CRACKING, LEAKAGE, AND EROSION OF EARTH DAM MATERIALS

A laboratory approach is brought out to investigate the cracking, leakage, and erosion properties of the soils used in dam cores, and an apparatus is developed for the purpose. The applicability of the approach has been demonstrated by carrying out experiments on two Norwegian soils: (1) A well-graded material with no clay size particles and; (2) a silty-clayey fine sand. It is seen from these tests that the two soils have quite different cracking, leakage, and erosion properties under tensile deformation. The graded material shows self-healing attempts but the silty-clayey fine sand behaves in a way similar to the piping phenomenon. (ASCE)
