Hydrogeological conditions This is an important engineering geological factor. Groundwater is an important factor to reduce the stability of rock and soil. In some cases, it will erode some parts of buildings (such as foundations) and affect the safety of buildings. It includes the source, burial, distribution, dynamics and water quality of groundwater.
Geological conditions:
Engineering geological conditions are the geological environment of engineering activities, which can be understood as the synthesis of various factors in the geological environment of the area where the engineering building is located. Generally speaking, it includes the types of rock and soil (rock and soil) and its engineering properties, geological structure, topography, hydrogeological conditions, surface geological functions and natural building materials.
Types and engineering properties of rock and soil are the most basic engineering geological factors, including their genesis, age, lithology, occurrence, diagenetic characteristics, metamorphic degree, weathering characteristics, weak interlayer and contact zone, physical and mechanical properties, etc.
Geological structure Geological structure is the basic object of engineering geological work research, including the distribution and characteristics of folds, faults and joint structures. Geological structures, especially large-scale dominant faults in the new era, have a controlling effect on earthquakes and other disasters, and are of great significance to the safety, stability, settlement and deformation of buildings.
