In the case of problematic soils and tall buildings where the design requirements cannot be satisfied merely by a raft foundation, it is of common practice to improve the raft performance by adding a number of piles so that the ultimate load capacity and settlement behavior can be enhanced. In this study, the effect of spatial variability of soil parameters on the bearing capacity of piled raft...

The undrained shear strength is a paramount parameter in determining the consistency and ultimate bearing capacity of clay layer. This resistance can be determined by in-situ tests, such as field vane test or laboratory including portable test, triaxial, simple compression penetrometer (i.e. Swedish cone). However, cone are most commonly used geotechnical experts. In this paper, relationships b...

Abstract As population grows, more land areas are used up for accommodation, industrial needs as well infrastructure. This results in diminishing availability of soil with good characteristics that can be used. limitation forced future construction to built on soils poor characteristics. These types require improvement order make them viable construction. A relatively new and sustainable method...

recently, mixtures of clay-tire chips are used as construction material in civil engineering projects. with respect to the tending for using these materials, it is necessary to know their mechanical behavior. thereby, a number of undrained monotonic triaxial tests are carried out on the specimens of pure clay and clay-tire chip mixtures. mixed specimens prepared by mixing pure clay with 10%, 20...
