摘要：AbstractA well-designed cut-hole layout is crucial for improving drilling and blasting efficiency in deep underground engineering. For this purpose, this study investigates the patterns of blast-induced rock damage under various cut-hole layouts and ground stress conditions through numerical simulations and field tests. The key cut-hole parameters include uncoupling coefficients (K), the empty ...

关键词：Temperaturedependent shear behavior and constitutive model of the rockconcrete interface
摘要：AbstractShear tests were conducted at a shear rate of 1 mm/min and a shear displacement of 10 mm to investigate the effect of temperature on the shear behavior of the rock–concrete interface, with the aim of revealing the interaction between the surrounding rock and the lining during tunnel fires. The experimental results obtained several key findings: The mechanical properties of rock and c...
