摘要

当在恶劣环境和海上应用中使用时,传统的桩材料(如钢、木材和混凝土)容易出现代价高昂的耐久性问题,例如钢筋/预应力混凝土和钢壳桩的腐蚀。玻璃纤维增强聚合物(FRP)复合材料提供了一种耐腐蚀的建筑材料。在过去的十年中,frp -混凝土复合桩已经成功地应用于几个工程中。本文研究了自固结混凝土(SCC)填充FRP复合材料锥形和圆柱形桩在封闭压力室的密砂中侧向荷载作用下的性能。采用趾部打桩和常规头部打桩的方式进行了17次桩的安装。这些桩随后进行了静侧向荷载试验。结果表明:桩锥度增大了桩的抗侧承载力,提高了桩的综合性能。引入锥度系数Ktl来解释锥度效应。

Lateral behaviour of composite tapered piles in dense sand
When used in harsh environments and offshore applications, conventional pile materials (such as steel, timber and concrete) are prone to costly durability problems, such as corrosion in reinforced/prestressed concrete and steel shell piles. Fibreglass-reinforced polymer (FRP) composites provide a corrosion-resistant construction material. FRP–concrete composite piles have been used successfully over the last decade in several projects for fendering applications. This paper investigates the behaviour under lateral loading of FRP composite tapered and cylindrical piles filled with self-consolidating concrete (SCC) and driven in dense sand enclosed in a pressure chamber. Seventeen pile installations were conducted using toe driving and conventional head driving. The piles were subsequently subjected to static lateral load tests. The results show that the pile taper increased its lateral capacity and enhanced its overall performance. A taper coefficient, Ktl, was introduced to account for the taper effect on ...

期刊介绍: The objectives of the Association shall be the promotion of co-operation among geotechnical societies in SE Asia; and the assistance to member societies who have limited number of members. Now there is only one combined web titled: AGSSEA-SEAGS. SEAGS & AGSSEA encourage the submission of scholarly and practice-oriented articles to its journal. The journal is published quarterly. Both sponsors of the journal, the Southeast Asian Geotechnical Society and the Association of Geotechnical Societies in Southeast Asia, promote the ideals and goals of the International Society of Soil Mechanics and Geotechhnical Engineering in fostering communications, developing insights and enabling the advancement of the geotechnical engineering discipline.
