INTRODUCTION

1.0       General Introduction

When a structure such as building or dam is constructed over the ground, its load has to be transferred to the underlying soil in such a manner that no damage occurs to the structure due to failure of the foundation soil.

There are two factors that needs to be considered when designing the foundation of a structure for safe distribution of load on the soil below the structure:

1. The load applied to the soil should be such that the induced stress in the soil is lesser than the bearing capacity of the soil ,as otherwise, soil will fail by shear, and
2. The settlement in the soil should be such that it is within the tolerance limit of the super-structure.

The safe bearing capacity or the allowable bearing capacity (q_a), is thus, defined as the maximum pressure which may be applied to the soil, such that the above two fundamental requirements are satisfied. The foundation should, therefore, be designed , so that the allowable bearing capacity of the soil is not exceeded, hence the foundation will failed by shear. The shear failure and shear strength of the foundation soil gave rise to this piece of work “Estimation Of The Bearing Capacity Of Soils At Some Sites Around Uyo Metropolis, Using Shear Box Data Method“.

A geotechnical investigation of a site which includes estimation or determination of the bearing capacity of the soil is a process of collecting information, and evaluation of the site for the purpose of designing and constructing the foundation for the structure. Therefore a geotechnical engineer is call upon to predict the behavior and the performance of the soil as a construction material or as a support for engineering work. The geotechnical investigation process includes;

• Excavation of trial pits
• Soil sampling (both disturbed and undisturbed).
• Determination of 1, Natural moisture content, 2, Atterberg limit 3,soil grading 4, shear box data  5, Bulk density  6, Specific gravity of the soil.

 

1.1       Site Description

The project is aiming at investigating a three site in Uyo metropolis, the capital of Akwa Ibom State, Nigeria. The site are :

1. New Stadium road, Obio Offot Uyo, accessed through Uyo- Abak road, with the co-ordinates5^o00’49”N,7^o53’07”E

1.3       Problem Statement

Defining subsurface conditions that influence the sitting, design and performance of a project to identify underground features and conditions, characterizing their physical properties and delineating their vertical and lateral extent.

 

1.4       Scope and Objectives of Study

Geotechnical properties of soil such as its grain size distribution, plasticity, compressibility and  shear strength are assessed by proper laboratory test while emphasis is placed on the in-situ determination of strength deformation of soil properties because the process avoids disturbing samples during field exploration. The ultimate aim of estimating bearing capacity of soil is to assess enough information to select the most appropriate foundation solution to outline problems that could arise during construction and on a more general scale, to highlight potential geological hazards in the examined area as well as to:

• Determine the location and variation in the ground water table checking whether it is in the zone of design interest or not.
• Evaluate the load bearing capacity of the soil.
• Determine location of bedrock.
• Determine and design the type and depth of foundation for a given structure.

1.5       Expected Output

The investigation provides data on surface and underground conditions at the proposed site and samples may be obtained for visual inspection and to determine physical and index properties.
