Exploration on the Influence of Underwater Blasting Vibration on Building Structure and Vibration Reduction Technology in Waterway Regulation Project

水下爆破是航道整治工程中常用的施工方法,但其产生的振动会对附近建筑结构造成不同程度的影响。本文通过对水下爆破振动的传播机理、影响因素进行分析,结合工程实例,研究了水下爆破振动对建筑结构的影响。通过对比不同爆破参数下的振动监测数据,得出了影响建筑结构的关键因素,并提出了相应的减振措施。本研究对于指导类似工程施工具有重要意义。

Underwater blasting is a common construction method in waterway regulation engineering,but the vibration generated by it will cause different degrees of influence on the nearby building structure.This paper analyzes the propagation mechanism and influencing factors of underwater blasting vibration,and studies the influence of underwater blasting vibration on the building structure combined with engineering examples.By comparing the vibration monitoring data under different blasting parameters,the key factors affecting the building structure are obtained,and the corresponding vibration reduction measures are proposed.This study is of great significance for guiding the construction of similar projects.
