摘要
羊栈岭隧道围岩软弱破碎,采用钢支撑进行补强加固。根据隧道的断面建立了相应的计算模型,采用荷载结构法对衬砌内的应力进行计算,并基于该计算结果对加固后隧道的稳定性进行了校核。
Steel supports are used to remedy and reinforce the soft broken wall rocks in Yangzhanling tunnel. The relevant calculated models are established based on tunnel sections, Load structure method is used to calculate the internal stress in linings; moreover on the basis of this calculated result, a calibration is made on the stability of the reinforced tunnel.
