摘要
海上,超长、大直径钢管斜桩,设计极限承载能力超过50MN。通常情况下是无法对这样的桩的承载力进行静载荷试验的。但由于在打桩过程中,桩端未达预定深度,需要知道实际桩的承载力情况,于是采用高应变动力检测方法来完成这一任务。该文介绍采用高应变方法检测海上超长大钢管桩承载力的一些情况。
In normal conditions , we cant use static load method to better test steel pipe piles in the ocean , which is designed ultimate bearing capacity is larger than 50 MN with super - length and super - diameter . When pile＇s tip couldnt be driven into assigned depth , we used high -strain dynamic method and got the accurate bearing capacity. This paper presented the details of this case .
