摘要
拟建的丰泽街隧道在泉厦高速公路大坪山隧道下穿过,其平面交角为50°,两洞间岩层厚度仅为6.44m。为了判断两洞交叉处围岩的稳定性,对其进行了三维有限元计算,分析了围岩的应力与变形状态,建议了相应的开挖、支护方法和施工时的监测内容。
The Fengzeijie Tunnel to be planed will pass through under the Dapingshan Tunnel located in the Quanzhou-Xiamen Expressway with a crossing angle of 50°in the horizontal plane.At the grade separation section the thickness of rockmass between the two tunnels is only6.44m.In order to judge the stability of the surrounding rockmass at the intersection,the stress and the deformation states in the rockmass were analyzed by a3D finite element computation,and the related excavation and supporting methods as well as the monitoring items during the period of construction were suggested.
