Is geological engineering (geotechnical drilling direction) geotechnical engineering?

It is a big category, belonging to the category of earth science, but geological engineering is different from geotechnical engineering.

Geological engineering includes: (1) geotechnical engineering types and their engineering geological properties; (2) Terrain conditions; (3) Geological structure and geostress; (4) Hydrogeological conditions; (5) Physical geological phenomena; (6) Natural building materials.

Geotechnical engineering is a science that uses engineering geology, soil mechanics and rock mechanics to solve engineering technical problems related to rocks and soils in various projects. According to the division of engineering construction stages, the work content can be divided into: geotechnical engineering investigation, geotechnical engineering design, geotechnical engineering management, geotechnical engineering monitoring and geotechnical engineering detection. The main research directions of this subject include: ① Urban underground space and underground engineering: taking urban underground space as the main body, studying various environmental geotechnical engineering problems in the process of underground space development and utilization, rational utilization strategy of underground space resources, design and calculation methods of various underground structures, and construction techniques of underground engineering (such as shallow buried and underground excavation, shield method, freezing method, precipitation and drainage method, immersed tube method, TBM method, etc.). ) and its optimization measures. (2) Slope and foundation pit engineering: Focus on the influence of foundation pit excavation (including foundation pit dewatering) on adjacent existing buildings and environment, the design and calculation theory and method of foundation pit supporting structure, the optimization design and reliability analysis technology of foundation pit supporting structure, the slope stability analysis theory and the development and application of new supporting technology. (3) Foundation and foundation engineering: research on foundation model, calculation method and parameters, new technology, new method and detection technology of foundation treatment, and mechanism and law of interaction between building foundation (such as strip foundation under column, cross foundation, raft foundation, box foundation and pile foundation) and superstructure.
