Soil - correct answer Is defined as the uncemented aggregate of mineral grains and decayed organic matter(solid particles) w/ liquid and gas at the empty spaces between the solid particles. Soil - correct answer Is used as construcion material in various civil engineering projects, and supports structural foundations Soil mechanics - correct answer Is the branch of science that deals with the study of physical properties and the behavior of soil masses subjected to various type of force. Soil engineering - correct answer Is the application of principles of soil mechanics to practical problems. Geotechnical engineering - correct answer Is the subdiscipline of civil engineering that involves materials found close to the surface of the earth. Geotechnical engineering - correct answer Application of principles of soil mechanics and rock mechanics to design of foundation, retaining structures, and earth structures River - correct answer Ancient civilizations flourished becaused of this Nile - correct answer River in egypt Tigris and Euphrates - correct answer River in mesopotamia Huang ho/yellow river - correct answer River in china Indus - correct answer River in india Dykes - correct answer Built for protection, irrigation. Pakistan - correct answer Mohenjo dara today Isolated pad footings and strip-and-raft foundstions - correct answer Used by ancient civilization for building structures Pyramid - correct answer Built as tomb for pharaohs 138 - correct answer No. of pyramids in egypt as of 2008 W=15,700 metric tons D of base= 20m H=54m Deg of tilt =5 - correct answer Specifications of tower of pisa W=4210 metric tons H=48m Deg of tilt = 4 - correct answer Specs of garisenda tower W=7300 metric tons H=97m Deg of tilt= 1.3 - correct answer Specs of asinelli tower 1. Pre Classical 2.Classical soil mechanics - phase 1 3. Classical soil mechanics - phase 2 4.Modern soil mechanics - correct answer 4 major periods of soil mechanics Preclassical Period of Soil Mechanics - correct answer This period concentrated on studies relating to natural slope and unit weights of various types of soils as well as semiempirical earth theories. Henri Gautier() - correct answer Studied the natural slopea of soils when tipped in a heap for formulating the design procedures of retaining walls. Angle of repose - correct answer Also called as natural slope 31 deg and 45 deg - correct answer Natural slopes of dry sand and ordinary earth 18.1 kn/m3 and 13.4 kn/m3 - correct answer Unit weight of clean dry sand and ordinary earth Bernard Forest de Belidor - correct answer He proposed a theory for lateral earth pressure on retaining walls. 16.7kn/m3 - correct answer Unit weight of firm or hard sand 18.4kn/m3 - correct answer Unit weight of compressible sand 16.0kn/m3 - correct answer Unit weight of soft earth(primarily silt) 18.9kn/m3 - correct answer Unit weight of clay Francois Gadroy - correct answer He observed the existence of slip planes in the soil at failure during a laboratory test during 1746 Jean Rodolphe Perronet() - correct answer Studied slope stability around 1769 and distinguished between intact ground and fills. Soil Mechanics in Engineering Practice by Karl Terzaghi - correct answer Following are the Highlights of ISSMFE in 1936 Classical Soil Mechanics- Phase I - correct answer In this period, practically all theoretical considerations used in calculating lateral earth pressure on retaining walls were based on an arbitrarily based failure in soil. Charles Augustin Coulomb() - correct answer He used the principles of calculus for maxima and minima to determine the true position of sliding surface in soil behind retaining wall. He used laws of friction and cohesion for solid bodies. Claire Marie Riche de Brony() - correct answer He included Coulomb's theory in his leading textbook, Nouvelle Architecture Hydraulique Vol. 1 Jacques Frederic Francais() and Claude Louis Marie Henri Navier. - correct answer They studied cases related to inclined backfills and backfills supporting surcharge. Jean Victor Poncelet - correct answer He extended Coulomb's theory by providing a graphical method for determining the magnitude of lateral earth pressure on vertical and inclined retaining walls with arbitarily broken polygon ground surfaces. Jean Victor Poncelet - correct answer He use the symbol phi for soil friction angle and provided the first ultimate bearing capacity theory for shallow foundations. Alexandre Collin - correct answer He provided the details for deep slips in clay slopes, cutting and embankments. William John Macquorn Rankine - correct answer He simplified Coulomb's theory. This study provided a notable theory on earth pressure and equilibrium of earth masses. Henri Philibert Gaspard Darcy - correct answer He published a study on the permeability of sand filters. He also defined the term coefficient of permeability(or hydraulic conductivity) Joseph Valentin Boussinesq - correct answer He developed the theory of stress distribution under loaded bearing areas in a homogeneous, semiinfinite, elastic and isotropic medium. Osbourne Reynolds - correct answer He demonstrated the phenomenon of dilatency in sand John Clibborn and John Stuart Beresford - correct answer They studied the flow of water through sand bed and uplift pressure. T/F - correct answer Clibborn's study was published in the Treati
