Abstract

In the context of urbanization and population growth posing challenges to urban space, the development of parallel tunnel systems has become necessary to improve the efficient transportation of passengers. Recent studies have not only focused on analyzing individual tunnels but have also expanded to understand the interaction between closely spaced tunnels using methods such as numerical modeling and finite element analysis. This paper examines the stability of parallel tunnels under increasing shear strength in cohesive soil conditions using the NGI-ADP soil model through Plaxis 2D V20 software. Additionally, the failure mechanism of parallel tunnels in cohesive soil with increasing shear strength is also demonstrated to assess the influence of all other parameters (depth-to-span ratio, distance between two tunnels). The research results contribute significantly to the design and construction of parallel tunnels while optimizing solutions for complex geological conditions.
