The relation between the strengthening length of the tunnel anti - seismic and the properties of surround rock of tunnel entrance and the shape of tunnel liner is analyzed 对隧道抗震设防长度与洞口段围岩性质、衬砌断面形式的关系以及隧道洞口段的加固措施进行了研究。
2.
The orderliness of stresses and displacements in the liner along the direction of the tunnel axial are analyzed under various type tunnel liner and multiform properties of surround rock . the effects of shock absorption measure reinforcing surround rock are studied 在不同的围岩材料、不同的衬砌类型情况下，分析了洞口段隧道衬砌应力和位移沿隧道轴线方向的变化规律以及采取注浆加固围岩的方法的减震效果。
