摘要
赣龙线吊钟岩隧道进口段处于河谷傍山,属浅埋偏压隧道。根据该隧道进口段施工过程中所揭示的新的地质情况和现场量测资料,对该隧道进口段进行了动态设计。同时,在稳定性差的高边坡条件下,对明洞的结构设计进行了探索,所提出的设计思路可供今后类似工程借鉴。
The Diaozhongyan Tunnel inlet setion of Ganlong Railway is located in a valley abutting on a mountain,belonging to a shallow-depth and eccentrical compression tunnel in very difficult geological conditions.According to the status of the surrounding rocks and results of field measuring,the dynamic design has been carried out throughout the construction procedure.structure of the cut-and-cover tunnel has also been probed into under the conditions of poor stability of a high slope.The scheme can be referred to in later similar engineering.
