Movement within Large Fills on the San Luis Reservoir Relocation Project
In years past the design and construction of highway embankments in California were based largely on considerations of foundation soil conditions. For the most part the largest fills did not exceed much over 100 feet in height. In more recent times, with the increasing tendency towards designing and constructing embankments from 200 to 400 feet high, there has been cause for concern regarding the structural integrity of the fill itself. On several occasions considerable subsidence of the roadway surface and some bulging of the side slopes has been observed in moderately high fills, where foundation conditions were apparently sound and firm. This has led to conjecture that compression and horizontal movement or so called 'fill dialation' was occurring in these instances. It is considered highly probable that the stresses resulting from high fill loadings could actually exceed the strength of some soils used in embankments under certain circumstances. Various theoretical approaches have been made to the problem but a very serious need is felt for data relating actual compression and movement encountered in high fills.
