BFRPs has the advantages of light weight, corrosion resistance and good durability compared with steels, which is expected to solve the above problems when applied to shield tunnelling segments. In this study, the preparation process of basalt fiber-reinforced polymer (BFRP) bar reinforced shield tunnelling segment (BSTS) is described in detail against the background of shield tunnelling segment actually used in engineering. In order to investigate the blast resistance performance of the BSTS under blast loading, the test process is simulated using LS-DYNA finite element analysis software. The results show that the main damage modes of BSTS under proximity blast loading can be categorized as cratering, cracking, spalling and rupture. With the decreasing Scaled distance, the top surface blast crater is expanding, and the concrete on the back surface is further spalling, showing more obvious local damage characteristics. Provide reference for the design of shield tunnel lining structure's anti-explosion performance.

The dynamic response of concrete components under blast loading is of great military and social importance. Based on the continuum-discontinuum element method and fluid–structure coupling algorithm, the dynamic response of concrete slab is simulated and analyzed. First, a full-time numerical simulation is conducted. Then, the displacement and crack characteristics of concrete slab are analyzed quantitatively. The result indicates that the displacement is distributed in a circular pattern, and the maximum value is located at the center of concrete slab. The crack ratio increases gradually with the growth of time, while the growth rate is not a constant value. The fracture type of concrete slab includes tensile fracture and shear fracture, the interface at the center mainly undergoes shear fracture, and a small number of interface on the outside of cracked region suffers tensile fracture.
