整体沉降 meaning in English
bulk settling
Examples
- Under the seismic excitation , so as to monolithic subsidence is easy to occur
在地震动的激励下，结构会发生整体沉降。 - The tectonism in this area can be divided into three phases , that is the folded basement formation and stable ancient land in pre - mesozoic , ancient land cracking phase in mesozoic , the faulted activity and subsidence phase in cenozoic
本区构造变动划分为三个大的阶段，即：前中生代褶皱基底的形成和稳定古陆发育阶段、中生代古陆裂解阶段、新生代块断活动及整体沉降阶段。 - The performances of a short pile foundation , a long pile foundation and a composite long - short pile foundation under vertical load have been calculated by using the finite element method , and the results indicates that the composite long - short pile foundation demands fewer long piles and can effectively control the average and differential settlements
分析结果表明长短桩组合桩基础不仅可以大量减少长桩用量，而且可有效地控制基础整体沉降和差异沉降，显示其良好的应用前景。 - Secondly , by using the great fem programme , analyzes the mechanism of bearing and deformation of rigid - soften composite piles foundation . draw a conclusion : exist a specific value , when the number of the rigid pile less than it , increase the number of the rigid pile , effect of reducing the settlement of rigid - soften composite piles foundation is distinct , on the contrary , when the number of the rigid pile more than it , increase the number of the rigid pile , effect of reducing the settlement of rigid - soften composite piles foundation is indistinct . finally , analyze and sum up some important design ' s constitutes of the rigid - soften composite piles foundation
其次，采用有限元计算程序，对刚柔复合桩基进行了三维有限元分析，考察了在不同荷载水平下，不同刚柔性桩比例的情况下，复合地基的平均沉降量、土体的沉降等值线和应力等值线以及刚性桩和柔性桩桩顶荷载比值随不同基础荷载水平的变化规律，得出了一些具有实际指导意义的结论：当总桩数不变，长桩比例增加到一定程度时，再增加刚性长桩的数量对地基整体沉降几乎没有什么效果；刚柔桩分布一定，柔性桩实际承载力小于其极限承载力时，外加荷载的增加，刚性单桩和柔性单桩所承当荷载的比值基本不变。
