港口工程一般多处于软弱地基,所以在某些情况下采用桩基础是合理的,但有时候遇到轴向力和弯矩并不太大,而对沉降又必须控制,不能过大的情况下,一般也采用桩基础,凡每一桩台下仍然布置二根甚至三根桩,而实际上只需要一根桩即能满足要求。还有一种情况是在某些沿海地区,须将桩尖打至校深的硬土层,桩比较长,相应其承载力也大,为了充分利用桩的承载能力以收到较好的经济效果,第一桩下布置一根桩也就可以了。根据以上情 Generally speaking, harbor engineering is on a weak foundation, so it is reasonable to adopt pile foundation in some cases, but sometimes it is not too big to meet the axial force and bending moment, but the settlement must be controlled again. If it can not be too large , Generally also use the pile foundation, where each pile is still arranged two or even three piles, but in fact only one pile that can meet the requirements. Another situation is that in some coastal areas, the pile tip must be hit to a deep hard layer with a long pile and correspondingly large bearing capacity. In order to fully utilize the bearing capacity of the pile to receive good economic results, It is okay to arrange a pile under the first pile. According to the above situation
