Problems solved by technology

[0004] The dynamic protection method based on the structural shape will affect the use and function of the structure because of the optimization of the structural shape, and the construction is also relatively complicated
For the dynamic protection method based on lightweight porous materials, lightweight porous materials are prone to damage under dynamic loads such as shock waves, and the destruction and collapse of a large number of holes in the material will lead to large deformation of the buffer layer material, which loses its load-bearing effect and then Cause large deformation of rock and soil, thus affecting the overall stability of underground structure and surrounding rock

Abstract

The invention discloses an energy dissipation vibrator and a standing wave area power protecting system and method and belongs to the technical field of underground engineering. The energy dissipation vibrator comprises an upper shell, a lower shell, a telescoping rod, a mass block, a first spring and a second spring. A first blocking part is arranged at the lower end of the upper shell. A second blocking part is arranged at the upper end of the lower shell and located between the first blocking part and the shell. The first blocking part limits the second blocking part. One end of the telescoping rod is connected with the upper shell, and the other end of the telescoping rod is connected with the lower shell. The telescoping rod is sleeved with the mass block, the first spring and the second spring. One end of the first spring is connected with the upper shell, and the other end of the first spring is connected with the mass block. One end of the second spring is connected with the lower shell, and the other end of the second spring is connected with the mass block. The first spring and the second spring are in the compressed state. The energy dissipation vibrator organically combines the traditional antiresonance principle, the deformation energy-absorbing principle and the standing wave principle together, and integrates and has multiple advantages of various single principles.

Description

technical field [0001] The invention relates to the technical field of underground engineering, in particular to an energy dissipation vibrator and a dynamic protection system and method for a standing wave area. Background technique [0002] Under the background of the country's vigorous construction of underground projects such as subways, highway tunnels, and underground expressways, it is necessary to study the dynamic protection issues such as seismic / explosion resistance of underground projects. [0003] The current anti-seismic / anti-explosion technology of underground engineering mainly optimizes the design from two aspects of structure and material. Structure-based anti-seismic / anti-explosion technology is mainly realized by adopting structural forms that are conducive to stress wave reflection, diffraction and scattering, such as circular structures, arch structures, structures with structural holes, and multi-layer composite structures. Material-based dynamic prot...
