摘要(Abstract):

介绍了采用控制爆破技术拆除三座大型碉堡的实例。碉堡位于机场区内 ,结构较为特殊 ,环境较为复杂 ,爆破拆除安全要求较高。拟制了揭顶盖、爆墙体 ,炸基础、处理地坪的施工顺序 ,符合实际。爆破 80余次 ,消耗电雷管千余发、炸药百余千克 ,安全、快速、低耗 ,为类似工程提供了宝贵经验。
This paper introduces an example about demolishing three large blockhouses by controlled blasting. These blockhouses, located in an airfield, have particular structure and complicated surroundings. According to the actual conditions, the construction sequence is decided: to uncover the copings, burst the walls, blast the foundations and level the ground. This case of blasting is finished with safety, celerity, low costs and provides valuable experience for similar projects.
