fifty-foot-high approach embankments recently completed for a bridge crossing of rainier avenue in downtown seattle required preloading of compressible lacustrine clay sediments as much as 50 ft thick below the abutment areas. this paper presents the results of engineering analyses and recommendations for very complex surcharge fill requirements. vertical prefabricated drains were used in the preload to accelerate settlement and an unprecedented 55-ft-high soil-reinforced wall was used to limit the extent of the fill and thereby prevent damage to existing utilities and adjacent structures the instrumentation program used to measure the settlement response is discussed, and the variation in magnitude and time rate of settlement measured across the site is summarized.
