综合管沟结合广州南站地下空间设置的优化设计

Optimization Design of Municipal Tunnel Combining with Underground Space in Guangzhou South Railway Station

广州南站地下空间设计由于受到现状地下已运营的地铁2号线路和正在建设的地铁7号线路的埋设高度限制,地下空间及对应的主要市政道路标高的设计条件都受约束,对应的市政管线布置严重受影响,因此必须结合地下空间对市政管线进行优化设计。优化方案提出设置综合管沟与地下空间相结合,其优点在于:管线统一管理维护,较少路面多次开挖情况,管线设置近、远期相互结合。

Because of buried height restrictions of the operated metro line 2 and metro line 7 under construction, the design conditions of underground space in Guangzhou South Station and the corresponding main municipal road elevation were constrained, and the corresponding municipal pipeline layout was seriously affected, so the design of the municipal pipeline combining the underground space must be optimized. The optimization scheme of combining the municipal tunnel with the underground space was put forward, and its advantage is as followsthe unified management and maintenance of pipelines, less excavation of road surface and mutual combination of short-term and long-term pipelines.
