- Abstract
In the design of highway, the simplified bishop algorithm is used to analyze the body stability of the embankment itself and the overall stability both embankment and foundation according to the requirements of specification generally. It is used to determine the most dangerous slope sliding surface and the corresponding minimum factor of safety. The enumeration algorithm frequently adopted in engineering practice requires a given hunting zone and its computation speed is slow. Traditional optimization algorithm such as step-acceleration method results in local extremum and other shortcoming easily. Based on particle swarm optimization (PSO), a method combining simplex method and particle swarm optimization (SM-PSO) is put forward. And it is proved that it has obvious improvement in convergence speed and adaptability when comparing with PSO algorithm in optimization efficiency and optimization performance.
