![=
7.1 A foundation for a long concrete block wall of thickness
0.2 m (8 in.) will be founded on a dense sand ( from direct
shear test = 32°; D, 85% and Ysat
17.8 kN/m³3 (113 pcf)).
The wall will transmit a vertical live load load of 60 kN/m
(4000 lb/ft) in addition to the estimated foundation dead load of
7.5 kN/m (500 lb/ft). The foundation is to be located 0.5 m
(1.5 ft) below finished grade. The groundwater level is
5 m (16 ft) below finished grade. Determine the size of
the foundation (width) using ASD for FS-3.) Investigate
the effects of a rise of the groundwater to (a) the ground
surface and (b) the foundation base.
