Tunnelling and Underground Space Technology(2019)
摘要
•An innovative method to install a separate sewer systems.•Addressing the challenges associated with constructing a separate sewer system in narrow streets.•Providing additional space for other infrastructure services.•The structural performance of using one trench to accommodate two separate pipes in a one-over-one configuration.•3D FE models were utilized to test the behaviours of pipes in the proposed configuration methods.
