摘要
MHB碎石化施工产生的波动冲击力对周围建筑物有一定的破坏作用。基于波动理论,提出了一种预估振动影响范围的实用计算方法,并结合实际工程,利用Opensees有限元软件进行了分析和验证,为MHB碎石化技术的安全施工提供了理论依据。
The blast wave impelled by MHB rubblization construction has the destructive effort to the near buildings. A practical calculation method is advanced to forecast the range of the destruction. Besides, the analysis and validation to the actual project are carried through using Opensees software. The method provides theory foundation to guide safety construction of MHB rubblization technique.
