Based on MATLAB system, a multi-layer back propagation neural network model was developed, in which the effects of the depth from surface to the tunnel axis, tunnel diameter, groundwater level, as well as the elastic modulus, shear strength, side pressure

采用MATLAB系统开发了一个多层反向传播神经网络模型，考虑了隧道的深度、隧道的直径、地下水位、土的弹性模量、土的剪切强度、土的侧压系数、土的重度和开挖间隙对地表沉降的影响。
