摘要
本文介绍一种新的静压桩试桩方法———隔时压桩试桩法,即试压桩后间隔2·0h即进行单桩极限承载力测试,然后选择能满足设计要求的压桩力作为工程桩施工时的终压力。用这种试压桩确定的终压力来指导工程桩的施工,既能满足单桩设计承载力要求,又不致产生不必要的浪费。
The paper introduces a new static P.H.C.T.P. (Prest re ssed High-strength Concrete Tubular Piles) trail method. The quintessence of this me t hod:① Pushing down a pile with certainty pressure ② interval 2.0hours ③ push i ng down the pile again and measuring utmost pressure at that time. ④confirming final pressure by utmost pressure. The method could save on the construction ma t erial, abridge the engineering period. In the same time, the bearing capacity c o uld satisfy the design requirement.
