Because of its light structure, simple processing and relatively low cost. Applicable to soft soil foundation areas, the foundation bearing capacity is poor or the construction environment such as the bracket method is not suitable. The construction is highly operable, and the support steel pipe can be saved in a large amount, thereby reducing the cost of construction. However, with the application of the high pile vertical frame pier structure in the upper reaches of the Yangtze River, its force form has developed into a two-way force support. As the core of the support system, the force of the steel hoop is more complicated. Force mechanism and mechanical properties of steel hoops under complex loads So far, there is no recognized and authoritative analysis. Based on the engineering examples, this paper focuses on the analysis of the steel hoop force and the construction process, and hopes to play a reference role in the construction of similar projects.
