Abstract:
In the development process of digital design and construction technology, due to differences in information architecture, management levels and work modes, it is difficult to form a benign closed loop among construction parties in terms of undertaking the construction phase of 2D and 3D design results and the installation information in the operation and maintenance phase. This paper proposes to establish an integrated application system based on building digital design and intelligent construction to realize the whole industry chain integration from production endpoint to application endpoint. In the design stage, digital standard design is realized by establishing modern industrialized architectural design standards, component libraries and supporting tools. In the production stage, the direct conversion of digital results is realized through the research and development of construction methods and equipment matching the digital design results. The data management mode based on discretization is adopted.Under the standard data sharing, it adopts the method of layered independent management at each stage and inter-layer coding, takes into account the independence and interoperability of multiple platforms, and realizes the seamless implementation of the entire process of digital design results and digital integration of the industrial chain.

Abstract:
With the rapid construction of metro and the establishment of hazard troubleshooting system, a large number of hazard records during the construction are saved in the system. However, there are many hazard records abundant in information, and they need to be analyzed on the basis of guidelines and expert experience seriously, requiring significant labor cost. In order to improve the efficiency of hazard troubleshooting process and the level of safety management decision-making, this paper presents a novel framework that combines text mining and visualization technologies, providing the ability to analyze hazard records automatically. The framework comprises the following four-step modelling approach.Firstly, an overview of hazard records is provided through the quantitative analysis by TF-IDF technology of keywords. Secondly, the thematic information and key points hidden in the large-scale hazard troubleshooting corpus are identified using a Latent Dirichlet Allocation algorithm. Thirdly, a visual overview of hazard records is generated through the quantitative analysis by Word Cloud technology of keywords.Finally, a Word Co-occurrence Network is produced to determine the interrelations between hazard categories and sites. The framework has been used and verified in the analysis of hazard troubleshooting records of Wuhan metro in 2016-2018, showing it can mine 34 categories of hazard troubleshooting keys and visual information.

Abstract:
The characteristics of BIM technology are very helpful to improve the efficiency and correctness of pipeline integrated work. BIM software is excellent in comprehensive collision inspection, solving the bottleneck of floor net height, and three-dimensional mapping, which can effectively reduce errors in the drawings, ensure the construction period and improve efficiency. Common BIM software such as Revit has some shortcomings in localization and ease of use. Easy-building software makes a powerful supplement in this respect, not only improves the efficiency of die turning, but also closely combines the design process, provides a variety of batch modeling and pipeline comprehensive adjustment functions, and makes a useful exploration in the customization of complex tables. Easy-building software provides more support for the wide application of BIM in pipeline synthesis, and its research and development ideas and exploration process have a certain reference value.

Abstract:
Digital architecture refers to buildings that use digital information technology for design, construction, operation and maintenance. The parametric design of complex buildings must establish a complete geometric control system. Geometry is an important basic theory in parametric design. The language and methods of manifold geometry can be used to express and analyze curved three-dimensional geometric shapes conveniently. The concepts of"parallel"and"equidistant"of the curves on the curved surface provide us with a geometric intuitive and logical basis for the parametric design of geometric shapes. It focuses on the external equidistance between surfaces and the geodesic equidistance between curves on the surface, Levi-Civita parallel(intrinsic geometry)concepts, and expounds the geometric theory and methods in parametric design. The geometric methods used in the parametric design of the 2022 Hangzhou Asian Games table tennis competition venues and venue non-linear enclosure systems and roof systems are introduced.

Abstract:
In this paper, a pumping concrete model was established based on Workbench software. The finite element numerical simulation of the concrete pumping pipe and bracket was carried out by fluid-structure coupling technology. The static and dynamic characteristics of the bracket base under different stiffness during the pumping process were studied. The simulation results show that the method presented in this paper can carry out a more accurate numerical simulation of the force of the pipe bracket. The calculation results show that the best comprehensive effect can be achieved by improving the vibration absorber bracket to alleviate the vibration of the concrete pumping system and reduce the negative influence on the main structure. The research results of this paper have been successfully applied in Lu′an Gaotai community resettlement housing project and other projects.
