The application status of BIM technology in building structural design is summarized, and the application of collaborative design of Revit platform is discussed in this paper. Specific process of collaborative design for structural specialty is compared with conventional design process. After that, the characteristics of the software for structural construction drawing design based on Revit are compared. Three structural design methods based on BIM technology are summarized and thier advantages and disadvantages are analyzed.Finally, a practical project is analyzed by using BIM construction drawing tool software. The results show that:the BIM construction drawing design can be realized by the structure calculation software based on Revit, the large volume of building requires high computer performance, the selection of collaborative mode has great influence on the design process and results, and the stability of the structure calculation model derived from Revit structural construction drawing software needs to be improved.

As an important part of building industry transformation upgrade, BIM technology was used widely in large complicated project.The subway station project is characterized by huge quantity, complex pipeline systems, and difficult equipment installation.This paper introduces the concrete application in three phases like design phase, construction phase and maintenance phase.BIM technology was introduced into the project all-around, which help build the subway station all professional model to realize the professional 3D visualization and make organic connection of each professional flat vertical profile control drawing information is established.Collisions inspection among different professions, the virtual simulation and 4D virtual construction technologies will improve the working efficiency and save the project cost.BIM technology in the application of subway station project can help promote BIM technology to widely use in complicated engineering project and play a reference.

Based on the railway embankment health monitoring, this study developed an embankment small deformation monitoring system based on FDM (Fused Deposition Modeling) and FBG (Fiber Bragg Grating) technology. Using FDM technology and FBG sensing technology to design the FBG sensor monitoring model with package and anchor plate, the relationship between load and soil displacement can be obtained by calibration test. The results show that the displacement has a good linear relationship with the load, and the correlation coefficient reaches 0.99. The test measured a maximum displacement of 0.25 mm, a minimum displacement of 0.05 mm, a sensor sensitivity of 4 nm/mm, and a minimum resolution of 0.62 μm. The feasibility of the sensor is tested by two test conditions, including monitoring the displacement of the embankment under static and dynamic loads. The monitoring data under static load shows that the wavelength and displacement increase stepwise with time, and the minimum displacement of the embankment is successfully collected, which reaches 0.004 mm. The dynamic load monitoring test results show that the sensor can quickly reflect the vertical pressure generated by the vehicle model load.

BIM Technology was applied in the construction of Guangzhou metro line 6 second phase of the mechanical and electrical installation and public area decoration project. The different profession construction units completed the construction model according to the design drawings, the site supervision organized the various professional construction units to finish the model merge. There were many problems in model merging process. This article gives a brief analysis and puts forward feasible solutions, and looks forward to the model merge in the late subway line construction.

The mechanical and electrical installation engineering of subway station involves ventilation and air conditioning, water supply and drainage and fire-fighting, low-voltage distribution and lighting, and weak current systems. The comprehensive arrangement of four major professional pipelines are the difficult part of the construction design stage. The line between different professional configuration designs needs to meet design and construction specifications and maintenance requirements. This article mainly discusses the collision between professional models and introduces professional model collision point classification, collision detection process, setting of test condition, and collision preparation of reports. From the summaries of the reports of Suyuan station, it shows that air duct, the building structure and electric bridge need to be considered much more than others. In the end, the article summerizes the application prospect and existing problems of BIM technology in electromechanical integrated pipeline configuration of subway stations.
