Optimal Design of Double Sheet Piles in Deep Foundation Pit Based on UD-SVM

Article Preview

Abstract:

In allusion to double sheet piles(DSP) global optimal solution, the response surface(RS) technique based on Uniform Design- Support Vector Machine(UD-SVM) was introduced to build the RS by nonparametric regression, thus to avoid the complex non-linear RS form between the double sheet piles parameters and indexes under the current standard. Use the Monte Carlo simulation as generator to produce samples, the RS can do considerable and non-repetitive efficiency prediction and get global optimal value satisfying to the target value with high accuracy and stability, also without figuring out the explicit formulations. This article applied the method to a double sheet piles optimal design, and took minimum engineering quantity as criterion to screen for the optimal parameters aiming at illustrating the feasibility.
