sz v Ip (0.47)(50 kPa) 23 kPa
The stress increase of 23 kPa is only applicable at the top of the clay layer. However, using this
value for the center of the clay layer and since OCR 1, from Eq. 8.12:
sc Cc [Ho (1 eo )] log [(s′vo v)s′vo]
sc (0.83)[(2 m)(1 1.1)] log [(150 kPa 23 kPa)150 kPa] 0.049 m 4.9 cm
