摘　　要：在高桩码头桩基承载力检测中,经常受海上场地条件限制,传统静载荷试验无法实施,而自平衡试桩法因其试验装置简单、可大吨位加载、可对斜桩检测、场地适应性强等优点逐渐被推广应用。基于深圳某高桩码头的自平衡试桩法应用实例,分析自平衡试桩法的优势及主要存在问题,针对问题提出认识、思考和应用建议,指出荷载箱与上下桩的连接以及被顶开间隙的处理是工程桩中应用自平衡法的关键。在荷载箱埋设后上段桩仍满足抗拔承载力的情况下,自平衡试桩法可应用于工程桩;而对于非工程桩,自平衡试桩法具有广泛的适应性。In the testing of pile foundation bearing capacity of high pile wharf,the traditional static load test can not be implemented due to the limitations of offshore site conditions.However,the self-balancing pile test method is gradually popularized and applied because of its advantages such as simple test device,large tonnage loading,inclined pile detection and strong site adaptability.Based on the application example of the self-balancing pile test method in a high pile wharf in Shenzhen,this paper analyzes and summarizes the advantages and main problems of the self-balancing pile test method,and puts forward understanding,thinking and application suggestions for the problems.It points out that the connection between the load cell and the upper and lower piles,as well as the treatment of the jacked gap are the key to the application of self-balancing method in engineering piles.The self-balancing pile test method can be applied to engineering piles when the upper section piles still meet the uplift bearing capacity after the load cell is buried.For non-engineering piles,self-balancing test pile method has wide adaptability.
