摘要
本文基于不连续介质变形体的界面应力元理论和方法，建立了盾构式输水隧洞的计算模型．该模型放松了离散单元交界面上的位移连续条件，可以较好地模拟盾构隧洞外衬管片之间螺栓的连接作用和各种缝面的不连续变形特征．理论分析和工程算例表明，本文提出的分析模型仿真性强。
Based on the theory of interface stress element for discontinuous media,a computational model of shield tunnel for water conveyance is estabilished in this paper.In the model,the continuous condition of interface displacement is neglected and the effects of binder bolt for connecting the sectors of liner tubes as well as the discontinuous deformation characteristics of various cracks are simulated.Theoretical analysis and practical computation results show that the proposed model is accurate and efficient.
