| 1. | Besides them , the results also indicate that the surface settlements of soil behind retaining structures are related to the deformations of retaining structures
同时，围护结构变形扫掠过的体积和墙后土体下沉量具有某种相关性，扫掠过的体积越大，墙后土体下沉的体积也越大。 |
| 2. | The prototype observation shows that because settlement of soil is larger than that of piles , " arch effect " appears in the embankment so that its weight is gradually transferred from the soil to piles and pile - soil stress ratio increases
现场原型观测表明，桩间土的沉降量大于桩顶的沉降量，填土中出现拱效应，填土荷载逐渐从桩问土向桩顶转移，桩土应力比逐渐增加。 |
| 3. | The results indicate that the lower the deformations of retaining structures develop , the larger the surface settlement of soil caused by it extents , and the farther the location of the maximum settlements is away from retaining structures
经分析发现，围护结构变形越向下发展，引起的墙后土体沉降范围越大，沉降最大值的位置也越向远离墙体的方向移动，而沉降曲线呈越来越平缓的趋势。 |
| 4. | Because there are many factors that affect the settlement of soil . furthermore , the relationship between timeand settlement is very complicated . in this paper we adopt the method that called the prediction method of multi - mthod and compile a program by c + + calculated for predicting
针对地基沉降变形的影响因素众多，以及沉降与时间关系的复杂性，作者采用多种模型预测方法，并用c + +编制了部分计算程序进行计算。 |
| 5. | According to the analysis of dynamic characteristics of these seismic soil - layer structures , it was proposed that failure functions of foundation caused by strong earthquakes included liquefaction , seismic fissure filling , vibration falling , fracturing and seismic settlement of soil
根据这些强烈地震成因土层构造的动力学特徵进行分析，认为强烈地震对地基土的破坏作用有几种方式：液化作用、地震裂隙充填作用、振动塌落作用、断裂破坏作用和震沉陷落作用。 |
| 6. | The first , site experiment is carried out . the paper analyze in - situ testing data of subgrade which is made up of plain concrete pile composite foundation and agitation pile composite foundation including pore pressure , layer settlement of soils between piles , earth pressure , lateral deformations
发现正常荷载下，两种复合地基路基的受力性状不一样，用建筑垃圾填土桩距较大的素混凝土桩复合地基，浅层应力向桩体集中，并通过桩向深层扩散，桩间土与桩有较大的相对位移，桩顶和桩端的刺入较为明显。 |
| 7. | In the paper , the principle and the schemes to be selected of ground treatment have been discussed firstly . especially when the self - settlement of soil layer has not been eliminated entirely through dynamic compaction in shallow soil layer , the friction force will appear around piles . the calculating method of negative force has been discussed , too
首先，本文论述了地基处理的原则及地基处理方案的选取，特别是在采用浅层强夯未能完全消除土层自重湿陷性的情况下，桩基存在不可忽略的负摩阻力，那么，计算桩基负摩阻力时，不仅应计入湿陷性土层所产生的负摩阻力值，也应计入其上的非湿陷性土层因失去支托而产生的负摩阻力值。 |
