The invention discloses an assembled type flexible half-excavation foundation for electric transmission lines in mountainous areas. The assembled type flexible half-excavation foundation comprises an upper slab, a base and an anchor cable used for connecting the upper slab and the base. The base is formed by splicing a plurality of prefabricated slabs and is in a circular truncated cone shape. The upper top face of the base is fixedly connected with a lower anchor slab through bolts. A steel cushion plate is arranged at the top of the upper slab. The center of the lower anchor slab and the center of the upper slab are each provided with a through hole used for allowing the anchor cable to penetrate through. The bottom end of the anchor cable is connected with the base through the lower anchor slab. The top end of the anchor cable is fixed to the upper slab through the steel cushion plate. An annular baffle is arranged on the lower surface of the upper slab. The circle center of the annular baffle is identical to the center of the upper slab. According to the assembled type flexible half-excavation foundation of the structure, the lower spliced type circular-truncated-cone-shaped base is embedded under undisturbed soil, by means of the structure, the uplift performance of the undisturbed soil can be brought into full play, and the uplift bearing capacity of the foundation is substantially improved; meanwhile, through the arrangement of the annular baffle on the lower surface of the upper slab, the horizontal load resistance of the foundation is improved.
