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....

CORRECT ANSWER Engineering behavior classification What type of soil classification systems is USCS? CORRECT ANSWER Engineeri...

Soil mechanics correct answers is a discipline that applies the principles of engineering mechanics to soils to predict the mechanical behavior of soil. Geotechnical Engineering correct answers is the branch of civil engineering that deals with soil, rock, and underground water, and their relation to the design construction and operation of engineering projects. Shallow Foundations correct answers for transferring building loads to underlying ground mostly for firm soils or light loads ...

A clay soil has a liquid limit of 60%, a plastic Limit of 20% and a natural, in situ water content of 25%, The clay in the natural, in situ state would likely: a) be normally consolidated b) have a high compressibility c) have a stiff consistency d) have a soft consistency CORRECT ANSWER have a stiff consistency An Aeolian soil is a soil which is formed by: a) deposition of soil particles along or a base of a slope by gravity b) transportation and deposition of soil particles by win...

Soil correct answers defined as the uncemented aggregate of mineral grains and decayed organic matter (solid particles) with liquid and gas in the empty spaces between the solid particles. Soil correct answers used as a construction material in various civil engineering projects, and it supports structural foundations. Soil Mechanics correct answers branch of science that deals with the study of the physical properties of soil and the behavior of soil masses subjected to various types of ...

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...

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...
