Abstract:Research purposes:In metro construction, there are lots of connections between platform screen door(PSD) and other systems. Especially the connection between PSD and civil engineering is very important. Whether the full condition is remained or not will directly affect PSD installation. Based on construction of Line 9 of Shanghai metro, this paper summarizes the experiences and lessons regarding the metro construction, and analyzes the advantages and disadvantages of different PSD installation modes for optimizing the design and installation of PSD.
Research conclusions:The adaptability of remained condition for PSD installation in civil engineering to the unknown sizes of vehicle before construction should be fully considered. PSD can be positioned by the continuous groove remained on platform and continuous steel I-Beam remained on the top for PSD installation. The construction error exists objectively, therefore, on one hand, the construction accuracy must be improved, on the other hand, some remedial measures should be taken so as to meet the PSD installation requirement.
