自平衡试桩法在上海铁路南站工程中的应用

在钻孔灌注桩桩基工程中,为确保工程安全,需要进行静载试验。传统的静载荷试桩法费力、费时、费钱。现通过在上海铁路南站工程中进行自平衡试桩法测试桩的承载力,并与锚桩试桩法测试结果进行对比,取得了满意的结果。测试结果表明,自平衡试桩法与常用的锚桩试桩法相比,具有节约工期、节省测试费用、对施工影响小等特点。

Application of Self-balance Loading Method in Shanghai South Railway Station

In the bored concrete pike engineering ,state experiment is carried out to guarantee the engineering safety,but the traditional state loading experiment method waste more strength, time and money. This paper applies a self-balance loading method to test the carrying capacity,and compares the result with that of anchor pile method.The author argues,because of the time and cost saving,the mild impact on the engineering,the self-balance loading method applied to Shanghai South Railway Station Engineering is a success.
