沉降

Thus, at sites where down-drag forces could overload piles beneath a traditional abutment or require heavier pile sections to carry the added load, MSE abutments will be virtually unaffected by the settlement, built at lower cost, and will require less maintenance during the bridge's service life.

因此，常规的桥台，如果出现负摩擦力会使桩体超载或需要更大的桩断面来承受外力，而MSE桥台则基本看不到沉降的影响，施工费用低、维护费用少。

Second, considering the influence of well resistance, smear effect and structure breakage of thick soft clay, the equivalent calculation method is proposed. That is, the partially penetrating sand drain ground is viewed as the double-layered ground, and its consolidation is analyzed with 1-D consolidation theory, through the transformation from 3-D consolidation to 1-D consolidation in the region of sand drain. This can overcome the disadvantage that the excess pore water is discontinuous between the region of sand drain and under-lying soft layer. To the double-layered ground, based on the consolidation mechanism under surcharge, the excess pore water pressure calculation formula is deduced under the condition of multilevel equably loading or unloading, which perfects the consolidation theory.

然后，在充分考虑竖井区井阻、涂抹作用以及土体结构损伤破坏对固结影响的基础上，将未打穿竖井地基合理地转化为双层地基，按一维固结理论计算，克服了传统固结计算方法在竖井处理区与下卧层交界面处存在孔压间断的缺点；在此基础上，从超载预压法的基本原理出发，分析了双层地基超载预压固结、沉降机理，推导了多级等速加、卸载情况下双层地基的固结计算公式，进一步完善了双层地基固结理论。

The paper focuses on the load distribution and load transfer among soil, pile-core and pile-socket, the interactive behavior of cement-soil ring and reinforced concrete core and some corresponding factors influencing the displacement of the pile which include the various core length, the section radius, the elastic modulus of soil and cement–soil etc.

着重分析了砼芯水泥土搅拌桩的竖向荷载在桩身内外芯和桩土各部分间的分配，砼内芯桩与水泥土外芯桩在荷载传递过程中的相互作用和共同工作特性，以及影响单桩沉降的因素包括砼内芯的直径和长度、水泥土和桩周土体的弹性模量等。

The water produced in the reactions did not need to be removed during the reaction because BF4 was miscible with water while the acetals or ketals were immiscible with BF4. Hence the product could be separated conveniently bydecanting.

反应中生成的水不需要被除去，因为反应中生成的水会被BF_4吸收，而大部分缩醛、缩酮产物则不溶于BF_4，可通过简单的重力沉降分离，离子液体仅需简单减压除水后即可循环使用。
