<p>The pumped storage water conveyance roadways constructed based on abandoned coal mine goaf areas are subjected to the long-term coupled effects of hydraulic pressure and in-situ stress. Under such hydro-mechanical coupling conditions, fractures in the surrounding rock are highly developed, resulting in pronounced structural degradation and time-dependent deformation. To investigate the creep mechanical behavior and failure mechanism of double-fractured rock under constant hydro-mechanical coupling, triaxial creep tests were performed on rock-like specimens with different fracture inclinations under various water pressures. The effects of fracture geometry and water pressure on deformation stages, strain evolution, creep rate, and long-term strength were systematically analyzed. Results show that higher water pressure markedly increases creep strain at the same load level, advances the onset of the accelerated creep stage, and reduces the load level corresponding to failure. Fracture inclination significantly affects creep strain accumulation and rate evolution, closely related to crack propagation and rock bridge failure. Long-term strength decreases with increasing water pressure, with the largest reduction observed at fracture inclinations of 30°-60°. Deformation and failure mechanisms are jointly governed by water pressure and fracture geometry, with fracture inclination controlling the dominant failure surface. Based on these findings, nonlinear creep damage constitutive models considering real hydro-mechanical coupling were developed for both intact and double-fractured specimens, achieving fitting accuracy of R² &gt; 0.90. The results provide theoretical guidance for long-term stability evaluation and design of surrounding rock in water storage roadways.</p>
