摘要
盾构隧道管片衬砌的内力及变形受多种因素的影响。用弹性地基梁方法对一具体实例,从土层与衬砌两方面综合分析了影响衬砌内力及变形的各个因素,分析了管片的内力及变形随各参数变化的一些规律,得出了对衬砌内力及变形影响较大的参数。
There are many factors that affect the internal forces and displacement of the shield tunnel segment lining.In this paper,these factors are analyzed from such two aspects as surrounding rock and segment lining by means of the elastic ground-beam model.The rule of the internal force and displacement changing with these factors are summarized and parameters for the factors of significant influence are obtained.
