Using of Stones in Building the Foundations

Abstract

The problem of this study is that the building of foundation by stones at the present time leads to develop cracks in the superstructure. Therefore, the solutions and the right manner were suggested for building the stone in the small and big structures. This paper studies using and properties of stones in building of foundations, that the stone is rigid and stiff in the same time very cheap for building, especially in the regions wealthy with stone. The models were taken for analyzing, firstly experimentally in the field site and secondly by Plaxis Program using the Finite Elements with the same properties of the soil and calculate the vertical displacement, vertical strain, factor of safety and bearing capacity. It can be concluded that the using of the reinforced columns in the small foundation in addition to the beam and stones will reduce the vertical displacement and strain to lower values, maintain high value of bearing capacity and increase the factor of safety that makes the structure becomes safer. Also for the big structures like bridges another models were used with higher loadings and the same above parameters were calculated, the stone with special requirements approved to improve and treat the soil parameters even for the big structures.
