Abstract: The anti-pulling mechanism of soil-nailing supporting system in foundation pit is analyzed and discussed; and a new viewpoint about anti-pulling mechanism is put forward. Anti-pulling force in soil-nailing supporting system mainly originates from two parts: the nail-soil interaction and the self-supporting of soil. In the supporting system, soil-nailing, as a force transfer component, firstly transfers the anti-pulling force originating from the self-supporting of soil; then gives other force by the nail-soil interaction. The total anti-pulling force in the supporting mechanism is determined by solving theoretically the two anti-pulling forces respectively. Finally, an engineering case is introduced to prove the reasonability of the anti-pulling mechanism; and its theoretical solution is suggested.

Key words: soil-nailing, supporting system, anti-pulling force, nail-soil interaction, self-supporting
