Liquefaction Resistance of Coarse-Grained Alluvium at Calero Dam
Calero Dam is a 30 m-high embankment dam located in a seismically active area, about 21 km southeast of San Jose, California. The dam straddles a flat and wide stream valley blanketed by 4.5 to 6 m of alluvium overlying bedrock. The alluvium was excavated beneath the embankment upstream shell but was left in place beneath the downstream shell. The lower 1.5 to 3 m of the alluvium consists of sandy gravel and gravelly sand, whereas the upper 1.5 to 3 m is mostly fine-grained soil of medium plasticity. The liquefaction resistance of the coarse-grained alluvium (CGA) was investigated with standard penetration test borings, Becker penetration test soundings, and shear wave velocity (Vs) measurements. This paper describes the field investigations and analyses of liquefaction potential. The effects of the embankment on the penetration resistance of the CGA and its liquefaction resistance are discussed.
