Study on Engineering Materials with Optimization Design of Pile-Anchor Support for Foundation Pit Based on Uniform Test and SVM Response Surface

摘要

Engineering materials has been achieved significant development in recent years. Combined with the advantage and disadvantage of several common methods, a new optimization method of pile-anchor support for foundation pit based on uniform test and SVM response surface is been proposed. The uniform test can be used to construct study samples efficiently. The SVM is taken advantage to build a more accurate response surface relationship and predict results of large number of random samples. Then, according to constraint conditions of optimization criterions, the best optimization result screened out from results. Through an engineering optimization example, it is showed that this method is not only efficient, but also significantly reduces the engineering quantity and saves engineering materials compared with original design.
