Parameter Design of Anti-Slide Pile Control Method in Floor Heave

Floor heave is a kind of deformation form that rock and soil mass of roadway floor enter a plastic flow state under surrounding stress. Installing anti-slide piles is an effective method to control floor heave. Considering the stress conditions and the characteristic of slip line fields in geometry size when floor heave emerges, some parameters used to design anti-slide piles are proposed to control floor heave, which will provide theoretical basis for further designs of roadway support.
