Study on design method of shield tunnel segment
-
摘要: 本文回顾了隧道结构理论与方法研究,综述了目前国内外常用的方法,即惯用法、修正惯用法、多铰环法和梁-弹簧模型法,介绍了壳-弹簧模型,最后提出了岩土介质-盾构隧道有限元体系.Abstract: This paper reviews the research of theory and method of tunnel,summarizes four major segment designs,that is,routine method,modified routine method,multi-hinge ring method and beam-spring model method,and introduces shell-spring design model.A new idea of rock soil medium shield tunnel design model is put forward.
