| 3. | Through the observation on jiaozuo - gongyi yellow river bridge project in he nan province and by using the settlement data obtained in the project , the rules of uneven settlement in soft clay base there were studied in this paper 本文通过对河南境内焦作至巩义黄河大桥连接线工程软土地基两年多的现场沉降观测,使用各个断面不同位置的沉降板沉降数据,研究了软土地基不均匀沉降规律。 |
| 4. | The basic uneven settlement problem were controlled well , also the anti - liquefied problem of sand layer nearly was solved in this plan . when increasing the basic gravity after the project completion , the proportional lowering of seepage damage of sand in overburden foundation are greatly improved 基础不均匀沉降问题也能得到较好控制,防砂层液化问题也基本解决,在工程完建后增加基础压重的情况下,覆盖层基础中砂层的渗透破坏坡降也大大提高。 |
| 5. | The tower shafts , most of which are hollow and varying in cross section , and altitudinal construction bring trouble to the form work and the stress of strand wire . and the cracks on the crossbeams will be caused by the following - deformation of the bracing structure joints , elastic deformation , uneven settlement and temperature changes . the additional stress of the base slab and the foundation is caused by the deviation of cable bent tower construction 但大跨度桥梁混凝土索塔施工设备进场及现场管理都比较困难;塔柱多为空心变截面,且为高空作业,给模板工程及预应力张拉带来一定困难;支撑系统连接的间隙变形、弹性变形、不均匀沉降以及环境温差可导致横梁裂缝;索塔施工偏位会引起的承台和基础的附加应力,对加劲梁的架设影响大;悬吊结构未完体系(架设时)施工阶段的风致振动往往影响到施工的安全和质量;实心塔柱部分体积较大,易产生温度裂缝。 |
| 6. | Research results show that the settlements of the road structure mainly come from the consolidation and the accumulative residue settlements under the cyclic loads . excessive uneven settlements will produce the premature failure on the pavement . and few researches on the interaction of pavement and subgrade have been developed at present 研究表明,路面路基结构的沉降变形主要来自地基路堤土层的固结压密沉降和交通荷载反复作用下路面路基各结构层的累积残余变形,路面路基结构发生过大的沉降变形会使路面过早破坏。 |
| 7. | Because of the high horizontal and vertical loaded capacity as well as the good resistance to uneven settlement , piled raft foundations are widely used in the thick soft soils in coastal areas . as a result , the research of interactions between superstructure and foundation is a constant hotspot in the geotechnical engineering 桩筏基础因其具有很高的横向、竖向承载力和良好的抵抗不均匀沉降的能力,一直以来都是沿海深厚软土中高层建筑的主要基础形式,对桩筏基础共同作用的研究也一直是岩土工程领域的一个热点。 |
