"substructure" 的定义和意义

What is a "substructure"?

A substructure is the portion of a building or structure that is located below the ground level, providing support and stability for the above-ground components. It typically includes elements such as foundations, basements, and footings, which transfer the weight of the structure to the soil or bedrock below. The design of the substructure is crucial for ensuring that the building can withstand various loads, including weight, pressure, and environmental forces. Proper construction of the substructure helps prevent settling, shifting, or other structural issues, making it an essential aspect of any construction project.
