Furthermore, the bridge tower is a combined structure with an external steel structure and concrete poured into the bridge tower, the concrete and the steel structure in the bridge tower are used for partially balancing the bending moment generated by the horizontal force of the tower top on the tower bottom, and the steel structure is used for bearing the stress generated by the bending moment at the bottom of the bridge tower.
Further, the bridge tower foundation is an enlarged foundation or a pile group foundation; the bridge tower comprises a bridge tower foundation and is characterized in that a bridge tower bearing platform is arranged at the top of the bridge tower foundation, and the bottom of the bridge tower extends into the bridge tower bearing platform and is fixedly connected with the bridge tower bearing platform, so that the stress of the bridge tower is transferred to the foundation.
Furthermore, the anchoring system comprises a support structure fixed on the bridge tower and extending out, a cable-loosening saddle fixed on the top of the support structure and a plurality of pin-type lug plates fixed on the outer surface of the bridge tower; one end of each anchor cable is correspondingly connected with the bolt type lug plate, and the other end of each anchor cable is converged and connected to the cable scattering saddle; the end part of the main cable is fixedly connected to the cable scattering saddle.
On the basis of guaranteeing stable and reliable structure, the anchor occupies less area, reduces anchor engineering cost, effectively increases the application range of the pedestrian suspension bridge under the condition that anchor arrangement is limited, and has no side cable and no anchor, so that the whole bridge is simpler and more attractive, and the requirements of partial pedestrian suspension bridge on special landscape can be met.

Detailed Description
The present invention will be further described with reference to the accompanying drawings.
Reference is made to the accompanying drawings. The embodiment comprises a bridge deck system 3, bridge pylons 4 arranged at two ends of the bridge deck system 3, bridge pylon bearing platforms 6 arranged at the bottoms of the bridge pylons 4, a bridge pylon foundation 5 and a main cable 1 arranged above the bridge deck system 3. Wherein, the both ends of main push-towing rope 1 are respectively through anchoring system 7 anchor 4 tops of bridge tower on one side of correspondence, and the bridge tower body of the tower utilizes bridge tower basis 5 to pass power and is fixed in on soil or bedrock. The main cable 1 is connected with a bridge deck system 3 of a midspan through a plurality of vertical suspension rods 2. The bridge towers 4 at two ends are inclined to one side back to the bridge deck system 3, so that the bending moment of the horizontal force of the main cable 1 at the top of the bridge tower on the bottom of the bridge tower is balanced by the bending moment of the dead weight eccentricity of the bridge tower 4 on the bottom of the bridge tower and the bridge tower foundation 5, and the structural stability of the whole suspension bridge is ensured under the condition of no side cable and no anchorage. In particular, in order to assist in ensuring the supporting effect of the structure, the bridge tower 4 may be in the form of a concrete, steel structure or reinforced concrete structure depending on different conditions such as the span, load and the like of the pedestrian suspension bridge, and in this embodiment, a combined structure of an outer steel structure and an inner filled concrete is preferable.
The bridge tower foundation 5 can be arranged into an enlarged foundation or a pile group foundation according to geological and stress conditions. The bridge tower foundation 5 in this embodiment is preferably a pile group foundation. In particular, the top of the tower-bridge foundation 5 is fixedly connected with a tower-bridge bearing platform 6, and the bottom of the bridge tower 4 extends into the tower-bridge bearing platform 6 and is fixedly connected with the tower-bridge bearing platform so that the stress of the bridge tower is transferred to the foundation.
The anchoring system 7 comprises a supporting structure 8 fixed on the bridge tower and extending towards the main cable 1, a cable-releasing saddle 9 fixed on the top of the supporting structure 8 and a plurality of pin-type ear plates 10 fixed on the outer surface of the bridge tower. One end of each anchor cable is respectively connected with the bolt type lug plates 10 in a one-to-one correspondence mode, the other end of each anchor cable is connected to the cable scattering saddle 9 in a gathering mode, and meanwhile the end portion of the main cable 1 is also fixedly connected to the cable scattering saddle 9.
