【摘要】 位移预测对岩土工程稳定性具有重要的实用意义,近来软科学方法得到了广泛重视及应用。对常用软科学方法——灰色系统、时序分析及神经网络进行了系统分析研究,指出了它们的优缺点及适用范围,并提出了一种新型软科学预测方法——进化神经网络法。最后,通过工程实例验证了理论分析的结果。更多还原

【Abstract】 It is very important to study displacement prediction method in geotechnical engineering. Recently, the prediction methods based on soft science have been applied widely. Here, the generally used soft science methods-Grey System, Time Series Analysis and Neural Network are analyzed and studied comprehensively, and their merits and demerits are also revealed. Then, a new prediction method based on soft science-Evolutionary Neural Network is proposed. At last, the results of the theory analysis are verified by an engineering example.更多还原
