泉域富水环境下大明湖区段地铁车站基于BIM技术的保泉与文保方案研究OA

Focusing on the construction of a subway mined station in a water-rich karst spring region,this paper takes Daming Lake section of Jinan Rail Transit Line 6 as the research object to explore the reasonable station solutions under the requirements of ecological spring protection and cultural heritage preservation.In view of the challenges such as the sensitivity of groundwater in the spring region and conflicts between cultural preservation and construction,three innovative systems are proposed:a non-dewatering excavation method,utilizing the"pipe-roof support+full-section precise grouting"technique to achieve zero disturbance to groundwater during the excavation of a 30-meter-deep foundation pit and mined sections.The establishment of a multi-dimensional"geology-hydrology-structure-cultural preservation"model enables the simulation of construction scheme and the optimization of process parameters based on BIM.The adoption of a layered composite design that integrates the subway station with cultural landmarks such as heritage sites,achieves the three-dimensional fusion of cultural preservation and functionality while enhancing the cultural value of underground space.This forms a"technological innovation-digital empowerment-cultural preservation upgrading"solution,providing a technical paradigm for subway construction in spring regions and promoting the coordinated development of urban rail transit and the ecological environment.
