IMPROVEMENTS IN THE METHODS OF DETERMINING RELATIVE DENSITY OF SOILS

Abstract

This study vas undertaken to investigates nhetber the vibration parameters giving the aura Values of density dep• end upon the physical properties of wilt and whether the pro-sently aailable relative density apparatus in India, can be modified is a simple way to that the requirements can be attic. fied. Tests vers done on tics different soils using the case eroially available restive density apparatus with a.sisple and least costing modifation so as to morass the available eccentric mass state and bswee the aeaeUration. Your of the soils Vert coupaoted 'm the aaslsa dunity values at an aooe. legation of 0.62 `, whit. one soil at an acceleration of 0.80 t. It has been found that the effect of particle taps on optimal acceleration is significantly more vhils, the flWets of unifor. site coefficient and sun diameter are more or less astligibia. Therefore, b obtain to maximum density nice ibr any Riven sell the optimal acceleration should be chosen judiciously# depnding upon the particle shape and the density aeeelsration relationship should be established. rco the ctatistial analysis tarried art, a maxis um mabar of five tests has been rec Wed to obtain the aria uar density for am given soil. As for as the method( dry or vat) 'seed, for the determination of sautes density values, either of the methods should be tried ant.
