| 摘 要： | 龙眼睛隧道位于国道213线紫坪铺库区改线公路K1 028 336.5 m～K1 029 270 m处,隧道在开挖过程中围岩多处发生塌方,并且围岩的最大变形量达到了100 cm,发生了严重的大变形破坏.本论文利用FLAC3D软件对隧道开挖进行了三维数值分析,从应力、位移和破坏区3个方面分析了围岩破坏的原因,并在此基础上提出了围岩支护措施.

| Abstract: | The Longyanjing tunnel is located at K1028+336.5~K1029+270 of G213.The wall rock collapsed in many place and the serious great distortion of the wall rock took place as the most displacement of wall rock had achieved 100cm.The authors simulated characteristic of wall rock using FLAC3D.The reason of failure was analyzed for the stresses,displacements and plastic zones.This article presented the shoring methods based on numerical simulation. |
