摘要
建造浮桥的目的一般分为两类:一种是出于满足军事战备或抢险救灾的需要为目的。由于浮桥以浮动基础来代替复杂的水下固定基础,便于架设,便于拆除,更便于疏散隐蔽和装车运输,具有较突出的快速性和机动性。另一种目的主要出于经济性考虑,即当现场的水深很大或水底非常柔软时,建造传统桥墩就不太合适。而此时利用水的自然浮力,既不需要传统桥墩也不需良好地基的浮桥就成为较好的选择。
Normally,there are two aims for building a floating bridge.The first one is for the purpose of military combat readiness or emergency rescue.A floating bridge is adopting a floating foundation in stead of a complicated fixed underwater one.Being full of rapidity and motility,it is convenient for erection,remove,evacuation,and transportation.The other purpose is out of consideration of economy.When the on-site water is really deep or water bottom is soft,building a traditional pier is inappropriate.Now a floating bridge which does not need traditional piers or a nice foundation will be a better choice.
