Research on the development and application of digital design platform for shield tunnel linings
摘要
Abstract
In order to reduce costs and increase efficiency for shield tunnel structural design,a web-based digital design platform of shield tunnel linings(named TIM-SAP)was developed based on the B/S architecture.The TIM-SAP focused on the functional interaction design and algorithm development for shield tunnel lining structure design.It was based on the modules of generative modeling,meshing division,structural calculations,post-rendering processing and designs program flows,functions,and invocation interface.TIM-SAP has eight functions consisting of shield modeling,assembly,tunnel modeling,earth load calculation,structural calculation,reinforcement design,and drawing.It can provide the services of modeling,calculating,reinforcement design,and drawings.The main technologies used in these function developments included parametric modeling for B-rep,KNN-based surrounding soil analysis,parametric structural calculation,and DT-RF-based reinforcement scheme generation.The calculation results of TIM-SAP were first adjusted through Wuhan Metro 12th Line design project,followed by its application in the design project of the Wuhan New Port Line shield tunnel.The results indicate that it can enhance digital design platforms or systems development by integrating existing mature functional modules in civil engineering design.After adjusting in Wuhan Metro 12th Line,the calculation results of TIM-SAP can be consistent with those of existing tools.In the context of its implementation in the Wuhan Metro Xingang Line design project,the TIM-SAP has the capacity to circumvent some intricate operational tasks such as mesh handling,optimization of convergence,table searching,among others.It offers'one-click'model generation,thereby facilitating graphical illustrations and three-dimensional representations in pertinent design documentation.Upon comparative evaluation with the extant software,TIM-SAP potentiates a reduction in time expenditure ranging from 8 to 60 minutes.This study has the potential to augment and enhance the digital and automated design proficiency in underground engineering.关键词
