摘要
针对强夯加固效果评价方法的不完善性和影响因素的非线性,应用改进的BP网络算法,建立了BP网络预估模型,对软土地基的强夯加固效果进行预估,并以收集到的工程实例数据加以检验.结果表明,模型的输出和实际值之间的误差为±4 8%,能够满足工程需要.
For the faultiness of evaluation of dynamic consolidation result and the nonlinear of the influence factor,the BP network estimate model is established which can be applied to improve BP network,to estimate the improvement result on soft soil,and to examine the collected engineering data .It is indicated that the error between the output of the model with actual one is±4.8%,which can satisfy the engineering demand.
