Research Progress on Mechanical Properties of Cemented Soil under Multi-field Coupling

Cement mixing pile reinforcement technology is one of the most commonly used and effective methods for soft soil foundation treatment. The strength of cemented soil is influenced by multiple factors, and the mechanism of its strength deterioration under coupling of multiple fields is rather complex. Fully grasping the mechanical properties of cement-stabilized soft soil and its deterioration laws is an important prerequisite for ensuring the safety and stability of cement mixing pile soft soil foundations under the coupling effect of multiple fields. However, at present, there are still some urgent problems to be solved in the research on the mechanical properties of cement soil under the action of multi-field coupling. This paper reviews the current research on the mechanical properties of cement soil under the coupling effect of multiple fields at home and abroad, systematically summarizes and analyzes the solidifying mechanism and research status of cement soil under the temperature field, environmental field, stress field and the coupling effect of multiple fields, and discusses the current research deficiencies of cement soil under the coupling effect of multiple fields. This study explores potential research suggestions with cutting-edge significance, providing new thoughts and ideas for the subsequent scientific research and application promotion of multi-field coupled action in cemented soil.
