Detailed Description
For the purpose of making the objects, technical solutions and advantages of the embodiments of the present invention more apparent, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention, and it is apparent that the described embodiments are some embodiments of the present invention, but not all embodiments of the present invention. The components of the embodiments of the present invention generally described and illustrated in the figures herein may be arranged and designed in a wide variety of different configurations. Thus, the following detailed description of the embodiments of the invention, as 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 made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
It should be noted that: like reference numerals and letters denote like items in the following figures, and thus once an item is defined in one figure, no further definition or explanation thereof is necessary in the following figures. Meanwhile, in the description of the present invention, the terms "first", "second", and the like are used only to distinguish the description, and are not to be construed as indicating or implying relative importance.
In practice, the medium between the sensor and the explosion point is 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, and the obtained conclusion is often complex, so that the achievement faces the practical application and conversion difficulty. For the safety evaluation of the blasting surface after passing through the rear, the blasting vibration wave can pass through the air layer and other medium properties to change greatly, which clearly brings challenges to the safety prediction and damage evaluation of the structures under close-range blasting.
Example 1:
in this embodiment, a method for evaluating safety of blasting vibration of a building is provided.
Referring to fig. 1, the method is shown to include step S100, step S200, and step S300.

In the present application, the distance between the building and the explosion point is not easily excessively large, and is preferably within 100m, because complex reflection, refraction and diffraction phenomena are generated when the explosion vibration wave passes through two mediums with large properties in the explosion of the underground tunnel.
Meanwhile, for convenience of explanation, refer to fig. 2 for construction schematic. In the implementation process of the method, small-clear-distance tunnels are divided into a preceding tunnel and a following tunnel, and the distance between the excavation surfaces of the two tunnels is 50m. A transverse channel is arranged behind the excavation surface of the backward tunnel to connect the two tunnels. And performing blasting excavation on the backward tunnel, wherein the middle cutting blasting of the tunnel face is taken as a blasting point. Before blasting, a first sensor group and a second sensor group are respectively arranged on the forward tunnel and the transverse channel for monitoring. In the application, in order to simplify and consider the propagation of the explosion seismic wave, through the spatial position relation, the size effect of the tunnel face of the backward tunnel cannot be ignored, and the seismic wave of the explosion point needs to pass through an air layer with a certain length x when propagating to the backward transverse channel.

It should be noted that if there is more medium between the building and the blast point, then only λ in the formula 1 x+λ 2 y+z is increased by more parameters. If there are only two mediums between the building and the blast point, λ 1 x+λ 2 y+z is rewritten as lambda 1 x+y.
In the step, the blasting vibration of the medium layers with different attributes is considered by actually arranging a plurality of mediums between the building and the blasting point, so that the safety of the building is evaluated more accurately, the productivity and the production efficiency are liberated as much as possible, and the cost is reduced.
