摘要	Flexible supporting system with prestressed anchors is a new technique developed from anchored retaining wall for retaining deep foundation pit or improving stability of existing slope. In order to further study the behaviors and working mechanism of the flexible supporting system with prestressed anchors, the anti-pulling force of anchor is analyzed and studied. The improved solution method of anti-pulling force of frictional grouting anchor is proposed. The study indicates that in the supporting system of flexible supporting structure with prestressed anchors, the anti-pulling force should be decomposed into two parts: the anchor-soil interaction and the soil self-supporting. In the supporting system, anchor, as a force transfer component, firstly transfers the anti-pulling force coming from the soil self-supporting; then provides other anti-pulling force by the anchor-soil interaction. The two anti-pulling forces are solved theoretically; and the theoretical calculation formulae are given respectively; then the total anti-pulling force of anchor is determined. Two case studies are introduced to prove the rationality of the solution of anti-pulling force of anchor. The values of limit anti-pulling force of anchor based on the improved solution method are larger than these of the traditional methods; and the concept of anti-pulling force solved according to the improved solution method is more clear, which further enriches the working mechanism of prestressed anchor supporting system from theoretical aspect and provides the scientific basis for engineering practices.
