Analysis of Ultra-High Performance Concrete Prefabricated Support Structures
Ultra-high performance concrete,hereinafter referred to as UHPC,is the most innovative cement-based engineering material at present.The emergence of this material causes a great advancement in the performance of engineering materials.Based on this condition,this paper designs a prefabricated structure for foundation pit support,and gives a formula to solve the structure stiffness based on the equivalent stiffness theory,then analyzes its support stability and bearing capacity characteristics,and subsequently concludes that it meets the relevant specification requirements.Finally,the structure is used in a foundation pit of Taiyuan Wusu Airport,and it meets the requirements through relevant calculations,which confirms the feasibility of the structure in practical project.
