【摘要】：隨著超大直徑單樁基礎在海洋工程中的廣泛應用,在超大的樁錘重量作用下,使得沉樁過程中溜樁現(xiàn)象頻發(fā)。工程經(jīng)驗表明,溜樁過程中,樁側摩阻力的發(fā)揮程度很小,所以對溜樁區(qū)間的判斷主要取決于對樁端阻力的評估。溜樁現(xiàn)象主要發(fā)生在黏性土層中,因此以對黏性土層樁端阻力的計算是至關重要的。針對某平臺樁基沉樁過程中的溜樁問題進行了分析計算,比較黏性土層中樁端阻力的計算方法,提出計算溜樁問題中的黏土樁端阻力的方法并驗證了其合理性,可供樁基設計以及沉樁施工參考。
[Abstract]:With the wide application of super-large diameter single pile foundation in ocean engineering, the pile-slip phenomenon occurs frequently in the process of piling under the action of super-large pile hammer. The engineering experience shows that the exertion degree of friction on the side of the pile is very small in the course of pile slide, so the judgment of the slip pile section mainly depends on the evaluation of the resistance of the pile tip. The phenomenon of pile slip occurs mainly in the clay soil, so it is very important to calculate the pile tip resistance in the viscous soil layer. This paper analyzes and calculates the pile slip problem in the course of piling on a certain platform, compares the calculation method of the pile tip resistance in the clay soil layer, puts forward the method of calculating the pile tip resistance in the pile slide problem and verifies its rationality. It can be used as a reference for pile foundation design and piling construction.
