## 1 Introduction
[PERSON] [4] studied the anti-explosion performances of the two types of surrounding rock reinforcement chamber structures under the action of plane charge explosion stress waves by using explosion model test techniques, and found that the full-length bonded anchor reinforcement strategy had a better effect on reducing peak displacement than the strain and acceleration of the vault. In practical engineering applications, when the underground structure is in a poor geological and lithological environment, the surrounding rock reinforcement layer no longer satisfies the requirement of structural resistance. In order to ensure the static stability of the surrounding rock and enhance its dynamic load resistance, it is necessary to build reinforced concrete structures outside the surrounding rock reinforcement layer to improve the structural resistance. Based on the matrix force method, [PERSON] [5] proposed a calculation method for the dynamic response of the circular tunnel lining structure, and obtained that the maximum displacement of the circular tunnel lining structure under the action of explosion seismic waves occurred at the top and bottom. When the wave impedance ratio between the surrounding rock and the lining is greater than 0.25, the influence of surrounding rock on the dynamic response of the lining structure is reduced. [PERSON] [6] compared and analyzed the peak stress and deformation characteristics around the unlined chamber and the lined chamber under the condition of plane charge loading by using the explosion model test techniques, and found that the lining support structure was of an important technical measure to improve the resistance grade of the engineering structure. At present, there are two main ways to improve the resistance of underground engineering structures. The first is to use the high-strength materials as the main structural materials to improve the structural strength, and the second is to backfill the soft material (energy absorbing material) between the surrounding rock and the supporting structure to weaken the intensity of explosion wave, which then indirectly results in improving the resistance of the engineering structure. The high-performance concrete has some excellent properties, such as high compressive strength, toughness and durability, which are important aspects for the development of concrete material. Thus, comparing with the C30 concrete structure, the high-performance concrete structure has many advantages in the properties of anti-explosion and anti-penetration [7; 8; 9]. A lot of research reports indicate that the addition of steel fiber reduces the risk of explosion spalling in concrete. The presence of steel fiber can bridge microcracks inside concrete, and improve the tensile strength of concrete and the overall bearing capacity of the structure [10; 11; 12]. In addition, many studies have shown that under the explosion loading, the Steel Fiber Reinforced Concrete (SFRC) exhibits better explosion resistance than the ordinary concrete, and can more effectively prevent the risk of explosion spalling [13; 14; 15; 16]. [PERSON] [17] carried out an explosion test for the steel-fiber-reinforced high-strength concrete, and the results showed that the SFRC had a significant anti-seismic collapse performance effect, and its anti-seismic collapse performance mainly depended on the tensile strength of the concrete. [PERSON] [18; 19; 20; 21] conducted some extensive static and dynamic tests for the UHP-SFRC structural members added with steel fiber, and found that the steel fiber could provide bridging action and reduce the structural crack width during the structural damage. The energy dissipation characteristics of the weak interlayer in the rock have a considerable influence on the attenuation of stress waves. Because the porosity is large, it is generally compressible. Only when the medium is compacted, the stress wave can cross the layer. The larger the porosity is, the faster the attenuation of stress waves [22].
