The application of ground reinforcing materials for the pile foundation

摘要

This study presents results of applying ground reinforcing materials to pile foundation for the purpose of improving the horizontal bearing capacity of the pile foundation, and the compound foundation consists of ground reinforcing material and pile. The objective of this study is to verify the effectiveness of ground reinforcing material, based on results of bearing capacity experiment using a physical model of a pile in sandy ground and numerical analysis. According to the results of the experiment and numerical analysis, it was confirmed that the horizontal bearing capacity increases in proportion to the length of ground reinforcing material and the improvement depth, which is the number of layers of ground reinforcing material. Therefore, the application of ground reinforcing material is an effective way of increasing the horizontal bearing capacity of piles.
