【摘要】 就如何设计计算高大烟囱或楼房爆破拆除时的塌落振动速度,作者回顾了以往所提出的塌落振动速度计算公式,并对公式及其中参数表述的物理意义与取值作了阐述,以澄清一些引用中对有关参数理解的差异。文中还列举了工程实例,说明公式的应用和公式中各参数的选择。实测数据表明,地面采取减振措施后塌落振动速度可以减小70%。更多还原

【Abstract】 The author,regarding the method of predicting collapsing vibration velocity of high chimney or building during blasting demolition,reviewed the formulas for calculating the collapsing vibration velocity given in references and discussed the formula in terms of its physical significance and its parameter selection for clarifying the discrepancy quoted.The paper explained some applicable formulas and discussed the selection of parameters by taking some practical engineering instances for the calculation of collapsing vibration velocity,and with a statement supported by real time data measurement that the intensity of collapsing vibration velocity could be reduced by about 70% when vibration reduction method was adopted.更多还原
