This paper discusses the reasonable clear spacing of twin-tunnels in weak surrounding rock, addressing the urgent need for effective solutions due to increasing occurrences of small clear spacing tunnels. It presents an analytical solution based on pressure-arch theory and numerical simulations to determine the loosening pressure on surrounding rock, revealing that the clear spacing significantly affects the stability and safety of the tunnels. The findings are validated with in-site data, establishing a fr
