To improve digital design
quality and efficiency for immersed-tube
tunnels, a combined approach of standard formulation and software programming
is used to develop a digital design system for the civil structure of immersed-tube tunnels. First, the authors summarize and analyze practical
experiences in immersed-tube tunnel design, distilling
the critical requirements for digital design processes, leading to the
formulation and establishment of the Standard for Delivery of Immersed Tunnel Digital Design.
Subsequently, utilizing this standard as a reference, the authors proceed to
develop a digital design system for the civil structure of immersed-tube tunnels, which is tested and validated through implementation
in multiple real-world engineering projects. According
to the digital design process, the digital design system for the civil
structure of immersed-tube tunnels is divided into
three modules: digital design module, calculation and analysis module, and
information addition module. The digital design module analyzes the design
parameters entered by users and automatically generates models, drawings, and
engineering quantity tables. The calculation and analysis module has built-in formula verification functions such as anti-floating and freeboard calculation, and establishes a data linkage
relationship between the design parameters in the digital design module and the
existing finite element calculation software for immersed-tube tunnels, thereby improving calculation efficiency. The information
addition module integrates the classification coding and information addition
rules of the model into the software, achieving rapid addition of
classification coding and information.
