Ecological Corridor Bridge Design for Honggang Park, Shenzhen: Kunpeng Trail Bridge No. 3

Abstract

As a core node project of Shenzhen’s "Mountain-Sea-City Connectivity Plan," Kunpeng Trail Bridge No. 3 is located in Qingshuihe Subdistrict, Luohu District. The bridge represents an innovative approach to enhancing ecological connectivity in a high-density urban environment. It adopts a cable-assisted continuous steel truss structure that spans Qingshuihe 3rd Road and Metro Lines 14 and 17. By connecting the western and eastern Maling areas of Honggang Park, the bridge effectively mitigates ecological fragmentation caused by transportation infrastructure barriers. This paper systematically presents the design concepts and key technological innovations associated with the bridge, including its overall layout, structural system, stay cables and anchorage systems, human-induced vibration control, ecological protection and durability measures, and incremental launching construction methods. The study provides valuable technical references for the design and construction of similar long-span ecological corridor bridges.
