procedure of side slope engineering are established. Via the case verification, the program is steady, quick, and precise for calculation. It has certain practical value.
