薄壁筒桩在温州滩涂土地基处理中的应用研究
Research on application of thin-wall tubular piles to Wenzhou tidal flat soil foundation treatment
摘要
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.关键词
