Three-Dimensional Analysis of Load Transfer Mechanism for Deep Cement Mixing Piled Embankment under Static and Cyclic Load

Piles have been widely used to improve the bearing capacity of soft foundation. The existing research obtains significant findings on load transfer mechanism for rigid piled embankments. However, limited studies focused deep cement mixing (DCM) embankment. To grasp characteristics DCM embankments, a three-dimensional numerical simulation was conducted in this study, which validated by measurements from field case. It found that effect soil arching reduced compared with This induced approximately 61.5% larger vertical stress transferred subsoil surface and 83–150% settlement embankment foundation system. further understand working system, factors influence were investigated. is area replacement ratio most influential factor affecting at top embankment, whereas elastic modulus pile influences earth pressure coefficient. cyclic vehicle speeds 90 km/h will lead 34% growth about 11% reduction maximum Based results, analytical equation normalized acting proposed two cases, difference range 13.8~16.7%.
