Mechanical analysis of segment joint of shield tunnel and research on bilinear joint stiffness model;
盾构衬砌管片接头力学分析及双直线刚度模型研究
2.
The numerical simulation of segment joints of Nanjing metro shield tunnel was carried out with 3D FEM (finite element method).
采用三维有限元法对南京地铁区间盾构隧道管片接头的受力情况进行了数值模拟计算,研究了不同荷载作用下管片接头的变形、转角和抗弯刚度,探讨了接头转角和抗弯刚度的变化规律;通过转角、弯矩和轴力关系的拟合为接头抗弯刚度的确定提供了新的途径。
3.
When simulating the mechanical behavior of segment joints,it is necessary to build a model that is the same with actual joints so as to avoid multiple tolerances.
管片接头是装配式盾构隧道的关键部分,其抗弯刚度对管片环的内力及整体性能均有重要的影响,使得接头抗弯刚度的取值显得尤为重要。
