Example (3.1): Settlements outside the foundation
In many situations, it becomes important to assess the behavior of a foundation due to its interaction with another neighboring foundation or external load. First, It must be distinguished between two types of problems concerning neighboring foundations:
The study of interaction between a foundation and another neighboring foundation or an external load has been considered by several authors. Mikhaiel(1978) presented an application on the use of the elastic half space model in the determination of the effect of neighboring loads on the existing building.Selvadurai (1983) examined the interaction between a rigid circular foundation and an external load. The additional settlement due to neighboring foundation, external loads and buried structures can be considered as follows indicated in the next paragraphs.
Description of the problem:
Besides the possibility of studying the influence of neighboring structures on the foundation by the program ELPLA, the described algorithm of ELPLA can be used also for the calculation of settlements outside the foundation. This can be carried out through one of the following two ways:
