ABSTRACT

In this study, field pullout test has been conducted to reinforce the ground with micropiles. Numerical analysis was performed to estimate the optimum length of anchorage of micropiles using the load-displacement results. Various existing theoretical and empirical equations were used to estimate the allowable capacity of micropile anchoraged at the weathered rocks underneath sedimented deposits. Different values of pullout capacity in order of 10 times were found to obtain so that cares should be paid to use to estimate the capacity appropriately. As results of numerical analyses by applying the typical values of ground condition and properties of micropiles, similar results of load and displacement relationship of micropile to field test result were obtained. On the other hands, parametric numerical analysis with changing the anchorage length of micropile was also performed to find the optimum anchorage length for the given design load.
