| 3. | The piled raft foundation belongs to large spacing pile foundation . each pile works similarly as single pile 沉降控制复合桩基中各单桩为摩擦桩,桩距较大,因此它的工作性状与单桩比较接近。 |
| 4. | At last , suggestions are given on the designing of vertical space between expanded branches or plates , pile spacing and disposal of pile position 最后,对挤扩支盘桩的支盘竖向临界间距、水平桩距和布桩方式的设计,提出了相应建议。 |
| 5. | On the base of single pile ' s analysis , the single pile ' s settlement is computed under the burden of adjacent pile , and give the interactive factor a " s change with different load and distance between piles 在单桩分析的基础上,计算了在邻桩影响下单桩的沉降变化,给出了双桩相互影响系数随荷载水平和桩距的变化。 |
| 6. | The distance between routine piles foundation is oversized in order to use soil ' s supporting capacity and think over the pile - soil ' s combined supporting capacity . this pile foundation is called composite pile foundation 为了发挥桩间土的承载能力,考虑桩土共同承担荷载,常规桩基的桩距被加大,这种桩基称为复合桩基。 |
| 7. | 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。 |
| 8. | 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。 |
| 9. | The relationship between mechanic characteristics of composite ground and the length , the distance , elasticity modulus and replacement percentage of piles are discussed . the results of computing analysis has been contrast to the experimental data 研究桩长、桩距、桩体模量以及置换率对单桩承载力、桩间土承载力发挥值以及桩土应力比的影响程度,并将计算结果与实测结果相比较。 |
| 10. | The relation between the length of pile and settlement and the relation between the distance of pile and settlement are worked out , which provide thereunder for optimization , then the optimization of djm pile composite foundation is done by means of ansys , the optimum length of pile and the optimum distance of pile are educed 着重对复合地基的沉降与桩长和桩距的关系进行研究,为优化设计提供理论依据。在此基础上,利用大型有限元分析软件ansys的优化设计功能对复合地基进行优化设计,求出复合地基的最优桩长和最优桩距。 |
