Research On The Application Of BIM In Foundation Pit Engineering

In industry rapid development project complexity increases at the same time,the number of participants and to participate in the cooperation between departments demand is higher and higher,but the application of BIM technology already can calmly face the problem of rapid development,was tested in many projects.Due to the particularity of foundation pit engineering,the traditional design and construction of two-dimensional drawings under the carrier's support mechanism limits the development of BIM technology in the project,there are also many problems in the construction schedule,processes and so on.This paper combines the building information model with foundation pit engineering to explore the specific application of BIM technology in foundation pit engineering.So as to determine the research direction and content.The paper starts with the basic concepts of BIM,introduces the application of BIM at this stage,analyzes the differences in the tools,methods,and structures of construction engineering under BIM technology and CAD technology,and introduces the factors that restrict the current BIM technology.The standard of BIM components begins with the application of BIM in foundation pit engineering.A BIM component named standard and proposed the establishment of the views of the component libraryThe paper uses Revit to establish a core model and then uses Navisworks to explore the use of BIM technology in the foundation pit engineering feasibility study,design,construction and operation and maintenance phase of the application of the exploration to the core of Revit on the basis of modeling,try to establish a naming standard at the same time a method to quickly establish a vertical excavation pit model was created,meanwhile a kind of auxiliary means of risk accident control is put forward.Taking the foundation pit engineering project of a subway station in Zhengzhou as an example,this paper uses BIM technology to model the foundation pit support structure,and uses the existing software to calculate the structural stability to guide the design and realize the foundation pit for the design process.The excavation,rebar layout,simulation of construction process,realization of project volume statistics,and collision checking between components are used in the foundation pit project.
