摘要
用Laplace函数导出了城市地下隧道开挖引起地表移动变形分析的数学模型,并用该模型对具体的工程实例进行了计算分析.用Matlab语言绘制了地下开挖引起地表移动变形曲线图.把理论分析结果和现场实测资料相比较,二者吻合,证明导出的数学模型可用于预测分析城市隧道开挖地表移动,计算结果对城市隧道施工具有一定的指导意义.
The mathematical models of ground surface movement and deformation caused by underground tunnel excavation in the city proper were established by using Laplace function and the engineering examples were analyzed by using the models. Then, the analytical program was developed by Matlab and the profile figures of the ground movement and deformation were drawn. The agreement of the theoretical results with the field measurements shows that the models are satisfactory. So the models can be applied to predict ground surface movement due to underground tunnel excavation in the city proper. The conclusion obtained has some significance in guiding the tunnel construction.
