地震救援破拆技术效率研究

以地震救援中常用的开放空间间接安全破拆方法和受限空间水平快速破拆方法为研究对象,探究安全破拆需要两层切割破拆情况下首层破拆深度对整体破拆效率的影响和受限空间水平快速破拆钻孔数量对整体破拆效率的影响。结果表明,安全破拆作业时长与首层切割深度,快速破拆作业时长与钻孔数量均表现为一定的线性正相关关系。对2种方法进行线性回归建模,分别得到了线性回归模型。

Taking the indirect safe demolition method of open space and the horizontal rapid demolition method of restricted space commonly used in earthquake rescue as the research object,this paper probes into the influence of the first layer breaking depth on the overall breaking efficiency and the influence of the number of horizontal rapid breaking holes in the restricted space on the overall breaking efficiency when the safe breaking requires double-layer cutting.The results show that there is a certain linear positive correlation between the safe demolition operation time and the first layer cutting depth,the quick disassembly operation time and the number of boreholes.The two methods are modeled by linear regression,and the linear regression models are obtained respectively.
