1　城市橋梁施工的特點(diǎn)
　　只有了解城市橋梁的一般施工特點(diǎn)，方可設(shè)計(jì)出最佳的施工組織方案。因此開工前，必須認(rèn)真審圖和進(jìn)行現(xiàn)場考察并領(lǐng)會建設(shè)單位的意圖。通常城市橋梁建設(shè)有以下特點(diǎn)：
　　(1) 建設(shè)規(guī)模大，占地面積大，內(nèi)容復(fù)雜。通常一座立交橋工程包括橋梁(除主橋外，含人行天橋和通道橋)、道路、給排水(給水、雨水和污水)、電力、通訊、燃?xì)�、路燈等專業(yè)工程，工程量大，且各專業(yè)工程的相互制約影響較大，施工中須統(tǒng)籌安排，協(xié)調(diào)配合。
　　(2) 要充分考慮施工期交通組織安排，盡量避免對交通及行人產(chǎn)生大的影響。通常采用修便道或壓縮現(xiàn)

The characteristics of a city bridge construction
Only by understanding the general construction of the bridge features the city before construction organization design the best program. Therefore, pre-construction, need to carefully scrutinize the plans and conduct site visits and to understand the intention of the construction unit. City Bridge usually have the following characteristics:
(1) large scale, covering an area of great complexity. Usually a bridge overpass projects include (in addition to the main bridge, the pedestrian bridge and the channel with the bridge), roads, water supply and drainage (water supply, rainwater and sewage), electricity, telecommunications, gas, street lamps and other professional engineering, engineering capacity, and the professional engineering constraints influenced each other, the construction to co-ordinate arrangements for coordination.
(2) to fully consider the organization of the construction of traffic to avoid the traffic and pedestrians have a big impact. Repair sidewalks or compression usually is
