Abstract

At present, Chinese scholars have not conducted research on the design methods and calculation theories of cement mixing pile foundation treatment under American standards. This paper analyzed and discussed the design methods and calculation steps of deep cement mixing piles for soft soil foundation by the Federal Highway Administration of the United States, and compared the differences in cement mixing pile design between Chinese and American standards to provide technical references for American standard research and geotechnical engineering design in regions obeying American standard.
