Abstract EN
This paper reports the application of using a skirted foundation system to study the behavior of foundations with structural skirts adjacent to a sand slope and subjected to earthquake loading.
The effect of the adopted skirts to safeguard foundation and slope from collapse is studied.
The skirts effect on controlling horizontal soil movement and decreasing pore water pressure beneath foundations and beside the slopes during earthquake is investigated.
This technique is investigated numerically using finite element analysis.
A four story reinforced concrete building that rests on a raft foundation is idealized as a two-dimensional model with and without skirts.
A two dimensional plain strain program PLAXIS, (dynamic version) is adopted.
A series of models for the problem under investigation were run under different skirt depths and lactation from the slope crest.
The effect of subgrade relative density and skirts thickness is also discussed.
Nodal displacement and element strains were analyzed for the foundation with and without skirts and at different studied parameters.
The research results showed a great effectiveness in increasing the overall stability of the slope and foundation.
The confined soil footing system by such skirts reduced the foundation acceleration therefore it can be tended to damping element and relieved the transmitted disturbance to the adjacent slope.
This technique can be considered as a good method to control the slope deformation and decrease the slope acceleration during earthquakes.
