Reliability Analysis of Settlement of a Foundation Resting Over a Circular Void
https://orcid.org/http://orcid.org/0000-0003-0622-6978
The presence of any type of excavation or void underneath the foundation of a structure is one of the factors that affect the stability and may cause extreme damage to the structure. The factors affecting the bearing capacity and settlement of foundation are soil properties, operational conditions, void size, location of the void, number of voids and depth of foundation. Any subsurface development will create ground vibrations that subsequent in-ground settlements and lateral movements, which can make harm the current surface and underground structures. Thus, the existence of underground cavities for significant and immense structures, such as pipelines and tunnels, affects its serviceability. Finite Element Method (FEM) has gained popularity in the field of subway development using computing technology for the analysis of surface settlement. This paper shows an analysis of the effect of excavation below the shallow foundation on its stability and a reliability approach to study the same. Finite Element Analysis package PLAXIS 2D is used for the analysis of the performance of footing over a void under different boundary conditions. A model is prepared and the analysis was done by varying the depth of void within the pressure bulb of a strip foundation, the eccentricity of the void from the centre of the foundation and the load of the superstructure. The result of the varying depth of the void, the position of void in the horizontal axis and the load of the building on the ground surface settlement is shown in terms of the Gaussian distribution curve. The settlement data are further used to carry out the reliability assessment to check the dependability of the study.
