SOLVE To determine the capillary head and the permeability of a soil, a tube containing a soil with a void ratio of 0.6 was kept horizontally in a trough filled with water with its centre at a depth of 7.5 cm from the water level. Water was found to advance from 1.5 cm to 12 cm in 8.5 minutes. In another test with the same soil kept at a depth of 22.5 cm below water level, water was found to advance from 13 cm to 21 cm in 10 minutes. Determine the capillary head and the coefficient of permeability of the soil. Take saturation S = 100% for soil sample.

A layer of sand 6 m thick lies beneath a clay stratum 5 m thick and above abed thick shale. In order to determine the permeability of sand, a well was driven to the top of the shale and water pumped out at a rate of 0.01m3/sec.

A vane shear test was performed on a clay layer using a vane with a diameter of 75.8 mm and a height of 151.6 mm. The vane was inserted to the total length of the vane (151.6 mm) but the top edge was exposed. The maximum moment required to rotate the vane was measured as 145 N·m. The liquid and plastic limits of the soil were 48 and 21, respectively. Determine the design undrained shear strength of the clay.

Before the construction of a raft foundation for a large reservoir, piezometers were placed in the saturated clay layer. The whole process of filling the reservoir may be approximated to applying rapidly a single pressure increment of 200 kPa uniformly throughout the clay layer. One year after filling the reservoir, the piezometers indicated a distribution of excess porewater pressure as indicated in Figure Q-e. Estimate the average degree of consolidation at this time.

Soil borings made at a site indicate that the top 8 m is a loose sand, with the groundwater table at 4 m below the ground surface. Below this is a fairly soft blue-gray silty clay with an average water content of 30%. The boring was terminated at 20 m below the ground surface when fairly stiff silty clay was encountered. For the upper sand gammadry = 14.0 kN/m3 and gammasat = 15.0 kN/m3 , where gamma is the unit weight. For the clay, ps = 2.70 Mg/m3 where p is density.
