摘要:
隧道开挖爆破作业复杂多样,需根据不同的作业条件和围岩类型采用不同的爆破方法。在舟山西堠隧道开挖过程中遇到非常多变的地质坏境条件,诸如地下溶洞、断层、围岩类型变化大等问题。针对这些特点我们运用了不同的爆破开挖方法,特别是在Ⅱ、Ⅲ、Ⅳ、Ⅴ类不同地质围岩段,有针对性地采取了差别化的爆破开挖方法,取到了较好的爆破效果和经济效益。本文对西堠隧道爆破开挖施工经验进行了总结,可供同类工程借鉴及参考。
Abstract:?
The tunnel excavation blasting is complex and diverse,different blasting technologies are adopted based on dif-ferent working environments and types of surrounding rock.In the process of Zhoushan Xihou Tunnel excavation,very varia-ble bad geological environment conditions such as underground cave,faults,and great changes of surrounding rock types are encountered.According to the characteristic,we use different blasting excavation methods for different geological rock sections,especially in the Ⅱ,Ⅲ,Ⅳ and Ⅴ sections,and finally good blasting effects and economic benefits are achieved.The paper summarizes the construction experience of Xihou Tunnel blasting excavation,which can provide a ref-erence for similar projects.
