Abstract：The effect of fiberglass anchor on controlling surrounding rock deformation is studied in this paper. The glass fiber anchor is a kind of new type of tunnel face reinforcement technology, which can control the deformation of the surrounding rock well and improve the stability of the surrounding rock. In this paper, the numerical simulation method is used to analyse the effect of glass fiber anchor on controlling face stability inTaoshuping soft ground tunnel which is in Lan-Yu Railway line. The results show: (1)the glass fiber anchor can improve the physical and mechanical parameters of the surrounding rocks in front of the face, so as to improve the safety of the construction. (2)The effect of extrusion deformation can be reduced more than 40% by using the glass fiber anchor. (3)The actual effect of glass fiber anchor is closely related to the design parameters, and the use of anchor density 0.75/m2, anchor length of 14 meters in this project will have the best deformation control effect.
