Special Issue Information

Dear Colleagues,

The disaster monitoring of rock engineering plays a key part in the construction of major projects, especially for the deep rock mass in the tunnel of hydroelectric engineering and railway construction. The problem of safe construction and disaster monitoring deeply influences project progress, efficiency, and operation cost. This problem may be affected by many aspects, but the interactions between soil, rock, and groundwater are a vital part of the precipitating factors for disaster. The monitoring and analysis by the use of different methods or devices often focus on interactions and fractures, such as micro-seismic monitoring, ultrasonic investigation, and borehole cameras. All these monitoring and analysis methods could provide a way to solve the disaster monitoring problem and promote technical development.

This Special Issue is open to papers addressing the monitoring and analysis of engineering disasters, especially for interaction problems between soil, rock, and groundwater during the construction of deep geotechnical engineering and geomechanics. We aim to publish contributions on novel disaster monitoring and analysis methods, including new constitutive schemes, particularly the advanced monitoring approaches of micro-seismic monitoring, ultrasonic investigation, and borehole cameras. Practical applications of these advanced approaches to real disaster monitoring problems are particularly welcome.

Digital panoramic borehole imaging technology has been widely used in the practice of drilling engineering. Based on many high-definition panoramic borehole images obtained by the borehole imaging system, this paper puts forward an automatic recognition method based on clustering and characteristic functions to perform intelligent analysis and automatic interpretation researches, and successfully applied to the analysis of the borehole images obtained at the Wudongde Hydropower Station in the south-west of China. The results show that the automatic recognition method can fully and quickly automatically identify most of the important structural planes and their position, dip, dip angle and gap width and other characteristic parameter information in the entire borehole image. The recognition rate of the main structural plane is about 90%. The accuracy rate is about 85%, the total time cost is about 3 h, and the accuracy deviation is less than 4% among the 12 boreholes with a depth of about 50 m. The application of automatic recognition technology to the panoramic borehole image can greatly improve work efficiency, reduce the time cost, and avoid the interference caused by humans, making it possible to automatically recognize the structural plane parameters of the full-hole image.
