引水隧洞爆破开挖对邻近建筑物的振动影响分析

Effect of Diversion Tunnel Blasting Excavation on the Vibration of Adjacent Construction

以发电引水隧洞开挖过程中的爆破振动实测数据为基础,对爆破振动衰减规律进行了二元回归分析,与萨道夫斯基公式相比,预测数据更接近实际工程。同时对隧洞爆破开挖过程中邻近建筑物的安全,根据实际监测成果作了进一步分析,给出了相应的爆破安全判据。

Based on practically measured data of blasting, vibration in the process of hydropower diversion tunnel blast excavation, the duality regression analysis of attenuation equation of blast vibration is made. Compared with experimental formula, the forecast data was made close to the engineering reality. Simultaneously, the safety of adjacent constructions in the process of tunnel blast excavation based on the monitoring result is analyzed to provide corresponding safety criterion.
