The invention discloses a prestressing-force concrete tower structure and a construction method thereof. The structure comprises tower segments, and a group of the tower segments which are sequentially connected with one another in the vertical direction are arranged; the tower segments comprise lower connecting ring segments, middle ring segments, and upper ring segments from top to bottom; lowerportion pre-embedded members are arranged at the positions, close to the bottom faces, of the inner side faces of the lower connecting ring segments, and top connecting reinforced bars are reserved on the top faces of the lower connecting ring segments; upper portion pre-embedded members are arranged at the positions, close to the top faces, of the inner side faces of the upper connecting ring segments, and bottom connecting reinforced bars are reserved on the bottom faces of the upper connecting ring segments. According to the tower structure, the adjacent tower segments are connected through the lower portion pre-embedded members of the lower connecting ring segments above and the upper portion pre-embedded members of the upper connecting ring segments below, and the technical problemsof higher cost and longer construction period of a traditional prefabricated prestressing-force concrete tower structure are solved.
