摘要
沿海滩涂地区超厚软土层上动力设备的基础设计,其突出问题是控制基础沉降。采用下设桩基的块式基础,可通过改变桩的长径比来控制地基沉降。经过两种方案多方面对比分析发现,在沿海地区工程实例中,单纯改变桩长对基础的振动位移影响不显著,宜采用控制沉降更为有利的长短桩组合型复合基础类型进行设计计算。
Concerning foundation design of power equipment on thick soft soil layer in coastal region,the overwhelming question is settlement control.The ground settlement can be manipulated by changing the pile slenderness ratio of blocked foundation with the pile below.Comparing two schemes in several aspects,the case study shows that just altering pile length makes inconspicuous efforts to the vibration displacement of foundation in coastal areas.According to the analysis,it is appropriate to use the more reliability foundation style called rigid-flexible and long-short pile composite foundation,which is argued more available in differential settlement control,to design and calculate.
