The bearing capacity of shallow foundation near slope has always been one of the subjects of major interest in geotechnical engineering for researchers and practical engineers Bearing capacity is the power of foundation soil to hold the forces from the superstructure without undergoing shear failure or excessive settlement. Foundation soil is that portion of ground which is subjected to additional stresses when foundation and superstructure are constructed on the ground ** BEARING CAPACITY OF SHALLOW FOUNDATIONS 3**.1 MODES OF FAILURE Failure is defined as mobilizing the full value of soil shear strength accompanied with excessive settlements. For shallow foundations it depends on soil type, particularly its compressibility, and type of loading It is usual to assume an increase in bearing capacity when the depth (D) of a foundation is greater than the breadth (B). The general bearing capacity equation can be modified by the inclusion of depth factors. q f = c.N c.d c + q o.N q.d q + 1/2 g.B.N g.d g. The chart on the right shows Skempton's bearing capacity factor, N cu, for undrained.

A more rigorous methodology is that of limit analysis, which provides both lower and upper bound assessments The problem of static bearing capacity of shallow foundations has been extensively studied in the past by Terzaghi (1943), Meyerhoff (1963), Vesic (1973) and many others.

Geogrid under Foundation in Plaxis 2D (Bearing Capacity) The use of geosynthetic materials to improve the bearing capacity and settlement performance of shallow foundation has gained attention in the field of geotechnical engineering. For the last three decades, several studies have been conducted based on the laboratory model.

Following the popularity of the previous edition, Shallow Foundations: Bearing Capacity and Settlement, Third Edition, covers all the latest developments and approaches to shallow foundation engineering. In response to the high demand, it provides updated data and revised theories on the ultimate and allowable bearing capacities of shallow. Meyerhof's Bearing Capacity theory. In 1951, Meyerhof published a bearing capacity theory which could be applied to rough shallow and deep foundations. Meyerhof (1951, 1963) proposed a bearing-capacity equation similar to that of Terzaghi's but included a shape factor s-q with the depth term Nq The value of is calculated by using the formula for the bearing capacity of foundation proposed by Terzaghi : where , and are the cohesion, internal friction angle, soil unit weight of footing embedment, and unit weight of the soil beneath the footing, respectively; and and are the foundation bearing capacity factors

The bearing capacity of the soil is a significant topic in geotechnical engineering, especially in foundation engineering, as the stability of any foundation depends on it. A structure with a very sound design may collapse standing on poor soil with low bearing capacity. As the depth of the water table increases, the ultimate bearing capacity of soil increases Types of Shallow Foundation. Shallow foundations are subdivided into a number of types according to their size, shape, and general configuration. They are described below. 1. Spread Footing. This type of shallow foundation is the most common of all types of footings involving minimum cost and complexity of construction (##Fig. 15.1a) shallow foundation using the probabilistic approaches by assessing certain level of reliability, identified numerically by reliability index or probabilistic failure [4-10]. This study aims to investigate the impact of variations in soil properties on the ultimate bearing capacity of a square shallow foundation. The tw Shallow foundations need enough area to transfer the heavy loads to the base soil. As mentioned above, we chose shallow foundations when the soil has adequate Soil bearing capacity. Footings in Shallow foundations may be of Masonry, Plain concrete or reinforced concrete. The depth of shallow foundations are generally less than its width Vertical bearing capacity factors for the surface and embedded circular foundations predicted from the FEA were compared with exact solutions for the surface foundations (Martin, 2003) and upper bound solutions for the embedded cases (Martin & Randolph, 2001).
