广州地铁3号线支线拆解工程线路方案研究

简述广州地铁1、3号线换乘站体育西路站的现状客流压力，分析地铁3号线主、支线现状运营组织存在的问题，得出主、支线拆解的必要性及迫切性。由于3号线支线未预留拆解条件，且拆解点位于商业繁华的市中心，高楼密集，交通繁忙，因此需结合既有线情况，巧妙利用既有线线型，选择合适接岔点，尽量减少既有线的改造，缩短工期，减少对周边及3号线支线运营的影响，得出最优的主、支线拆解线路及土建实施方案，确保3号线主、支线拆解工程的可行性，为未提前预留条件的轨道交通拆解工程提供参考。

Scheme of the Disassembly and Demolition Project of Guangzhou Metro Line 3

This study briefly describes the current passenger flow pressure in the West Station of Guangzhou Metro, a transfer station for Line 1 and Line 3 and analyzes the existing operational problems of the organization of the main line and branch line of Line 3 to establish the necessity and urgency of dismantling the main and branch lines. The results indicate that the dismantling point is located in the bustling downtown area and not at the branch line of Line 3. However, the process is complicated as the high-rise buildings are dense, and the traffic is heavy in the downtown area. Therefore, it is necessary to combine the existing wired conditions, skillfully use the existing line type, select the appropriate connection point, and reconstruct the existing railway line such that the construction period is short with reduced impact on the operation of the surrounding lines and the Line 3 branch line. Thus, the study proposes an optimal main and branch line disassembly plan and civil construction implementation plan to ensure the feasibility of the main line and branch line dismantling project of Line 3. The dismantling project of rail transit without prior reservation conditions has been used as a reference.
