Soft Foundation Treatment Based on Xiangjiaba Project Slag Yard

Abstract

Foundation treatment is a crucial aspect of practical engineering. A stable foundation plays a vital role in enhancing building stability, ensuring structural durability, and minimizing environmental impact. However, dealing with soft foundations presents a challenging problem in foundation treatment. This paper aims to study common methods for treating soft foundations based on data analysis, exploring the fundamental mechanisms and advantages and disadvantages of various treatment methods. Simultaneously, the paper combines new methods for treating soft foundations in China, analyzing the practical treatment of the Xiangjiaba Project slag yard. The study identifies that, in practical engineering, the overall soft layers of the site are treated using the replacement method. Sections requiring treatment employ the block-stone replacement (squeeze consolidation) method, functioning as integral structural retaining walls. Additionally, due to the local precipitation reaching 1003.1 to 1305.6mm, drainage treatment is necessary for the site. By combining these three treatment methods, the study achieves the requirements for structural load-bearing capacity and stability while simultaneously achieving the effects of shortening construction time and saving costs. This research on soft foundation treatment is beneficial for providing insights into achieving the development goals of Western China.
