摘要
采用有限元法对由聚丙烯纤维网湿喷混凝土、锚杆和钢格栅组成的软弱围岩隧道支护结构的应力、变形等进行了分析研究。对危险截面的强度验算表明,使用该支护结构的铁路隧道硐室稳定、安全度高。
Authors use the finite element method to analyze and study stress and deformation of the support structure of a soft adjacent rock tunnel which is built with polypropylene fiber mesh wet_spray concrete, anchor rod and steel grids. The calculation of the strength of dangerous sections testifies that the railway tunnel with this support structure has high stability and safety.
