| Abstract: | The practical internal force that a group of micro-piles could provide was calculated and the exact value of thrust against sliding was obtained using the anti-inference method according to the special access road landslide treatment works for construction of Jinping Hydropower Project by applying the theory of lateral compressive beam on elastic foundation.The joint reinforcement of the landslide by micro-steel pipe piles and pre-stressed anchorage cables has achieved desirable results. |
