浅埋偏压隧道盖挖法施工全过程数值模拟

摘要

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.%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。
