OSH 379 Soil Safety / Trenching Safety Quiz Week 5 1. Define “trench.” a. A narrow excavation (in relation to its length) made below the surface of the ground. In general‚ the depth is greater than the width‚ but the width of a trench (measured at the bottom) is not greater than 15 feet (4.6 m). If forms or other structures are installed or constructed in an excavation so as to reduce the dimension measured from the forms or structure to the side of the excavation to 15 feet (4.6 m) or less

So by the constraints 1 < Cc < 3‚ we can conclude that the testing soil is not well-graded‚ but poorly graded. And the Cu obtained is 7.0513 > 6‚ which implies that the sample should be sand but not
