Impact of Stone Column Installation Techniques on Soil Properties

Abstract

The improvement of soil bearing capacity is critical for ensuring the stability and longevity of structures built on weak or compressible soils. One effective ground improvement technique is the use of stone columns, which enhance the load-bearing capacity of soils by providing vertical reinforcement. This study investigates the mechanism of stone columns in improving soil strength and stability through a comprehensive review of existing literature, laboratory experiments, and field case studies. The effectiveness of stone columns is evaluated based on parameters such as column spacing, length, diameter, and the properties of surrounding soils. Additionally, the impact of different installation methods and materials on performance is examined. The findings demonstrate that stone columns significantly reduce settlement and increase the bearing capacity of weak soils, making them a viable solution for various construction applications. The study also highlights the importance of proper design and installation practices in maximizing the benefits of stone columns. Overall, this research provides valuable insights into the application of stone columns in ground improvement, contributing to the development of more resilient and sustainable infrastructure.
