Segapõhine

Segapõhine refers to a mixed or hybrid foundation in Estonian. This term is often used in construction and civil engineering to describe a foundation system that combines different types of structural elements to support a building or other structure. The rationale behind using a segapõhine foundation is typically to optimize performance, cost-effectiveness, or to address specific site conditions that might not be ideally suited to a single foundation type.

Common combinations found in a segapõhine foundation can include elements like shallow foundations such as strip or pad footings, coupled with deep foundations like piles or caissons. For instance, in areas with varying soil bearing capacities across a site, some parts of a structure might be supported by shallow footings where the soil is stable, while other areas requiring deeper support might utilize piles driven to bedrock or a competent soil layer.

Another scenario for a segapõhine approach might involve using a raft foundation in conjunction with piles. A raft foundation spreads the load over a large area, which is beneficial for soft soils. However, if the structure is particularly heavy or if there are concerns about settlement, piles can be incorporated to transfer some of the load to deeper, more stable strata. The design of a segapõhine foundation requires careful analysis by structural engineers to ensure the stability and load-bearing capacity of the entire system, considering the interaction between the different foundation elements and the surrounding soil.
