摘要
拱盖法是基于浅埋暗挖理论基础之上、结合"上软下硬"地层特征延伸而出的一种新工法,它解决了传统分部开挖法受力转换多、废弃工程量大、爆破震动影响大、作业空间狭小等问题,具有良好的经济效益与社会效益。
Arch cover method is a new method based on a shal ow-buried excavation theory, combined with the features of softness over hardness formation, which solves the problem that the traditional partial excavation method has more force tr-ansformation, large quantities of waste, big blasting vibration effect, narrow working space and other issues, has a good eco-nomic benefit and social benefit.
