| Abstract: | The basic composition and characteristics of flexible supporting structure with prestressed anchors are introduced. Based on the simple circleular slice, the model for safety factor of internal overall stability of this supporting structure is established. The influences of the design parameters of prestressed anchor on the stability of supporting structure are analyzed, including anchor body diameter, horizontal inclination angle, horizontal spacing, vertical initial distance and vertical spacing of anchor. This paper will provide some references to the design and construction of frame flexible supporting structure with prestressed anchors. |
