下穿建筑物隧道控制爆破方案研究

Research on blasting control scheme for tunnels underneath crossing buildings

通过对胶州湾海底隧道工程概况的分析,基于萨道夫斯基公式确定了合理的隧道开挖方案,并提出了具体的减震措施,以满足爆破安全规程要求。

According to the analysis of engineering survey of Jiaozhouwan subsea tunnel, the paper identifies the reasonable tunnel excavation scheme based on Sadaovsk Formula, and points out shock absorption measures, so as to ensure the requirements for the blasting safety.
