For a triaxial compression test under untrained condition, the deviator stress and the pore water pressure at the failure were recorded as 75kPa and 45kPa respectively. Calculate the internal friction angle if the test was performed at a confining pressure of 110KP..Part A The data below shows the laboratory data for a fluid obtained using a viscometer at 20°C and 1 atm. -du/dy (sʻ1) T (Pa) 25 62.3 50 81.9 100 106.4 a) stress and shear rate.

- The tube is subjected to a torque of 749 N-m Figure 62°5 6 mm 100 mm 4 mm 4 mm 60 mm B 6 mm 1 of 114.30 (B). A certain equiangular strain gauge rosette is made up of three separate gauges. After it has been installed it is found that one of the gauges has, in error, been taken from an odd batch; its gauge factor is 2.0, that of the other two being 2.2. As the three gauges appear identical it is impossible to say which is the rogue and it is decided to proceed with the test. The following strain readings are obtained using a gauge factor setting on the strain gauge equipment of 2.2: Gauge direction Strain x 10-6 0° 60° 120° +1 -250 + 200 Taking into account the various gauge factor values evaluate the greatest possible shear stress value these readings can represent. For the specimen material E = 207 GN/m2 and v = 0.3. [City U.] [44 MN/m2.]Assuming that the shear area remains constant during the test, determine the effective cohesion and effective friction angle from these test results. What values of these parameters would you expect? Are the test results consistent with your expectations? What values would you use for design?
- sand deposit has been identified beneath a site located adjacent to a river. The sand deposit is 15 feet thick and the top of the layer is 12 feet below the ground surface and overlain by a very stiff clay and is underlain by bedrock. The water level has been measured to be at a depth of 10 feet. The standard penetration resistance of the layer has been determined to be 12 blows per foot and a standard sampler was used; a drill rig with a safety hammer with an efficiency of 60% was used. The length of the drill rod is 10 meters and the borehole diameter is 5 inches (127 mm). The design earthquake has been designated as a moment magnitude 6-3/4 event on a nearby fault and the maximum ground acceleration is expected to be 0.40 g. The wet unit weight of the clay soils is 150 pounds per cubic foot and the wet unit weight of the sand soils is 180 pounds per cubic foot. The sands have 35% fines content according to a grain size analysis. Compute the factor of safety against liquefaction of…Mohr’s Circle ; Direct shear test was performed on dry, sandy soil.
