摘要
对盖挖法施工的全过程进行了弹塑性数值模拟,研究表明,盖挖法可保证山体稳定,同时避免洞口段大开挖,保护环境。
Elastic - plastic numerical simulation is performed in the overall process of covered excavation method construction. The research shows that covered excavation method can guarantee stable mountain and mean- while avoid heavy excavation in the entrance of the cave to protect the environment.
