Soil mechanics - Study guides, Class notes & Summaries

Principles of Soil Mechanics questions and answer A+ content 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 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) tr...

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...

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...

Soil correct answers This is an uncemented aggregate of mineral grains and decayed organic matter (solid particles) with liquid and gas in the empty spaces (voids) between the solid particles. Soil correct answers This is used as a construction material in various civil engineering projects, and it supports structural foundations. 1. Origin 2. Grain-size distribution 3. Ability to drain water 4. Compressibility 5. Shear strength 6. Load-bearing capacity correct answers Six soil proper...

Geotechnical Engineering correct answers Broader term for Soil Mechanics Soil Mechanics correct answers one of the disciplines of civil engineering that involves the study of soil, its behavior and application as an engineering material. Soil Mechanics correct answers is the application of laws of mechanics and hydraulics to engineering problems dealing with sediments and other unconsolidated accumulations of solid particles produced by the mechanical and chemical disintegration of rocks r...

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...

What is a settlement? CORRECT ANSWER a displacement caused by a change in stress What is the symbol for settlement? CORRECT ANSWER δ What are the three different types of settlements? CORRECT ANSWER -> Distortion -> Consolidation -> Secondary Settlement What is the equation for total settlement? CORRECT ANSWER δ = δd + δc + δs δ-> Total Settlement δd-> Distortion Settlement δc-> Consolidation Settlement δs-> Secondary Settlement What is Distortio...

Geotechnical Engineering correct answers The Civil Engineering practice begins with? SOIL MECHANICS correct answers - a discipline that applies the principles of engineering mechanics to soils to predict the mechanical behavior of soil. GEOTECHNICAL ENGINEERING correct answers 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 (Coduto 1998) SOIL SAMPLES correct answers COM...
