浅埋暗挖法新趋势

New Trends of Shallow-cover Mining Method

为了探索与研究新形势下浅埋暗挖法的发展出路,通过对近10年国内采用浅埋暗挖法的12项典型工程设计思路、施工效果的论述分析,结合21世纪经济社会新形势,提出浅埋暗挖法的发展新趋势。主要趋势有:1)强化辅助工法,简化主要工法;2)提高机械化、自动化、数字化水平,减少劳动力投入;3)控制好辅助工法阶段施工风险至关重要;4)辅助工法的造价将成为决定浅埋暗挖工法竞争力的重要因素。

The design concepts and construction results of 12 shallow-buried tunnels constructed by mining method in China in the past decade are discussed and analyzed. New trends of shallow-cover mining method are summarized, which includes： 1 ） strengthening the assistant construction methods and simplifying the main construction method; 2 ） improving the mechanization level, the automation level and the digitization level so as to minimize the labor require- ment; 3） bringing the risks of the assistant construction methods under effective control; 4） minimizing the cost of the assistant construction methods.
