In recent years, Prestressed Concrete long piles are universally adopted. Last year such kind of pile with length up to 27~M have been produced in this country. Now in order to meet the requirements of Shanghai Harlour works and Yangtze River Bridges, we work out a new type of prestressed concrete hollow pile of 36~M long, with a cross-section, of 55 cm square (inner diameter 40 cm.) By using temporary prestressing fittings on pick points with automatic adjustment for prestress, the pile...

In recent years, Prestressed Concrete long piles are universally adopted. Last year such kind of pile with length up to 27~M have been produced in this country. Now in order to meet the requirements of Shanghai Harlour works and Yangtze River Bridges, we work out a new type of prestressed concrete hollow pile of 36~M long, with a cross-section, of 55 cm square (inner diameter 40 cm.) By using temporary prestressing fittings on pick points with automatic adjustment for prestress, the pile is suitable for two points pick, which gives great facilities to handling and transpotation. Besides, 18% of steel saving can still be made. This paper only presents the principle and calculations. The testing results will be given later.

年来预应力混凝土长桩在各国已广泛采用,我国在去年大躍进中亦已试行生产应用,长达27公尺,最近我校预应力混凝土桩科研小组在响应党的的科研结合生产的号召下,为上海码头工程及长江大桥工程进行36公尺的预应力混凝土长桩研究,并提出一种新的型式,既可节省18%的钢筋又可允许用两点吊运,这将给予施工方面极大便和。现在与上海筑港局协作进行试制与试验,兹特将原理部分报导,希望大家提出意见以便修正改进,至其试验报告则将于以后陆续发表。

Based on the tests in situ and model tests, the effect of compacted soil during pile installation in clay with different densities of compacted soil is presented in this paper. It is found that the skin friction on the shaft of pile is increased accordingly with the increase of the density of compacted soil.The installation of piles is assumed to be a problem of plane strain of the enlargement of cylindrical hole, The calculated stress variation of the compacted soil around the piles is in good agreement with...

在沉入粘性土中不同挤土密度的桩的现场试验和模型试验的基础上,本文阐述了桩的挤土效应——桩侧摩阻力随着桩的挤土密度ρ的增大而增大。 本文把桩的沉放过程假定为圆柱形孔洞扩张的平面应变问题,计算出桩周土体的应力变化与模型试验实测到的应力变化相比较,得到了较满意的结果。 本文根据桩的挤土效应,提出了大直径开口管桩极限承载力的计算方法,可供工程设计人员参考。

Hollow-pile porous breakwater is a sort of lower reflecting ones.In this paper the function of reflection coefficient of waves is derived theoretically, based on linear superimposition concept of regular reflection and incident waves and employing the total flow rate continuity of integral form instead of the non-continuity of the boundary condition.Based on the linear waves results and using the theory of linear wave spectrum, the interaction between random wave and porous breakwater is also analysed.Comparisons...

本文从规则波的研究入手,基于反射波与入射波势函数线性叠加的概念,利用积分形式的流量连续性条件来处理透空堤面上的间断边界条件,确定了规则波与管式透空堤相互作用时的反射系数。在此基础上,利用线性海浪谱的概念,分析了海浪与管式透空堤的相互作用问题。通过对模型试验结果的分析表明,本文提出的理论与实验结果符合良好。
