浅埋偏压黄土隧道施工支护优化综合技术研究

Study on the Comprehensive Optimized Supporting Technology in Loess Tunnel Construction

采用三维仿真数值模拟、监控量测等手段对张承高速草帽山黄土隧道浅埋偏压段开挖及支护进行了分析,利用分析结果对施工方案进行了优化。

Numerical simulation of three-dimensional simulation,and monitoring and measuring meth-ods are used in the analysis of the excavation and supporting technology in Caomao Mountain lo-ess tunnel of Zhangjiakou-Chengde Expressway,the results of which are used to optimize the con-struction program.
