Various the low noise & vibration pile methods were developed and used in many construction sites. Low noise & vibration pile methods must be used essentially from the sites where popular complints would be expected. In this paper, low noise & vibration pile methods and screw pile methods were investigated, noise & vibration-free screw PHC pile method, also, was studied and its constructibility and applicability were analyzed.

In doing the foundation work in the downtown, the popular complaints by means of Noise and vibration have been became heavy burden. Therefore, the noise & vibration-free screw PHC pile method will contribute to the foundation work by removal of the popular complaints and improvement of the constructability. In this paper, the load bearing capacity and displacement characteristics of the noise & vibration-free screw PHC pile were analyzed. The noise & vibration-free screw PHC pile's behavior was better well than the existing PHC pile's one.

A FE analysis of a noise & vibration-free screw PHC pile constructed into an in-situ site were performed. During constructing a screw PHC pile, the component stresses, maximum stresses of pile connecting parts and relative displacements of pile were analyzed.

Noise & vibration-free screw pile method is being developed for solution of noise and vibration problem in existing pile method. In this paper, prior to pilot test construction, conditions which a PHC pile and a screw PHC pile were constructed into ground were modeled by finite element code and through the parametric study in cohesive soils, the behaviors of two kinds of pile according to soil characteristics were compared.

In this study, a new noise & vibration-free screw concrete pile method that was expected environmentally friendly method was introduced, also the numerical analyses of a conventional PHC pile and a new screw concrete pile were done. As a result, the bearing capacity behavior and the settlement behavior of 2 kinds of concrete pile were analyzed and compared.
