Load-bearing performance and failure behavior of multi-flange deep cement mixing columns
Abstract
The increasing demand for infrastructure development in coastal and offshore regions has led to the pursuit of sustainable and resilient engineering solutions. This study presents a novel deep cement mixing (DCM) column with multiple flanges and investigates its potential through a three-dimensional numerical simulation. Additionally, a parametric analysis is conducted, focusing on the failure behavior of the multi-flanged column. It is observed that a shape factor exceeding 2.725 is effective for the design of the column. Reduced flange spacing and a thickened uppermost flange exhibit a notable improvements in load capacity and settlement response, while the uniform-flanged column may constrain these advantages. The deformation observed in the multi-flange column is primarily initiated by the crushing of the pile body, followed by the deformation of the uppermost flange section. In contrast, subsequent flange sections experience reduced stress and exhibit minimal deformations; therefore, the dimension of these later flange sections can be minimized. This study provides valuable insights for the design and construction of DCM columns in challenging cohesive soil conditions.
