Question l:State the correct answer $($True or False$)$ in your ANSWER BOOK along with the Questionnumber. Have all your answers for Question I at one place.$(10$ marks$)$Zero$-$air voids line $($ZAVL$)$ which is associatcd with the compaction curve$($i$.$e$.,$ dry density versus water content relationship$)$ is always above thecompaction curve. In addition, typically ZAVL is parallel to wet$-$of$-$optimumportion of the compaction curve.Effective cohesion value is typically larger in overconsolidated clays incomparison to the normally consolidated clays.Plasticity index $(),$ plastic limit $($PL$)$ and liquid limit $($LL$)$ values for twosoils: Soil A and Soil B are summarized below:Soil A: $,-30\%$; PIF $3070,$Soil B: I,$=30\%$; PL$-20\%$; $1$Rased on the above s tedex Chave a lower Compressioninformation of soil properties, Soil B willTwo identical saturated soil specimens were tested in a triaxial shearapparatus for determining their shear strength under consolidated drained$($CD$)$ and consolidated undrained $($CU$)$ conditions. The soil specimens testedunder CD conditions undergo more volume change in comparison to CUconditions in a triaxial test.S A soil specimen achieves $30\%$ consolidation in $3$ months at a site subjected toa load of $100$ kN$/$m$^2.$ If the site was loaded to $300$ kN$/$m$,90\%$ consolidationwould occur in a period of$9$ months.Boussinesa's equation is typically used for estimating the variation of stressin soils due to a point load with respect to depth; however, this equation is notvalid at a depth equal zero$\mathrm{.}7$ Knowledge of compression index, Ce is required for determination ofsettlement of sand.The stress versus strain behavior ofa normally consolidated clay is similar tothat of a loose sand$\mathrm{.}9$ The plasticity index $()$ of low comnpressible silt $($ML$)$ is typically lower thanhighly compressible clay $($CH$).|10$ The amount of volume change that will occur when a soil is subjected to loaddepends on the coefficient of permeability, k$,$ of the soil.TTTTTTTFFFFF
