摘　　要：本文应用随机介质模型,导出近地表表土及风化层中开挖圆形隧道引起地表移动及变形的有关预计公式。并用BASIC语言编制了适合于IBMPC—XT/AT微型机的电算程序。利用这些结果,可以计算并绘制地表移动及变形的分布曲线。本文计算方法可供城市在软上中开挖地铁及浅部矿山巷道掘进引起的地表移动进行分析。Based on stochastic medium model, The formulas have been derived for predicting ground surface movement and deformation due to near-surface tunnel excavation. A micro-computer program for IBM-PCXT/AT computer has been developed to calculate surface deformation and the associated curves. It is an useful tool for analyzing the effect of tunnel excavation in soil in a city and shallow underground excavation at mines.
