How do you calculate slope of excavation?

Slope Angle Calculations



This simple equation will tell you the proper opening width: (depth x 2) x type slope ratio + width of original excavation = top width. As an example, let’s calculate the slope angle of a simple trench that is 6 feet deep by 2 feet wide, factoring in the type of soil. Type A: (6 feet x 2) x .

What is the average depth of excavation cave in?

What is Prismoidal formula?

1) Prismoidal Formula:



This formula is based on the assumption that A1 and A2 are the areas at the ends and Am is the area of mid section parallel to ends, L=Length between the ends. From mensuration, volume of a prism having end faces is in parallel planes: V=L/6*(A1+A2+4Am) This is known as prismoidal formula.
