    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!

    The kernel research achievement A BIM-based Dynamic Construction Management System (4D-BIM) has been added to the "Products" section.

    The system combines the BIM and 4D technologies and adopts the international standard IFC (Industry Foundation Classes). By studying the IFC-based structure, definition and modeling/sharing/integrating technologies for BIM, the construction model and the site model are linked to the schedule, resource, safety, quality and cost information to eastablish the IFC-based 4D-BIM model. Then the 4D-BIM model enables BIM-based integrated management, realtime control and dynamic simulation for scheudle, resource&cost, safety&quality, site&facility of a construction porject. Up to now, more functions have been embedded in the system to be suitable to not only buildings, but also bridges, wind plants, metros, tunnels, highways and MEP engineerings, etc.
