The present application discloses a prestressed tube section structure and a construction method thereof. The prestressed tube section structure includes multiple successively connected segments. A shear-resistant structure and a water stop system are arranged between two segments; multiple prestressing tendons are arranged in the tube section along the circumferential direction of the tube section; and each prestressing tendon is communicated along the longitudinal direction of the tube section, and is partitioned into multiple sections at a position close to a segment joint. By the arrangement of the multiple successively connected segments of the present application, the shear-resistant structure and the water stop system are arranged between the two segments, so that a portion between two segments may bear a shear force and have watertightness; the arrangement of the multiple prestressing tendons in the tube section enables the multiple segments to be connected in series and spliced into a whole; in addition, each prestressing tendon is partitioned into multiple sections at the position close to each segment joint, so that the tube section has higher flexibility on the premise of not losing the overall rigidity, and the loading capacity and deformability of each segment are effectively improved; and a proper pressure is applied between two segments, so that the tube section has higher deformability to adapt to a subsea foundation bed.
