| 1. | It was proved that the m - value of soil is the most important parameter of effecting the displacement of retaining structure
第四，讨论了被动区土体加固对围护桩位移内力的影响。 |
| 2. | The influences of fender piles on pile cap reactions , settlements , moments and twist moments of raft are discussed herein
讨论了考虑围护桩作用对桩顶反力、沉降及筏板弯矩、扭矩所带来的影响。 |
| 3. | In previous study of the combined action of engineering piles and fender piles , piles are assumed to be straight lines without thickness in subsidiary stress computation , which will often cause errors to various degree
在工程桩与围护桩共同作用分析中，将要大量地计算桩身阻力在土体中引起的竖向附加应力和压缩量。 |
| 4. | Apgr , a program developed for analysis of combined action of engineering piles and fender piles based on the analysis method presented in this paper , is used to compute the behavior of a 30 - story building in frankfurt clay
根据文中介绍的计算理论编制的工程桩与围护桩共同作用分析程序( apgr )计算了一幢位于法兰克福粘土上的30层建筑物的情况。 |
| 5. | ( 5 ) the monitoring results of horizontal displacement along the pile in length indicate that pile bottom is not a fixed end as assumed . displacement also occurs on the pile bottom . assuming pile bottom as a elastic support will be more correct
( 5 )由桩身沿深度的水平位移监测结果可以看出，围护桩桩底并未如通常所假设的那样为固定端，在其底端也有位移，围护桩底端假设为弹性支座才更符合实际情况。 |
| 6. | This layout can transform the axial force of circular beam into a force which parallels the axial . compression strength of the concrete on circular beam can bring into play adequately . the displacement of the pile top will also reduce effectively
( 2 )设计中将围护桩按拱形布设，将垂直于圈梁的轴向力转化为平行的轴向力，充分发挥了圈梁混凝土的抗压强度，有效地减少了围护桩的桩顶位移，提高了围护结构的整体稳定性。 |
| 7. | ( 3 ) rock bolts are used as an extension of the supporting piles . this structure solves the embedding problem of cantilever pile and is newly applied in foundation trench in china . no environment contamination appears in this old crowed town because no detonation or mechanical drilling
( 3 )利用岩石锚杆作为围护桩的延伸成功地处理悬臂桩嵌固的问题，该结构方式的应用为国内首例，避免了在旧城镇老房屋密集区基岩爆破和机械成孔对周围环境的影响和污染。 |
| 8. | 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。 |
