"Architecture and Key Technologies of Big Data Platform for Highway Engineering Safety" has been first published in "Highway" on CNKI.

A large number of safety-related data will be generated during the execution of highway project, which is difficult to be systematically managed and fully utilized. Firstly, the classification, content and collection method of safety data in the process of highway construction are explained, and the characteristics and processing requirements of safety data are analyzed. Secondly, the architecture of big data platform for highway engineering safety is constructed, and the main levels of the platform are briefly explained. Finally, four key technologies of data pre-processing, data fusion and storage, data asset management, data analysis and mining for highway construction safety are analyzed in detail. The results show that:(1) The data of highway project implementation can be divided into seven categories, such as basic data, structure, machinery and equipment, etc., and data processing should meet the requirements, such as data extraction from heterogeneous data sources, etc.(2) The architecture of big data platform for highway project safety can be divided into six layers: data source layer, data access and pre-processinglayer, etc.(3) The key technologies of platform include data pre-processing, data fusion and storage, etc.

Note: Highway is a core journal of science and technology in the category of comprehensive technology.

"Web-oriented Dynamic 3D Visualization of Construction Processes" has been published in the journal of Construction Technology.

Aiming at the problems such as difficult to update, limited software environment or non-dynamic existing 3D visualization methods of construction processes, this paper proposes a web-oriented 3D dynamic visualization method of construction processes based on Cesium, including relative data models and animation definition, and a rapid 3D animation generation method based on frame segmentation and integration approaches. An efficiency test proves that the performance of frame segmentation and integration algorithms can meet the needs of general animation of construction processes. Besides, the above method is applied to show a case construction process on the web and to support online editing, playing, and updating of the process step animation, which verifies the feasibility of using the method in actual projects.

Simulation Analysis of the Dispersion of Typical Marine Pollutants by Fusion of Multiple Processes has been published in the journal Sustainability.

The rapid development of coastal economies has aggravated the problem of pollution in the coastal water bodies of various countries. Numerous incidents of massive-scale marine life deaths have been reported because of the excessive discharge of industrial and agricultural wastewater. To investigate the diffusion of typical pollutants after discharge, in this study, a multi-process fusion simulation analysis model of pollutants under the action of ocean currents was established based on the concentration analysis method. Furthermore, key technologies involved, such as the parameter value, data selection, and visualization, were investigated. The iterative analysis and programming realization of three independent sub-processes, such as pollutant diffusion and transport, and the drift path and concentration distribution of pollutants after their discharge into the sea, were visualized. The case study revealed that the increase in the concentration of pollutants in the ocean was affected by the diffusion sub-process, and the transport sub-process plays a critical role in the long-distance transport of pollutants. The proposed method can provide technical support for marine environmental risk assessment and dynamic tracking of marine pollutants.

Note: Sustainability is an important journal in the field of environmental science and ecology and a core journal in Q2, with an impact factor of 3.9 in 2023.
