In the bustling cityscape of Shanghai, where urban development often collides with the need for efficient transportation, researchers have made significant strides in optimizing land use through innovative structural design. A recent study led by TAN Qifeng from the China Railway Shanghai Design Institute Group Co, Ltd, delves into the complexities of constructing underground railway depots with the foresight of potential overlying property development. This research, published in ‘Chengshi guidao jiaotong yanjiu’—translated as ‘Urban Traffic Research’—highlights the intersection of transportation infrastructure and urban planning.
The study focuses on the Shenkun Road Parking Lot Project, part of the Shanghai City Railway Airport Link Line, which serves as a critical case study. TAN emphasizes the importance of integrating railway depots into the urban fabric without disrupting the existing landscape. “To enhance land use efficiency and minimize urban fragmentation, it’s crucial that we design structures that not only serve their purpose but also accommodate future developments,” he stated.
The challenges of constructing an underground vehicle depot are multifaceted. Unlike traditional ground-level depots, these subterranean structures face unique issues such as temperature-induced cracking, waterproofing, and the complexities of discontinuous construction. TAN’s research proposes a series of advanced technologies to mitigate these risks. For instance, anti-cracking reinforcing bars are strategically placed based on temperature stress analyses of super-long, jointless cover plates. This innovation is expected to significantly reduce the likelihood of concrete cracks and subsequent water leakage, a common concern in underground constructions.
Moreover, the study addresses potential water leakage through alternative waterproofing solutions for side walls and bottom plates. “We must consider construction quality and maintenance conditions to ensure the longevity of these structures,” TAN explains. The research also introduces a hybrid approach that combines temporary anti-floating measures with construction load reservations, allowing for asynchronous building processes between the depot and any future developments above.
The implications of this research extend beyond mere structural integrity. By enhancing the efficiency of urban land use, it paves the way for increased commercial opportunities in densely populated areas. As cities continue to grow, the demand for integrated transport solutions will rise, making studies like TAN’s pivotal for the construction sector. The ability to design multifunctional spaces that accommodate both transportation needs and urban development will be a game-changer.
As urban planners and construction firms look to the future, TAN’s work serves as a blueprint for how infrastructure can harmoniously coexist with urban landscapes. This innovative approach not only addresses immediate engineering challenges but also sets the stage for sustainable urban growth, proving that thoughtful design can lead to thriving, interconnected cities.
