Table 1: Information on rockburst hazards in selected deeply buried hard rock TBM tunnel projects. and blasting parameters; and evaluated the effectiveness of the release effect. However, the TBM cutter head structure usually limits the layout of stress release boreholes, so the application of ARHs in TBM-constructed tunnels is rare. As a rare case, water hammer drill ASRBs were constructed at K40+613 in the TBM-constructed tunnel section of the Hanjiang-Weihe River Diversion Project [29; 30]. [PERSON] carried out microseismic monitoring and numerical simulation, and the results showed that ASRBs release energy within the rock mass to some extent [30]. There are very limited studies on the ASRB design method, most of which focus on the analysis of the correlation between the stress release effect and SRB parameters such as diameter, depth, spacing, and shape. From a test perspective, [PERSON], [PERSON] [31] conducted indoor experiments on samples with different borehole sizes, depths, and spacing. They obtained the correlation between borehole parameters and stress release effects. [PERSON], [PERSON] [32] conducted indoor experiments and numerical simulations to explore the effects of the height and width of square boreholes on strain energy release. [PERSON], [PERSON] [33] conducted indoor uniaxial compression tests on prefabricated rock samples with different pore shapes, revealing the internal mechanism of drilling pressure release. From a numerical analysis point of view, [PERSON], [PERSON] [34] discussed the effect of SRBs on the stress release and energy dissipation of rocks surrounding an auxiliary tunnel of the Jinping II Hydropower Station. The stress release and energy dissipation effects of an SRB under different schemes from the perspective of the plastic zone, damaged zone, and accumulated energy were analyzed. [PERSON], [PERSON] [35] discussed the stress release mechanism of large-diameter drilling from the perspective of indoor testing and particle flow code (PFC) simulation and analyzed the influence of borehole diameter, borehole depth, and borehole spacing parameters on the stress release effect. [PERSON], [PERSON] [36] revealed the stress release mechanism of SRBs using a numerical simulation method and discussed the influence of three borehole parameters, namely, borehole diameter, borehole depth, and borehole spacing, on the stress release effect. However, in practical engineering applications, drilling parameters usually rely on empirical values, lacking reliable design and analysis methods [21].
