摘要
针对低应变动力测桩法在测算桩的承载力上存在的问题 ,提出应用BP网络技术来解决动、静对比系数选取过程中存在的随意性问题。在BP算法实现上 ,采用动量法和学习速率自适应调整 2种策略 ,有效地抑制了网络陷入局部极小。该技术应用于测算桩的极限承载力 。
BP networks is used to estimate the load capacity of piles for solving the problem that the dynamic static comparative factor is selected at will. To effectively prevent the BP arithmetic from driving into the local minimum, both the momentum and the self regulation of study speed are used in the project of BP arithmetic, by which the satisfactory result of the load capacity of pile is acquired.
