摘　　要：本文以众多的现场观测资料分析和成功的实践经验为基础，建立了厚冲积层条件下非采动地表沉陷引起不同结构井筒井壁的应力状态的系列理论计算公式和参数的确定方法，为预防和治理非采动地表沉陷对井筒的不利影响。Based on numerous field observation data and experience,a series of theoretical formulas and the method for defining the parameters involved are proposed,for determining the stress states of walls of shfts with different structures induced by subsidence of thick alluvial deposits、 This may serve as a scientific basis for prevention and control of the adverse effect on shafts produced by subsidence of thick alluvial deposit.
