对桥梁通航孔及相邻水中墩设安全防撞装置必要性论述

该文通过最早建成的四座长江大桥建设中和营运中发生的船撞桥事故的统计和实例,说明桥墩建筑在原来是船舶航道的位置上,在船撞桥事故中,船处于弱势地位。船舶因水位涨落、气候变化、人员操控等原因造成偏航,应该对通航孔两侧及其邻孔的桥墩,设置缓冲安全装置,既保护桥又保护船。从而对发展经济、保护环境、保护人民生命财产安全都是有利的。

Discussion on Necessity to Install Safe Anti-collision Facilities at Shipping Span of Bridge and in Neighboring Water

According to the statistics and cases of the accidents that the vessels bumped four early built Changjiang River bridges in the construction and operation,the article explains that the vessels are at the disadvantage status in these accidents caused by the bridge spans being constructed at the original vessel sea-route. The vessel leeway happens because of water level eat and flow climate change,person operation and so on. It is necessary to install the buffering safe facilities at both sides of the shipping span and their neighboring spans,which protect not only the bridges and but also vessels so as to be favorable for developing the economy,protecting the environment and protecting the safety of the people's life and possession.
