Background technique

There are a large number of tunnel projects in the field of water conservancy, hydropower and transportation in my country. Geological disasters in tunnel engineering are the key factors restricting tunnel construction. Often due to the unknown geological conditions in front of the tunnel, unpredictable geological disasters often occur, such as water inrush, mud inrush, collapse, rock formation, etc. Explosion and harmful gases, etc. Once a disaster occurs, the normal construction will be interrupted due to the destruction of machinery and equipment, flooding of tunnels, or severe casualties and huge economic losses, and even some underground projects will be forced to suspend construction or reroute.

It is well known that one of the most important tasks for any geotechnical-related engineering or scientific problem is to model and numerically represent the spatial distribution of geotechnical bodies (mechanics). The formation and evolution history of geological rock and soil mass is generally long and changeable, which results in the complexity and diversity of spatial distribution of rock and soil mass with various physical and mechanical properties. Therefore, one of the most common and important engineering tasks in construction engineering such as engineering surveys, foundation engineering, slope reinforcement, etc. when drilling holes in the earth using a drilling machine or drilling machine. Borehole records for engineering reconnaissance drilling are generally compiled by geological and geotechnical engineers based on collected cores and soil samples. According to these obtained original data, people can make reasonable extrapolation on the basis of existing experience and understanding, so as to establish a space and peace section model of ground mechanics, and apply the model in digital representation to design, production and construction. However, construction Logging of boreholes is generally documented by the drilling operator, and data on the use of digital monitors to record and monitor boreholes and live drilling is scarce.
