Abstract:In the development of urban core area now, the comprehensive development efforts of the ground and underground spaces are getting higher and higher. The high-density and high-intensity concentrated development leads to a high concentration of traffic with different characteristics, which makes the capacity of the regional road network insufficient, and then causes a series of traffic congestion problems. In view of the above phenomenon, it is an important traffic strategy for large central business district to set up underground roads reasonably, separate the ground traffic flow, and leave the ground road space mainly for public transportation and non-motorized traffic and landscape planting so as to alleviate the pressure of ground traffic and to upgrade the environmental quality of core area. Based on the design case of underground ring road of Jiaxing Financial Plaza, the construction scale, entrance and exit layout, construction mode and other aspects of the underground ring road are analyzed and studied. The common problems and design strategies under the temporary construction mode are put forward. The research results can provide reference and guidance for similar projects.
