30 Jun 1995 This report presents the results of a research project undertaken to provide a comprehensive state-of-the-art review of the procedures used by the geotechnical engineering profession to estimate the settlement of shallow foundations resting on granular soil deposits. A comprehensive review was made of

5-1 THE SETTLEMENT PROBLEM. Foundation settlements must be estimated with great care for buildings, bridges, towers, power plants, and similar high-cost structures. For structures such as fills, earth dams, levees, braced sheeting, and retaining walls a greater margin of error in the settlements can usually be tolerated.

The overturning moment causes eccentricity in the loading configuration that effects the resultant load and the pressure distribution that develops along the base of the footing.

SETTLEMENT OF FOUNDATIONS. 7.1 INTRODUCTION. Settlement can be defined as the permanent downward displacement of the foundation. There are two basic types of settlement: 1. Settlement due directly to the weight of the structure. The first type of settlement is directly caused by the weight of the structure.

These foundations types are illustrated in Fig. 13.1. The most common type of foundation is the footing which consists of an enlargement of the base of a column or wall so that the pressure transmitted to the foundation material will not cause failure or excessive settlement. In order to reduce the bearing pressure transmitted

For example, in a consolidation settlement problem, stress increase, ??z, values are needed to calculate settlement under a foundation loading. We make the following calculations for a point located under the foundation at a certain depth (for example, at the mid-depth of the compressible layer):. (1) First, calculate the initial
