It is proposed to construct a new bridge across a river near Pondicherry. The soil

deposit of the river bed is fully saturated with saturated unit weight of $19\mathrm{.}5$

$k\frac{N}{m}2.$The nearby fault system in Bay of Bengal could generate a peak horizontal

acceleration, amax of $0\mathrm{.}15g$ at the site. Caissons are used as the bridge foundation.

The bottom of the caissons is at a depth of $5m$ below the riverbed.

The CPT tests were carried out at the above site. At the depth of $5m$ below the

ground, the penetration resistance at the cone tip and the sleeve were measured to be

$5$MPa and $100$kPa respectively.

During the design earthquake of magnitude $6\mathrm{.}0,$ will the saturated soil located at the

bottom of the caisson be liquefied?
