What is the definition of Shear Strength CORRECT ANSWER The largest stress a soil can take without failure (the greatest stress the material can sustain) What is the definition of shear CORRECT ANSWER The failure mode due to the compressive forces What are the two design criteria that must be satisfied CORRECT ANSWER Ultimate Strength must be large enough so FS = 1 (in reality FS should be greater than 1) Serviceability limit, usually less than 1" of settlement Is having a FS of 0....

soil CORRECT ANSWER the uncemented aggregate of mineral grains and decayed organic matter (solid particles) with liquid and gas in the empty spaces between the solid particles mechanics CORRECT ANSWER branch of physics dealing with force and motion soil mechanics CORRECT ANSWER engineering science that deals with the study of the physical properties of soil masses subjected to different forces weathering CORRECT ANSWER, the process of breaking down rocks by mechanical and chemical proce...

What happens during fill operations? CORRECT ANSWER When fill operations are taking place the new soils are usually compacted in place to improve the strength characteristics. What is compaction CORRECT ANSWER Compaction in general terms is the densification of soil by the reduction in voids (mainly air) by mechanical means. How do you define degree of compaction? CORRECT ANSWER the dry unit weight Describe the dry unit weight CORRECT ANSWER -> It increases with compaction -> I...

Soil Mechanics - Exam 1 questions and answers with rated content Soil Mechanics Application of static, mechanics of materials, and fluid mechanics to describe the behavior of soils Soil Weathering rocks and minerals What are the differences between sand and clay? (size, shape, strength comes from __?) Sand: larger/coarse grained, rounder, strength from frictional forces between particles Clay: small/fine grained, flat, strength from water interaction Effective stress...

Porosity CORRECT ANSWER Is defined as the ratio of the volume of voids to the total volume Degree of Saturation CORRECT ANSWER Is defined as the ratio of the volume of water to the volume of voids Moisture Content CORRECT ANSWER Is also referred to as water content and is defined as the ratio of the weight of water to the weight of solids in a given volume of soil Unit Weight CORRECT ANSWER Is the weight of soil per unit volume Dry Unit Weight CORRECT ANSWER The weight per unit volum...
