摘要

根据某开发区台地平整爆破作业造成周边村落民房损伤的实地踏勘结果,对闽南农村各种结构类型,特别是石结构房屋在爆破地震影响下的损伤特征进行了详细描述,并分析了造成震害的主要原因。在对民房损伤等级分布统计分析基础上,得到了闽南地区石结构房屋抗震能力差是造成爆破震害的主要因素和闽南地区石结构房屋的爆破安全振速尚待进一步研究等结论。最后,提出了减轻爆破地震对闽南石结构房屋影响的措施和开展闽南地区石结构抗震加固研究,以增强闽南农村房屋防灾能力的建议。
The damage characteristics of rural house,especially stone masonry house in Southern Fujian province under blasting vibration were described in detail based on the field investigation on the damage of the rural houses due to the site blasting operations.Based on the field investigation results,a statistics analysis of the damage degree to different blasting distance and different structural type of rural houses was conducted.It is indicated that the vulnerability of stone masonry house to blasting vibration is the main reason of severe damage,and the safety vibration velocity for stone masonry house in southern Fujian province is still awaited to be studied.Finally,some recommendations for reducing the blasting vibration damage to rural houses and an urgent need to study the seismic retrofit method for stone masonry house are proposed.
