| 摘 要： | 以温州浅滩一期半岛起步区首期1#地块为工程背景，对薄壁筒桩、钻孔灌注桩、预应力管桩进行现场静载荷试验，研究结果表明：在滩涂土地区，与钻孔灌注桩、预应力管桩相比，薄壁筒桩不会产生沉渣问题、桩身质量好、挤土效应弱、节约工程造价，承载力及桩顶沉降量均满足滩涂土地基加固要求，更适宜应用于滩涂土地基处理中，且在滩涂土地区，薄壁筒桩不会产生土芯闭塞效应，土芯的存在及桩顶封盖对于提高承载力具有一定的贡献，适当增加筒桩桩长可以提高承载力。

| Abstract: | Based on the region block #1 of the first-period peninsula in Wenzhou tidal land,in-situ static load tests have been conducted on thin-wall tubular piles,bored piles and prestressed pipe piles.The results indicate that compared with bored piles and prestressed piles,thin-wall tubular piles are widely use in the foundation treatment of tidal flat soil due to its advantages of no sediment,high quality,weak pile driving effect,cost-saving,meeting the requirements of bearing capacity and settlement of pile top.In addition,no plugging happens during driving thin-wall tubular pile in tidal flat soil.The soil plug and cover plate on pile top have contribution to increase bearing capacity to some extent.At the same time,in order to increase bearing capacity,thin-wall tubular pile can be lengthened appropriately. |
