Dear Sumit,

1st, you have to calculate the reduced bearing capacity due to the existing slope, you may use the attached pages from Bowles handbook

2nd, after design the footings it is strongly recommended to check the general stability of the slope using any free available slope stability software specially for clayey soil or multi-layered soil.

3rd, For pure granular soil, you may neglect the general slope stability if you applied the IBC recommendation (slope = 18 degree) between adjacent footings, because the safety factor for pure granular soil = tan (Fi) /tan (slope) , hence, for well compacted medium sand, Fi = 35 degree, then the safety factor = tan(35)/tan(18) = 2.15

4th, To use empirical slope 1V:2H as shown in your figure, you must have a dense granular soil (Fi > 40 degree ) with light bearing capacity and it is recommended to check the slope stability

I hope this helps you

regards

Dear sir Witold,

Thank you so much for your reply to my query. I've understood what you meant. KEYWORDS: Slope stability analysis, Foundation interaction. Now onward, I'll incorporate & present your suggestion during my presentation.

Dear sir Ahmed,

Your advice & attachment are highly acknowledged. You've given such an explicit explanation. I'll go thru the attached file & move my work ahead with your valuable suggestion. Thanks many!!
