Abstract
The paper reports a series of centrifuge model tests on uplift behavior of manhole in liquefiable deposit. A total of six cases of model tests are reported where density of the model deposit and intensity of input accelerations are varied. Measured excess pore water pressures around the manhole model are used for computing safety factor against the threshold level for uplift. The computed safety factor and the degree of measured uplift are not consistent with each other, implying that deformation analysis such as through finite element method may be important to evaluate the degree of uplift of manhole in liquefiable deposit.
