" ,.�:�. <br /> r���: <br /> Because of the slope of the site, tne fill area should be Denche6. While �:s <br /> -' the site 9lacial till soils may be used for the comqacted till, these soils <br /> must be compacted at ornear optimum moisture cantent. It censtruction is f <br /> — =� <br /> done 1n late fall or early spring, it may be Citficult to place these so11s w= <br /> �r; <br /> _ at the proper moisture content so that it may be necessary ta use a granular <br /> � till. At least 6" of free-draining granular soil should be provided <br /> "' immediately below the floor slab. ,�; <br /> A portion of the lower level will be below the 9round surtace. T�e nasement ' <br /> , walls Sn this area will be subjected to lateral loads. Since the top af <br /> - ��. <br /> � � these walis will be restrained, the walls should De designed based dn an f� ti�' � <br /> ,� r�,+� <br /> f�7'�: <br /> � nt-rest soil pressure. For the natural soils at this site, we recomnenC 'A <br /> ' using a IC� of 0.15 and a weight for the soil of 130 pcf. A minimum of Z' of <br /> h- <br /> ,> <br /> free-draining granular soil should be provided adjacent to the walls for <br /> Qrainage. The upper 1' or so of fiil can be an impervious clay to �inimize <br /> � . surface infiltrat�on. Although there is no evidence of ground water in t�e <br /> -• borin9s� we suggest providing a perimeter draln tile system for that portion <br /> `" of the lower floor buried bela+ grade. <br /> ,y. <br /> The pressure on the walls can be reduced by increasirtg the area of clean <br /> ,,, granular backfill. By increasing the area of backfill to include an area <br /> . beginning 1' out from the wall and upwards and outwards at an angle of 30°. <br /> " the walis could be designed for an equivalent fluid weight of 45 pcf. Again <br /> A a layer of clay can be provided at the surface to minimize surface <br /> � <br /> infiltration. <br /> � <br /> r <br /> � � k <br /> � l <br /> �" , Aq �'�: �, x„' s � <br /> #,_ .. 7°v''�4,�}`^'�1r� k�( }� 'f:,�`?��� �t � �2 f�'� �` a�`�r^ 3``Y„�^9a-�' aj +�"zt�' w .���"�lL� . �"t 1. �. �t <br /> ,,� ,,.
