| 摘 要： | 以广州某浅埋暗挖隧道工程为依托,采用有限元法对短台阶施工法中格栅钢架选型及其布置方案进行研究。首先根据工程实际提出三种格栅钢架布置方案,再对不同格栅钢架布置方案下的地表沉降、格栅钢架应力、衬砌应力等有限元计算结果进行分析比较,确定适合该工程的格栅钢架支护方案,其研究思路与方法可为同类工程提供参考。

| Abstract: | Relying on a shallow tunnels project in Guangzhou,employ finite element method to research the selection and layout scheme of grille steel frame in short-step construction method.First propose three layout schemes of grille steel frame according to the engineering practice,and then analysis and compare the results of the surface subsidence,the stresses of grille steel frame and lining under different layout schemes.At last,the most suitable support scheme of the project is obtained,while the thinking and the method provide a reference for similar projects. |
