Thus, the following detailed description of the embodiments of the present invention, presented in the figures, is not intended to limit the scope of the invention, as claimed, but is merely representative of selected embodiments of the invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
It should be noted that: like reference numbers and letters refer to like items in the following figures, and thus, once an item is defined in one figure, it need not be further defined and explained in subsequent figures. Meanwhile, in the description of the present invention, the terms "first", "second", and the like are used only for distinguishing the description, and are not construed as indicating or implying relative importance.
In fact, the media between the sensor and the blasting point are complex and various, and the material properties are different, such as rock, soil, air, water and the like. When the explosion vibration wave passes through two media with larger properties, complex reflection, refraction and diffraction phenomena are generated, the propagation process is extremely complex, the obtained conclusion is often complex, and the achievement is difficult to convert in the face of practical application. For the safety evaluation of the blasting surface after the blasting surface passes through, the blasting vibration wave can greatly change the properties of media such as air layers and the like, which undoubtedly brings challenges to the safety prediction and damage evaluation of structures under short-distance blasting.
Example 1:
the embodiment provides a building blasting vibration safety evaluation method.
Referring to fig. 1, the method is shown to include step S100, step S200 and step S300.

It should be noted that, in the blasting of an underground tunnel, since complicated reflection, refraction and diffraction phenomena are generated when an explosive vibration wave passes through two media with larger properties, in the present application, the distance between a building and a blasting point is not easy to be too large, and the distance between the building and the blasting point is preferably within 100 m.
Meanwhile, for convenience of explanation, refer to fig. 2, which is a construction diagram. In the application, the small clear distance tunnel is divided into a first-row tunnel and a second-row tunnel, and the distance between two tunnel excavation surfaces is 50 m.

Before blasting, a first sensor group and a second sensor group are respectively arranged in the advance tunnel and the transverse passage for monitoring. In the application, for simplifying and considering the propagation of the explosion seismic wave, through the spatial position relationship, the tunnel face size effect of the backward tunnel cannot be ignored, and the seismic wave of the explosion point is propagated to the backward transverse channel and needs to pass through an air layer with a certain length of x.
