Hart Crowser J-3446-01 ► Anticipate about 1 inch of total settlement and '/�-uuh differential settlement of a slab with a sustained loading of 125 ps£ The slab- induced setclement will be shart term. ► Any so�7 that is to be considered as capillary break material should be submitted for fines content analysis. Retaining T�'all Design Figure Z shows truck loading and tuiloading on the south side of the warehousc. This section on ret..i:iing wall design is applicable if truck wells are used in this ar�a. Structural Design. For retaining walls bac;�lled on one side only, thc structural engneer can estimate the latera] ioad and resistance on the wa11s using an equivalent fluid to represent the soi7. We make the following recommendations for walls with compacted backfill placed above the water table: ► For a yielding wall (active horizontal so� pressure coef6cient) w�th lcvel backfill, the equivalent fluid weight of the so�7 is 35 pc£ We define the yieiding wall as one where the top moves, when loaded, at le:ut 0.1 percent of iu heigh� ► For a non-yielding wall (at-rest horizontal soIl pressure coefficient) with ]evel back�fill, the equivalent fluid weight is 55 pc£ Note that the equivalent fluid weieht does not consider any surface loading condidons. Estimate the ]ateral loads resulting from surface area surcharges as 35 percent of the surface load for a yielding wall and 50 percent for a non-yieiding wall. Drainuge Design. Place 13 inches of well-graded sand and gravel w�th less than 3 percent fines behind all retaining walls and subgrade walls. Pavement Design . We mal:e the following recommendations concerning pavement design: ► Use a CBR value of 15 percent for design of pavement sections; Pag� 1
