Ballastikihti

Ballastikihti is a term used in the field of geotechnical engineering to describe a layer of soil or rock that is used to support the weight of a structure, such as a bridge or a building, by providing additional stability and reducing the load on the underlying soil. This layer is typically composed of materials with high density and low compressibility, such as gravel, sand, or crushed stone. The purpose of ballastikihti is to distribute the load evenly across a larger area, thereby minimizing the risk of settlement or failure of the structure.

The installation of ballastikihti involves the placement of the selected material in a controlled manner, often using specialized equipment such as vibratory rollers or compactors. The thickness and composition of the ballast layer are carefully designed based on the specific requirements of the structure and the characteristics of the underlying soil. In some cases, geotechnical investigations may be conducted to assess the soil conditions and determine the appropriate design parameters for the ballast layer.

Ballastikihti is commonly used in various construction projects, including road and railway embankments, foundations for heavy machinery, and support structures for large-scale infrastructure. Its effectiveness in providing a stable and load-bearing base makes it a valuable component in the design and construction of many engineering projects.
