摘要
以复杂环境下一座150m钢筋混凝土烟囱爆破拆除为例,分析了高耸建筑物塌落触地振动产生的危害。介绍了爆破切口位置和爆破参数的选取、安全防护措施、减小振动和产生次生危害的措施,对比分析了爆破振动监测结果与最终爆破效果,保证了周边建筑物和各种管线的安全,达到了预期的效果,可为类似工程提供参考。
Taking a 150m high reinforced concrete chimney blasting demolition project in complex envi- ronment for instance, hazards of towering building collapsing touchdown vibration were analyzed. The selection of blasting cut and blasting parameters, and measures of safety protection, reducing vibration and secondary hazards were introduced also. On this basis, blasting vibration monitoring results and blasting effects were compared. Analysis showed that those measures ensured the safety of the surrounding buildings and various pipelines and achieved the expected results. It could provide a reference for similar projects.
