| 摘 要： | 陆浑水库溢洪道闸墩基础1m以上需爆破拆除,周围环境复杂,距右墩21m处有一栋三层危房。为防止爆破产生的震动效应导致危房现状的恶化,工程初期进行了现场爆破试验。试验研究了爆破震动的传播衰减规律和楼房的振动动力响应,确定了爆破安全控制标准。试验结果有效地指导了爆破设计和施工。

| Abstract: | The foundation above lm of spillway pier of Luhun reservoir was projected to be demolished through blasting. On account of complicated surroundings and a three-floor dilapidated house about 21m far from the right pier, blasting experiment was carried out so as to avoid blasting vibration to worsen the dilapidated house. In the early phase of the project transmission of blasting seismic wave and dynamical effect of storied building was studied,and blasting safety control standards were determined. The result effectively instructed the blasting design and construction. |
