| 1. | Normally consolidated soil
正常固结土 |
| 2. | Comparison of characteristics between normal consolidated soil and over - consolidated soil
正常固结土与超固结土主要力学特性的比较 |
| 3. | The non - linearity of the foundation can be analysed by the factor of the raft - pile interaction . moreover , a factor behaviors of over consolidated soil is used
该法将基础承担上部结构的过程划分为3个阶段，用桩筏相互作用系数对沉降控制复合桩基作非线性分析。 |
| 4. | The results were as follows : for the over - consolidated soils , coefficient of the secondary consolidation increased with load ; for normal - consolidated soils , it decreased with load
结果表明：对超固结土，次压缩系数随荷载增大而增大；对正常固结土，次压缩系数随荷载增大而减小。 |
| 5. | The main problems widely seen in the previous studies are ( 1 ) inadequate modeling of initially anisotropically consolidated soil and ( 2 ) numerical vulnerability associated with the stress path in the vicinity of the failure line
以前模型普遍存在的问题有： ( 1 )不能模拟初始偏压固结的情况； ( 2 )当应力路径接近破坏线时数值稳定性差。 |
| 6. | The relationship between the secondary consolidation deformation and load were discussed and the characteristics of the secondary consolidation of normally consolidated soils were emphansized in discussion , and some rules were concluded and analyzed
本文对次固结变形与荷载的关系进行了较详细的探讨，并着重研究了正常固结土的次固结特性，且对其规律进行了总结和分析。 |
| 7. | The mechanism of rockfill rheology is rectified theoretically . as a kind of man - made discrete material , the rockfill is similar to the consolidated soil in the aspect of rheology . the main causes of rockfill rheology are the breaking and sliding of particles , filling of pores
从理论上深入论证分析了堆石流变的机理，对于堆石这种非自然存在的散粒材料，其流变与土体的次固结相类似，产生堆石流变的主要原因是颗粒破碎细化、滑移充填孔隙所致。 |
| 8. | As soon as the tunnel boring machine advances 1m forward , 6 pieces of pre - cast concrete segment are fabricated and forming a ring with internal diameter of 5 . 6m to support soil outside , while simultaneous back - filling and 32 - hole chemical grouting injector equipment installed with tunnel boring machine consolidating soil instantaneously to enhance the soil strength . the tunnel boring machine is also equipped with guided top gyroscope and true circularity retaining device for construction accuracy
其中值得一提者，板桥土城线所采用之潜盾机系新型之土压平衡式机种，具同步背填灌浆之功能，对地表沉陷之控制成效优良，目前已贯通并通过民房及商业区下方之下行隧道其初期沉陷均控制在5mm之内，二次沉陷及最终沉陷平均总量最大亦仅18mm ，远优于初始设计的警戒值30mm 。 |
| 9. | Firstly , gravel piles in soil were laid for compacting and consolidating soil , then gravel composite foundation was treated with dynamic compaction in order to form three - level soil that is gravel composite soil and high replacement ratio composite foundation and dense composite foundation
该法先在填土层中设置好碎石桩体，利用挤密和排水固结的作用使其得到初步加固，然后对荷载影响深度范围内的复合土体进行低能强夯处理，迫使桩体碎石沿径向扩散，形成上部为密实的碎石二合土层、中部为扩径后高置换率复合地基、下部为整体夯密复合地基的三层结构。 |
