“…Compared with the results by Chen 28 , Saran et al 32 , Yamamoto 47 , and Yang et al 38 , the proposed method can provide smaller values of the upper bound solution in most cases. Also, the proposed results are close to those by Meyerhof 1 and Mizuno et al 48 involved in limit equilibrium method. It should be noted that compared with the method of optimizing the velocity field in deformation mechanism by Yang et al 38 , the proposed results are always even smaller upper bound solutions.…”

In terms of five bilateral failure modes of shallow rigid strip foundations near slopes, kinematically admissible velocity fields are constructed using a generalized log-spiral shear mechanism improving the traditional failure mechanism by introducing a geometric factor. The upper-bound solution of the bearing capacity for the foundations near slopes is accordingly derived. The minimum of the five values is the required solution, and the corresponding failure mode is the accepted one. Some examples show the proposed results are fairly close to those by other theoretical and numerical methods or laboratory model tests, and in most cases the geometric parameter of the generalized mechanism is between 0.7 and 1, which means the failure mechanisms of the systems are considerably optimized. The influence of slope height, foundation depth and width, distance from the foundation to slope crest, and soil properties on the transformation among these failure modes is provided. Analysis results of many examples show that there is not rigorously linear relationship between the bearing capacity of foundations near slopes and cohesion or depth of the footing. Besides, a table of comprehensive factor expressed to reflect the slope effect on the bearing capacity for convenient applications.

“…The presence of a sloped ground near to a footing may cause a major decrease in the bearing capacity of footings, as shown analytically by Mizuno (1960), Meyerhof (1963) and Kusakabe et al (1981). Seismic forces account for another major bearing capacity decrease for footings, as analytically shown by Sarma and Issifelis (1990), Richards et al (1993), Tatsuoka et al (1998), .…”

“…(Sokolovsky [3] ,1960;Reddy and Mogaliah [4] , 1975) solved this problem by using slip line approach. Limit equilibrium analysis was used by Mizuno et al [5] . 1960; Reddy and Mogaliah [6] , (1976); Bowels [7] , (1977) and Myslives and Kysela [8] , (1978) to solve the problem of foundations near slopes.…”

In this study, the behaviour of shallow foundations near slopes is studied using nonlinear elastic finite element analysis. Forty-four cases of strip footings resting on cohesionless soils that were studied by Sud (1984)[1] through model tests, have been analyzed. Pressure-settlement relations has been compared with experimental results of (Sud, 1984) [1], and a good agreement between the two has been observed. Ultimate bearing capacity of shallow foundations near slopes was evaluated using the intersection of two tangents of pressure-settlement curve. The values of ultimate bearing capacity agree well also with (Sud, 1984) [1]. A non-dimensional correlation has been developed between the settlement of footing erected near slope (Sβ) and the settlement of footing resting on level ground (So). The relationship (Sβ/So versus De/B) can be expressed by a unique relation for different slope angles (β). This relation has been found to be dependent on distance of the edge of the footing from slope shoulder; De, and angle of slope; β, while it is independent of the relative density of sand; DR, and the factor of safety. By knowing the settlement of a footing resting on a level ground, the settlement of a footing erected near slope can be evaluated using this correlation.
