摘　　要：以2010年上海世博会园区综合管廊工程为背景,对一个25m标准施工段内的预制预应力综合管廊和现浇整体式综合管廊的施工工期和土建成本等进行了分析与计算。结果表明,预制预应力综合管廊施工现场文明有序而整洁,具有良好的节能环保效益,总体经济性优于现浇整体式综合管廊。一个标准施工段内预制预应力综合管廊的施工工期比现浇整体式综合管廊减少约45%,土建成本降低约4%。According to the construction of municipal tunnel in 2010 Shanghai Expo Area, the construction period and the cost of precast prestressed municipal tunnel （PPMT） and cast in place municipal tunnel （CIPMT） of a 25 m construction section were calculated. Results showed that the general economic cost of the PPMT , with the advan- tages as environmentally friendly site operation and energy conservation, was lower than the CIPMT. The construction period and the cost of the PPMT of a 25m construction section were 45% and 4% lower than the CIPMT respectively.
