复杂环境下水下爆破振动效应控制技术

The Control of the Underwater Blasting Vibration Effect in Complex Environment

混凝土浇筑施工期间,对爆破振动安全要求较高。在莆田LNG码头施工过程中,为了减少爆破振动对周边建筑物以及新浇筑混凝土罐体的影响,采取了减振孔、改变装药结构等减振措施。通过水下爆破实际应用,证明减振孔、改变装药结构等能够有效地减少爆破对新浇筑混凝土罐体的影响。

During the construction of concrete pouring, the requirement is high to vibration safety. In Putian LNG- container pier, shock absorption holes and changing charge structure were used to decrease the effect of the blasting vibration to the surrounding buildings and the new pouring concrete. Through the practical application in the underwater blasting, shock absorption holes and changing charge structure can effectively decrease the influence of blasting.
