Parametric Studies on Application of CPRF on Semi Soft Stratified Soils
In the last four decades Combined Pile-Raft Foundations (CPRF) have been successfully applied in different parts of the world for optimizing foundations of civil engineering structures. This paper is an extension of the research works being carried out to widespread the concept further. A number of three-dimensional non linear finite element analyses on four-layered subsoil conditions of the West-African city Lagos have been carried out. Evaluation of the dominant parameters of CPRF, i.e., the settlements and pile-raft coefficient, have shown that the economical use of this system is dependent on the level of the applied load, configurations and length of piles as well as stiffness of the different soil layers. The parametric study shows that the application of CPRF is appropriate on semi-soft multi layered soils if the right combination of loading, material and geometric configurations is used. Some recommendations are given for such combinations of input parameters, enhancing the behavior of CPRF on semi-soft multi-layered soil conditions.
