An exploratory drill hole was made in a stiff saturated clay having a moisture content of 38.9% and Gs = 2.34 as shown in the figure. The sand layer underlying the clay was observed to be under artesian pressure. Water in the drill hole rose to a height of 13.8 ft above the top of sand layer. If an open excavation is to be made in the clay, determine the (a) unit weight of the clay, and the (b) maximum cut before the bottom heaves.
A concrete culvert is to be constructed in a bed of sand (e = 0.65) for drainage purposes. The crown of the culvert will be located 3.5 m below ground surface. Currently, the groundwater level is at ground surface. But, after installation of the culvert, the groundwater level is expected to drop to 2 m below ground surface. Calculate the change in effective stress on the roof of the culvert after installation. You can assume the sand above the groundwater level is saturated.
