Application of steel piles in infrastructure works

Abstract

Steel piles are widely used in the foundation construction of many infrastructure projects in Thailand, such as tall street light poles, traffic signs, road foundations and walls, etc. The distinctive design makes the load-bearing characteristics of steel piles much more complex than those of ordinary piles. The advantage of steel piles is that they can support heavy loads. A variety of applications can be installed quickly. Both noise and vibration are absent. This article presents the design concepts and load-bearing behavior of steel pile foundations in various construction projects. A comparative analysis of the foundation load-bearing characteristics of steel piles and conventional piles from field inspection. The results of the study showed that in foundations with the same diameter and length of piles, steel piles had a higher maximum load-bearing capacity than conventional piles.
