Abstract:
Soil that alters with the variation in environmental situations when used for constructional activities is usually present. For ages, construction on such ground has been a pronounced challenge in the arena of geotechnical engineering, as it results in the slow progress of work due to instability of the ground and cost overruns in the accomplishment of the project. The major geotechnical issues associated with such types of soils include slope instability, excessive settlement, bearing capacity failure, etc. Such soil shows common challenges for the sustainable and serviceable design and further construction of structural foundations. Thus, the study of pile-raft foundations is of utmost importance to use such soils. Hence, the current paper contains a study made on pile-raft foundation on cohesionless soil with the help of PLAXIS 3D, which is a 3D Finite Element Method (FEM) / programme which is used for distortion as well as stability analysis of numerous geotechnical applications. The analysis involves the effect of internal friction angle (ф) in the settlement study of cohesionless soil. The current study also noted that the dilatancy angle can impact the load settlement of cohesionless soil. It was observed from the current effort that with an increase in the angle of internal friction angle, the settlement was noted to decrease gradually. Thus, the study of cohesionless soil should be conducted in depth to comprehend the effects of other vital parameters.
