The content of engineering geological survey includes engineering geological survey and mapping, exploration and soil sampling, in-situ testing, indoor testing, etc. The engineering survey stage is generally divided into feasibility study survey stage, preliminary survey stage, and detailed survey stage.
The content of engineering geological survey includes engineering geological survey and mapping, exploration and soil sampling, in-situ testing, indoor testing, etc. The engineering survey stage is generally divided into feasibility study survey stage, preliminary survey stage, and detailed survey stage. Construction engineering survey refers to the activity of surveying, exploring, and testing terrain, geology, and hydrology to meet the needs of planning, design, construction, operation, and comprehensive management of engineering construction, and providing corresponding results and data. The investigation, design, processing, and monitoring activities in geotechnical engineering also fall within the scope of engineering investigation.
The content refers to geological mapping, exploration, indoor experiments, in-situ testing, etc. Conduct research and evaluation on the engineering geological conditions of the construction site. Provide necessary basis and parameters for the planning, design, and construction of project construction. Engineering geological survey conditions usually refer to the terrain, topography, geological structure, stratigraphic lithology, adverse geological phenomena, and hydrogeological conditions of the construction site. Mainly determined based on the type and scale of the project, survey stage, complexity and research status of the site engineering geology, engineering experience, building grade and structural characteristics, special requirements for foundation design and construction, etc.
It mainly includes the following five items:
1. Engineering geological survey technology can survey and collect existing geological, geomorphic, remote sensing photos, hydrological, meteorological, hydrogeological, seismic, engineering experience and other data in the research area, as well as existing survey reports;
2. Engineering geological survey and surveying;
3. Engineering geological exploration can be found in "Engineering Geological Surveying and Exploration";
4. Geotechnical testing and observation, including geotechnical testing and on-site prototype observation, rock mechanics testing and testing;
5. Compilation and compilation of engineering geological survey reports.
