Filling Path

For computing the stress and strain of embankment dams, FEM is employed. Two reservoir filling paths which are constructing filling and completed filling are considered to affect the computing results. It is proved that constructing filling path can enhance the stress of embankment dams. So constructing filling path can take from the hydraulic fracturing of core wall. In addition, constructing filling path can decrease the amount of settlement, and can control the displacement of dam shoulders. In a word, constructing filling path is prior to completed filling path.

AbstractVery low frequency (VLF) was used to assess variations in overburden composition, bedrock lithology and the concealed basement structures within the bedrock of Owena Dam in Igbara-Oke of the Precambrian Basement Complex of Southwestern Nigeria. Five VLF-electromagnetic (EM) traverses were occupied at 5 m intervals. The VLF normal and filtered real component anomalies identify major geological interfaces suspected to be faults/fractured zones. The points of crossover between the real and imaginary components delineate the fractured zones, which were identified as areas of possible seepage (piping and sloughing). The internal erosion (permeability) of soil mass eventually leads to the formation of an open conduit in the soil, which may lead to failure of the embankment/dam. The fractured zones are suspected to be present at all traverses. In total, 21 fractured zones were identified along the dam embankment, with the deepest occurrence at Traverse 5. These seepage zones cause heterogeneity in the subsurface composition, which could lead to dam failure. The result of the study suggests that VLF is an adequate method of monitoring seepages in embankment dams.
