随机优化

• At last , the comparative calculation and the random optimum analysis about differences between dissimilar distributions of pile rigidity , different variance coefficients and variance relativity were done with the datum from engineering instances . some significant conclusions are also made from the discussing of the factors influencing pile capping beam the internal force
  最后结合工程实例，进行了比较计算，并对不同基桩刚度分布、不同变异系数、以及不同相关性进行了随机优化分析，对影响桩基承台梁内力的各种影响因素及其规律进行了探讨，得出了一些重要结论。
