摘要
地铁区间盾构隧道衬砌内力计算是非常复杂的。针对沈阳地铁一号线区间盾构隧道衬砌,分别采用不考虑土壤介质侧向弹性抗力自由变形均质圆环法和考虑土壤介质侧向弹性抗力的修正惯用法进行内力计算。分析比较了衬砌管片结构内力分布规律,探讨了计算方法对盾构隧道衬砌结构设计所造成的影响。
The shield tunnel lining intemal force calculation of metro running is very complicated. A practical engineering example is calculated respectively with free displacement ring method and modified usual calculation method for shield tunnel lining of Shenyang metro line 1. The distribution law of structural internal force of lining segment is compared and analyzed, and influences of different calculation method on structural design of shield tunnel lining are also discussed.
