Ap . <br /> awer I�ei �ar� <br /> �y we;�* � <br /> PM <br /> Allan Block retaining walls c�n be reinforced with the same proven techniques pPP���ations <br /> used for conventional masonry walls. Allan Block masonry walls are useful on sites <br /> where geogrids are not feasible or cost effective because lhey rely on a reinforced <br /> footing and vertical pilasters to counteract laleral earth preswres. These walls :;. <br /> combine the mortarless stability of an Allan Block wall with the tensile strength of � H�9� � <br /> the steel rods in pilasters, and Ihe stability of the fooling. The design antl <br /> construclion of these walls follow lhe guidelines outlined in current ACI standard ��� <br /> and ezisting UBC design crileria, while � <br /> lacroring in the benefit of an inclined Typital Seetion �'.w <br /> Atlan Block wall. The specific design • �� � <br /> requirements depend on sile and soil ,,,,,, �^-°-�^ t,s� <br /> condilions, and wall heights. �__m �� � <br /> See�eference 75 .�,. - --•••--�- <br /> ...<... • W. <br /> -� ,..,._..... �r-i <br /> .� <br /> " - ` " ..�., • Goif' <br /> Q <br /> '\L �....�.. <br /> - � � -=_._._,.�...., • Tem <br /> �_,�- ,, �- - �,� <br /> �� x � ..�..... �'—• ;,_ -��� ,�_ <br /> k-- • -- <br /> �z� � � <br /> �„ ;•. <br /> . . , �� <br /> ��� . .
