| 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. |
