Web16 Dec 2024 · However, the compaction stage of the rock stress–strain curve is rarely considered when establishing rock damage constitutive relations, which involve the mechanism of initial crack closure, and is important for analyzing the initiation, growth, and aggregation of new cracks during the deformation of brittle rocks. 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 …
