摘要
自平衡法是一种新型的桩基承载力测试方法,与传统静载荷试验方法相比具有许多优点。采用自平衡试桩法对东南大学江宁九龙湖校区研究生公寓的3根预应力混凝土管桩进行了承载力测试,并成功地探索出回收荷载箱并可再次利用的新型测试方案。研究结果表明,自平衡法在管桩测试中取得了较好的效果,可为设计提供可靠依据。
As a new method to test pile＇s bearing capacity, self-balancing method has many advantages over the traditional ones for static loading test. It was employed in testing the bearing capacity of 3 prestressed high-strength concrete pipe piles in the graduate apartment at Jiulong Lake campus of Southeast University in Jiangning District, and a new testing program by which load cell could be recycled was worked out successfully. The research result indicates that this method has achieved good effect in bearing capacity test of PHC pipe pile, and may provide a reliable basis for the design.
