A new research article entitled "Bibliometric review of visual computing in the construction industry" has been published in Visual Computing for Industry, Biomedicine, and Art. 

In the construction area, visuals such as drawings, photos, videos, and 3D models, play a significant role in the design, build and maintenance of a facility, bringing efficiency to generate, transfer, and store information. Advanced visual computing techniques facilitate the understanding of design contents, work plans, and other types of information shared in the construction industry. Automatic visual data collection and analysis provide many possibilities to the construction industry and a large number of works have investigated how visual computing can improve construction management processes and other problems in the construction area. This study uses bibliometric approaches to review the works published to date, and analyses the development of knowledge, significant research results, and trends.

A new research article entitled “A Hybrid Data Mining Method for Tunnel Engineering Based on Real-Time Monitoring Data from Tunnel Boring Machines” has been online published in IEEE Access.

This study achieved automatic analysis of TBM real-time monitoring data based on a hybrid data mining (DM) model to ensure safety management of tunnel construction. Three different DM techniques that were designed for different safety management objectives were combined to form the hybrid DM framework and support safety management process. In order to provide people with the experience required for on-site abnormal judgement, the association rule algorithm is carried out to extract relationships among TBM parameters. To supplement the formation information required for construction decision-making process, a decision tree model is developed to classify formation data. Finally, the rate of penetration (ROP) is evaluated by BP neural network and convolutional neural network to find abnormal data and give early warning. The feasibility of the method was validated by on-site construction data. The first author of the paper is Mr. Leng, the second author is associate Prof. Lin, and the fourth author is Dr. Shen. In addition, we also acknowledge the Metro Supervision Department of the Guangzhou Metro for providing support.

A new research article entitled "Active Earth Pressure of Limited C-φ Soil Based on Improved Soil Arching Effect" has been published in Applied Sciences. This study was a collaboration between the research group and Shenzhen Metro Group Co., Ltd. The c-φ soil of limited width between a deep retaining structure and the adjacent large rigidity existing underground structure is very common in a dense underground environment. An analytical model for the earth pressure distribution and for the width boundary of a limited c-φ soil by considering soil arching effect was proposed in this study. The analytical model was verified by comparing with numerical simulations, traditional theoretical methods and model tests. The smaller of the limited soil width, the more sensitive it is to earth pressure. Ignoring the influence of soil cohesion and the limited width will exponentially reduce the overall stability of the retaining structure and increase the risk of accidents.

The novel coronavirus (COVID-19) pandemic is the most serious public health emergency in China since its establishment. In the severe struggle against the epidemic, a number of medical staff, cadres and workers, and a large number of communities unfortunately died on duty. Today is the Tomb Sweeping Day in China, therefore the dead compatriots were deeply mourned by the Chinese people of all nationalities throughout the country.

The dead rest in peace, and survivor endeavour!
