| 摘 要： | 为更准确的分析盾构隧道管片的变形特性,对常用的惯用法模型进行修正。并基于修正模型推导管片的位移解析解。结合哈尔滨地铁1#线工程资料,基于修正模型计算管片位移的数值解和解析解,同时计算基于惯用法模型的位移数值解,并将特殊位置处的位移进行对比分析。结果表明,对惯用法模型的修正是合理的,基于修正模型求得的位移解析解是正确的。

| Abstract: | In order to analyze correctly the deformation qualities of shield tunnel segments,a commonly-used model is improved. The solutions to the displacement of segments are analyzed based on an improved model.Harbin Metro Line One is analyzed as a sample to derive analytical solutions and the numerical solutions of the segment displacement based on the improved model. Meanwhile,the numerical solutions of the displacement are calculated based on the commonly-used model and the displacement of some special sections is compared. The result reveals that the improved model is reasonable and the analytical solution of displacement based on the improved model is correct. |
