CTR11534/CTR11134Geotechnical Earthquake and Offshore EngineeringCoursework submission 2 (50% of module marks)Submission deadline: May 14th, 2021 by 16:00 (UK time)1. A mass gravity wall with the geometry shown in Fig. Q1 is retaining a soilof γ = 20 kN/m3, φ’ = 35o and a slope 10o. Using the Mononobe-Okabemethod, determine the PA, PAE, ΔPAE and overturning moment at the base.Fig. Q1. Gravity retaining wall(8 marks)2. a) Assuming kh = 0.1 and kv = 0.0, compute the pseudo-static factor ofsafety for a slope with height H = 10 m and slope gradient 2:1 (H:V). Theslope faces to the left (i.e. highest part of the slope is on the right). Forconceptual design purposes, assume a slip circle with centre located 21 mabove and 18 m to the right from the toe of the slope, respectively. Soilproperties are cu = 100 kPa and  = 18 kN/m3(8 marks)b) Comment on whether this is likely to be most critical slip circle and whatwould you do to estimate the most critical factor of safety.(3 marks)c) How would your results be affected by kv  0?(3 marks)d) Comment on the likely characteristics of the ground motionrepresenting kh = 0.1(3 marks)3. Provide evidence and calculations for an offshore pile able to resist avertical load of 8 MN. Your design should be based on the ICP method andassume a 30 m water depth to the soil profile characterised by the CPT resultsand additional information provided in Moodle. As part of your design youmust explicitly state the relationships between CPT data and soil propertieswhich you may use, as well as the rational for the choice. Design parameters,values and any other assumptions required must be also properly justifiedand/or explained. You must also demonstrate consideration ofinstallation/construction process as part of your design.(25 marks)Total marks [50]
