抗滑桩开挖爆破振动对民房影响研究

Research on Influence of Excavation and Blasting Vibration of Slide-resistant Piles on Residential Buildings

白鹤滩水电站迁建集镇抗滑桩爆破施工期间,为确保周边民房等建筑物安全,减少因爆破振动导致的纠纷,开展了爆破振动监测和爆破对周边民房的影响研究。通过监测迁建集镇抗滑桩掏槽爆破时诱发的地表振动,探究在新建村方向的爆破振动传播衰减规律;基于回归分析研究了不同爆心距处不同类型房屋的振动响应,提出了爆破振动控制标准。

During the blasting construction of the slide-resistant piles for the relocation of Baihetan Hydropower Station in the market town, in order to ensure the safety of the surrounding residential buildings and reduce disputes over blasting vibration, this paper conducted monitoring of blasting vibration and research on the influence of blasting on surrounding residential buildings. By monitoring the ground vibration induced by the undercut blasting of slide-resistant piles in the relocation township, the propagation attenuation law of blasting vibration in the direction of the newly-built village was explored;based on regression analysis, the vibration responses of different types of buildings at different distances for the blasting center were studied, with control standards of blasting vibration proposed.
