How to determine the Critical Depth in Open Excavation? [PDF]

WebWhen excavated, the material breaks up into different size particles that do not fit together, creating voids that reduce the weight per volume. For example, to hold the same weight of one cubic meter/yard of material, it takes 30 percent more volume (1.3 times) after excavation if the swell is 30 percent. Load Factor: The ratio of the loose ... WebAn open excavation performed beyond the critical depth of the given soil type, results in the dissipation of residual stress, aiding to the instability of the soil mass. Critical depth is a … WebRock strength: stronger rocks have a greater bulking factor than weaker ones, where the rock is likely to break during excavation and so producing a greater variation in particle size distribution, producing a lower bulking factor.

WebWhat is compaction? Soil compaction occurs when soil particles are pressed together, reducing pore space between them (Figure 1). Heavily compacted soils contain few large pores, less total pore volume and, consequently, a greater density. A compacted soil has a reduced rate of both water infiltration and drainage. This happens because large pores … Webexisting embankment . Any slope excavated into existing fill, alluvium, colluvium, residual soils, or weak sedimentary formation is considered a soil cut slope. Slopes excavated into highly fractured and weathered rock may also be considered soil cut slopes. Soil cut slopes may be preferred over other roadway prism widening alternatives such as

WebShrinkage = volume after compaction/volume before excavation. Both the loose and compacted volume are calculated from the bank volume. Example: If you are excavating dry clay it is listed as having a swell of 50% and a shrinkage of -10%. That means that for every 1 cubic metre/yard of material that you excavate the volume increases by 50%. WebStep 1. Calculate the volume of the space to be filled. For example, find the cubic footage volume of a backfill area that is 8 feet wide, 6 feet deep and 50 feet long. The volume of a rectangular cubed shape is found by the formula v = l x w x d, where v represents volume, l is the length of the trench, w is the width and d is the depth.
