摘要对桥墩纵向刚度进行计算，分析影响桥梁下部结构刚度的主要因素，包括桩径、桩间距以及墩截面几何尺寸。 |
| 6. | Also the influences of the length , diameter , and the ratio of the stiffness of pipe to the stiffness of soil on the bearing mechanisms are discussed . based on these , some useful conclusions are reached
然后从桩长、桩径以及桩土刚度比等角度分析了其对单桩承载力、内外侧摩阻力、桩端平面应力分布、轴向荷载传递、桩身截面位移等的影响。 |
| 7. | Once the grouting technique being applied , diameter and length of pile can be decreased . pile ' s tip can be directly laid in gravel and construction work can be cut down , which means lower construction difficulties and less expenditure
采用桩端压力灌浆技术，可以减小桩径、缩短桩长，将桩端位于卵石层或减少卵石层中工作量，从而降低施工难度，减少工程投入。 |
| 8. | Some conclusions relating to the displacement group effect are obtained from simulating the influence of several factors . the results prove that the model can consider both the effect of clusters piles and the ratio of loading share of each pile
通过大量的模型计算，讨论了桩距、桩数、桩径和桩长对群桩效应的影响，还研究了群桩中各桩受力的不均性，得出了一些有益的结论。 |
| 9. | Furthermore , it was shown that load - displacement of pile groups and load distribution on pile top were affected by properties of soil and stiffness ratio of piles to soil , and by length , diameter , spacing , and number of piles
在此基础上，分析了刚性承台条件下超大群桩基础的荷载位移曲线变化规律以及桩顶荷载分布规律受桩土刚度比、桩长、桩径、桩距、桩数、土性等因素的影响规律。 |
| 10. | As the pile group with variant pile diameters and pile lengths differs in composition from the conventional pile group with identical single piles , the combined action of engineering piles and fender piles is most important for mechanism of the technique of one pile with three usages
由于桩长、桩径不同的桩组成的群桩与传统的由几何条件相同的桩组成的群桩在构成的形式上有所不同，因此围护桩与工程桩共同作用理论是“一桩三用”技术中需要重点研究的内容。 |
