- 在沿海软土地基上建立高耸塔架，对桩基的设计要求比较严格。本文结合某工程现场试桩资料进行分析研究，从选择桩尖持力层及进入持力层的深度、确定单桩极限承载力和控制桩基不均匀沉降等方面进行了探讨，并与十几年来30余座塔型构筑物桩基沉降数据的统计结果进行对比分析。
The technical requirements should be strictly met on the design of pile foundation for high towerson the offshore soft ground. Based on a project field testing result, this paper discusses the selection offormation of resistance to pressure and its depth to determine the maximum pile load to control the un-even subsidence of the pile foundation. It also presents the subsidence data collected from more than 30towers m recent years.1996,6(6): 7-10 收稿日期：1996-2-17参考文献：
