【摘要】 以具体爆破挤淤工程为例,实测了水中冲击波力学测线和保护目标处的水中冲击波压力值,分析了爆破挤淤水击波的作用特性和传播衰减规律,给出了水中冲击波的经验计算公式,提出水击波压力安全控制标准。研究结果不仅保证了重点工程的安全施工和周围建筑的安全,而且有助于丰富爆破挤淤理论,指导类似工程实践。更多还原

【Abstract】 Taking the squeezing silt project by blasting as an example,the pressure of shock in wave at measuring line and protected objects in wave is monitored in the operation.The propagation attenuation rule of blasting toe-shooting are analyzed,reaching an empirical calculation formula of shock in wave.As a result,the paper puts forward the safety control criterion of shock pressure in water for protected objects.The result not only ensured the safety of the construction and that of the surrounding buildings,but also complements the theory of squeezing silt by blasting and guides similarity engineering.更多还原
