为解决两线十字交叉换乘站设计中换乘易拥堵、建设地下大空间投资大以及施工期交通组织与管线迁改困难等问题，通过吸取前人研究成果，结合自身设计实践，提出采用一岛两侧站台、增加楼扶梯数量及点位、扩大站厅十字交叉区域面积、优化换乘路径等方式，使上下车乘客流线分离、换乘客流单向循环，最大程度减少客流交叉、加大缓冲区域，有效缓解换乘便捷与拥堵的矛盾；同时，借助客流仿真进行优化设计，达到大客流车站换乘的最佳效果；针对常规十字换乘站地下空间压抑、视线不通透的问题，在节点区域采用组合结构，实现大跨度、大层高设计，改善空间尺度和乘客舒适性。在节点区域采用小埋深、大空间，是在提高换乘功能、空间效果的基础上节约投资的有效途径。在十字路口下方的节点区采用盖挖逆作法，可提高深基坑的安全性，显著减小工程建设对道路交通、市政管线等外部环境的影响，并可节约大量混凝土支撑等临时结构，是一种安全、环保的建造方法。研究和实践表明： 针对城市核心区的两线十字交叉大客流换乘站，综合利用一岛两侧站台、组合结构、盖挖逆作法等方法，可以达到车站设计综合效果最优的目的。

Crossover transfer station between two lines face many challenges such as transfer congestion, the necessity of large investment to construct large underground spaces, difficult transportation organization, and complex pipeline relocation. Therefore, based on previous research results and practice, a series of countermeasures, such as adopting the "one islandtwo sides" platform, increasing the number and location of escalators, expanding the crossover area of the station hall, and optimizing transfer paths, is proposed to separate the boarding and alighting passenger flows, realize oneway circulation of transfer passenger flow, minimize passenger flow intersections, increase buffer zones, and effectively resolve the contradiction between convenient transfer and congestion. A passenger flow simulation is performed to optimize the design and achieve the optimal transfer effect at stations with high passenger flow. In addition, to solve the problems of suppressed underground space and lack of visibility in conventional crossover transfer stations, a composite structure is adopted in the node area to achieve a large span and high floor height and to improve the spatial scale and passenger comfort. Adopting a small burial depth and large space for the node areas can reduce costs while improving the transfer function and spatial effect. The cutandcover topdown method used in the node area below an intersection improves the safety of deep foundation pits, drastically reduces the impact of engineering construction on external environments such as road traffic and municipal pipelines, and reduces the need for temporary structures such as concrete supports. 〖ＪＰ+1〗Thus, these are safe and environmentally friendly measures. Research and practice have shown that the recommended technologies can achieve an optimal effect for twoline crossover transfer stations with large passenger flows.
