An Earth Fill Dam on Permafrost: Hess Creek Dam, Livengood, Alaska.

The Hess Creek Dam is a combination hydraulic fill and rolled earth fill structure containing about 479,000 cu yd of earth fill. A steel sheet pile cutoff wall runs along the base centerline. A 48-in.-diam metal pipe outlet with control gate was installed through the embankment at one end and a spil...

Description
Summary:The Hess Creek Dam is a combination hydraulic fill and rolled earth fill structure containing about 479,000 cu yd of earth fill. A steel sheet pile cutoff wall runs along the base centerline. A 48-in.-diam metal pipe outlet with control gate was installed through the embankment at one end and a spillway 1300 ft long and 100 ft wide was built to accommodate flood flow. The performance and present condition of the dam suggest that construction of earth fill embankments on permafrost is feasible and practical. The embankment appears to have had little or no detrimental effect on the underlying permafrost. The refrigeration system installed at the base of the embankment seems to have accomplished its purpose of refreezing foundation soil thawed during the summer construction period. (Author)
