Efficiency of pile technologies in the seismic area

Grounds and foundations, underground structures

At the beginning of 2017, the erection of multistory buildings is one of the most important problems in areas of seismic activity. The purpose of the research is to find a productive way to solve this problem. This article presents an overview of the main types of piles used in the foundation construction in seismic areas. According to the method of installation, piles are divided into filling piles, driving piles and screw piles. Since the construction in seismic areas is limited to dynamic loads, main types of piles and methods of their installation have advantages and disadvantages. The results of the review show, that the driven and bored piles are one of the most suitable for areas with periodic earthquakes. The new technologies versions of pile’s designs are presented
