Composite Support Structure of Continuous Arch Internal Support Design and Calculation and Analysis of Engineering Example

Composite support structure of continuous arch internal support is a new type of maintenance structure of deep foundation. In this paper, as the cylindrical shell in the ring uniform load analytical solutions of elasticity a starting point, the design and calculations methods of composite support structure of continuous arch internal supporting are discussed. Engineering examples of composite support structure of continuous arch internal supporting in deep excavation engineering applications are analyzed and summarized. At the same time, the design parameters are provided for more engineering applications.
