Knowledge and understanding of the topic This i s the factual foundation of the assignment. The essential facts should be accurate and broad enough in their scope to allow further application. B. Application and analysis of the topic (Module specific Skill) This i s the way in which you analyse/ examine the factual information and how you interpre t this information to add value to your answer (this could be in the form of conclusio ns, solutions, recommendations, etc.). It is also important to remember that the assessor must logically be able to follow the information in assignment submissions. C. The structure in terms of logic and coherence Submissions should have a clear start and a clear end. In formation within submiss ions should also be logical and well grouped. Report structure, Abstract, Introduction & Referencing, Result Analysis , and Conclusion & Future works. D. The use of relevant work examples and/or examples gained from further reading Suggestions for further reading are contained within the course work and indicated at the end of the course work. These reading lists are not exhaustive and candidates are encouraged to read further and reference at the end of the course work using Harvard style of referencing .

Plagiarism It is important to understand what plagiarism is and how it can be avoided. “Unacknowledged copying from published sources (including the internet) or incomplete referencing”. The following also constitute plagiarism: • Copying sections of work from a f riend/colleague. • Having a friend/family member dictate something to you. • Copying and pasting from the internet without citing the source. • Copying directly from a study text quotation without citing the source. Quotations When using quotations from books, websites or journal articles you should cite the author and the year of publication then use the quote in quotation marks . Paraphrasing Paraphrasing is where you encapsulate another pers on’s original idea, argument or conclusion in your own words. I t is still necessary to attribute those ideas to the au thor, and you can do this by using the formatting outlined abov e for direct quotations, taking care to include the author’s surname and the year of publication. Collaboration We acknowledge that you may undertake joint study with colleagues or as par t of a formal training programme. However, working with another per son to write assignments is not acceptable. Your answers must be your own and in your own words. Referencing Harvard referencing : refer to the module hand book for examples. Instructions 1. Plagiarism is a serious offence. In case of any plagiarism detected, penalty will be imposed leading to zero mark. 2. Course work and reports should be solved by the individual . 3. Course work and reports should be submitted on time and submission after deadline will be marked zero . 4. Name, student identification and title of the course work to be written clearly and legibly on the cover page . M2F21719 -Soil Mechanics September 2017 3 BNE – CON/ECE/MCE UCW – Assignment Task Description 1 An embankment for a highway 30m wide and 1.5m in compacted thickness is to be constructed from a sandy soil trucked from a borrow pit. The water content of the soil in the borrow pit is 15%, its void ratio is 0.69 and the grains specific gravity is 2.7. The specification requires the emb ankment to be compacted to a dry unit weight of 18kN/m 3. Determine, for 1km length of the embankment, the following: 1. The volume of the sandy soil from the borrow pit required to construct the embankment. 2. Calculate the total cost of transporting the required soil from the borrow pit to the embankment if the cost of transporting 1m 3 of soil is 1.5 OMR. 2 A cylindrical sample of a saturated clay was compacted to a thickness of 18mm and a mass of 170.5g. After oven drying for 24 hours, the mass was found to be 145g. if the solids specific gravity was 2.66, determine: 1. The water content and the void ratio of the compacted sample. 2. The void ratio and the water content before compaction when the thickness of the sample was 22mm.

Assume that the diameter o f the sample remains constant and the sample remains saturated. 3 Two Parallel strip footings , 2.5 m wide and 4 m apart, are supporting two walls of a building. Each footing is transmitting a distributed load of 500 kN/m 2 at a depth of 2 m. The f ootings are supported by a clay layer with following properties :  Saturated unit weight =20 kN/m 3,  Total unit weight = 19 kN/m 3  void ratio= 1.1  Compression Index= 0.5  Recompression Index=0.07  Pre -consolidation Stress= 230 KPa  Water level is at 4 m from the surface. Two years after construction a differential settlement occurred and the walls began to crack. The investigation revealed that the thickness of the clay layer is not uniform; under one of the footing the thickness of clay is 2m while under the other footing the thickness of clay is 4m. Estimate the amount of the differential settlement that occurred. 4 A circular water tank with a diameter of 30m is to be constructed on a thick layer of silt. The founding depth of the footing is 2m from the ground surface. The silt layer has an un -drained cohesion of 24kPa and unit weight of 18kN/m3. Assuming a factor of safety of 3.0, recommend the maximum height of water to which the tank may be filled without causing failure in the silt layer. 5 Soil im provement means changing the engineering properties of soil in order to improve its engineering performance. Writ a short essay discussing the term soil improvement and the common soil improvement methods. The essay should meet the following requirements:  minimum of 2000 words,  Supplemented by figures and diagrams as and proper referencing.  The referencing should follow CCE - Harvard style.  Turnitin Report must be provided.
