摘要
文章介绍丰满三期扩建永庆反调节水库混凝土围堰拆除爆破试验研究内容,包括测试依据、测试仪器、拆除方案、振动和动水压力测点布置、测试成果及分析等;由于坝基地质情况较差,混凝土围堰爆破拆除对坝基和坝体的安全将产生影响,叙述了在围堰拆除时进行爆破的质点振动速度和动水压力监测情况,分析和评价了爆破对坝基和已有建筑物的影响。
The paper introduces the study content of the concrete cofferdam blasting demolition test for Yongqing anti-regulating reservoir of the Fengman three phase extension project,including test foundation,equipment,demolition plan,vibration and hydrodynamic pressure measuring point layout,test result and analysis,and so on.Because of the bad geological condition of the dam foundation,the blasting demolition would affect the safety of dam foundation and body.The paper describes the blasting particle vibration velocity and hydrodynamic pressure monitoring situation during demolition,analyzes and evaluates influence of blasting on the dam foundation and existing structure.
