A review of non-local, deep transport mechanisms in the atmosphere of Earth provides a good foundation for examining whether similar mechanisms are operating in the atmospheres of Mars and Titan. On Earth, deep convective clouds in the tropics constitute the upward branch of the Hadley Cell and provide a conduit through which energy, moisture, momentum, aerosols, and chemical species are moved ...

The effect of large deep foundation excavations on the surrounding existing tunnels is a problem that cannot be avoided in current construction background. This difficult to assess precisely, especially when geometry and pits complex. In this paper, three-dimensional (3D) finite element model has been developed based case containing four complex intersecting pit. used hardening soil with small-...

The existing green construction evaluation lacks dynamic nature. Based on the characteristics of urban deep foundation pit construction, PDCA cycle theory gives index weight based OWA operator, and establishes a model. BIM information technology is used to build platform Wuhan Yangtze River Shipping Center proves scientific nature evaluation.

This paper investigates the deformation characteristics and control methods of support structures during deep foundation pit excavation, using at Diejiao Station Foshan Metro Line 3 as a case study. A 3D nonlinear finite element software is employed for excavation simulation, adopting coupled pore fluid diffusion stress analysis. The numerical model verified by comparing field monitoring data w...
