Description

Technical Field

[0001] The present invention relates to the technical field of geological logging, and in particular to a geological logging method based on real-time data acquisition. Background Art

[0002] Geological cataloging is a fundamental tool in geological research. It refers to the systematic and comprehensive description and recording of geological phenomena, encompassing all aspects of strata, rocks, minerals, fossils, and structures. Geological cataloging requires expertise in multiple fields, including stratigraphy, petrology, and mineralogy. Stratigraphy studies the formation, distribution, and evolution of strata; petrology focuses on the composition, structure, and texture of rocks, as well as their genesis; and mineralogy focuses on the composition, structure, properties, and distribution of minerals in nature. Geological cataloging is not only a tool for scientific research but also a treasure of human culture. Throughout Chinese history, ancient people's observations and records of geological phenomena date back thousands of years. For example, the descriptions of mountain and river landforms and mineral distribution in the Classic of Mountains and Seas, as well as the detailed records of rivers, lakes, springs, and other water bodies in the Water Classic, demonstrate the ancient Chinese's interest in and understanding of geological phenomena. These historic geological cataloging achievements have provided valuable geological information for future generations.

[0003] At present, the timeliness and effectiveness of traditional geological cataloging methods in investigating landslide phenomena are relatively poor. After collecting existing geological characteristic factors, the geological cataloging information cannot be updated in a timely manner, and it is impossible to study disaster-causing factors in combination with regional geological characteristics and put forward professional prevention and control engineering suggestions.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0035] Because traditional geological logging methods are less effective in detecting landslides, after collecting existing geological characteristics, it is impossible to update geological logging information in a timely manner, study disaster-causing factors in combination with regional geological characteristics, and propose professional prevention and control engineering suggestions.

[0038] Step 2: Collect historical topographic data of the target survey area, and survey and collect landform slope data, surface water data, groundwater data, and rock and soil distribution data of the target survey area. Then upload the data to the data acquisition module in real time via the network. The data acquisition module will compile the uploaded geological environment data into an environmental data set. Specifically, the TRIMBLE:R4 RTK measurement equipment is used to collect the survey data, and centimeter-level positioning accuracy is obtained in real time outdoors to ensure the reliability of the environmental data.
