摘要

根据景德镇-黄山高速公路某隧道现场工程地质条件和隧道结构设计参数，采用有限差分法对喷射500 mm普通混凝土支护和喷射200 mm厚聚丙烯纤维混凝土支护两种支护结构，进行了施工过程的数值模拟分析。从围岩的应力、位移和塑性区分布3个方面对隧道围岩的稳定性进行了分析。模拟计算结果表明，采用喷射200 mm厚聚丙烯纤维混凝土支护结构的隧道围岩能够处于稳定状态。

Abstract

In combination with the real geological engineering conditions and the design parameters of the tunnel layout

numerical analysis is performed to analyze the rock mass stability for two different supporting structures

the ordinary concrete lining with thickness of 500 mm and the wet-sprayed polypropylene fiber reinforced concrete lining with the thickness of 200 mm respectively. The tunnel rock mass stability is analyzed for the stress

displacement and plastic zone distribution. The numerical simulation shows that the lining structure using the polypropylene fiber reinforced concrete is stable.
