摘要
基于国际领先的分布式光纤监测系统检测原理,针对结构物局部点的应变变化建立的4层人工神经网络模型,可用于结构物的局部变形预测。该预测方法经隧道实测数据的验证,所得结果令人满意,具有一定的实用价值。
Based on the international advanced measurement principle of monitoring system using distributed fiber optic strain sensor, a model based on neural network with 4 layers is established in allusion to strain change of particular location, which can be used to forecast ＇the structural deformation on particular location. This prediction method has been validated by the test data, and the satisfying results show that it has a certain practical value.
