结构失稳 meaning in English
buckling
Examples
- The essential of the instability is showed by mathematics method
利用数学方法揭示了网壳结构失稳的本质。 - It is very important to distinguish the qualities of the structural instability , or it is impossible to rightly measure the structural bearing capacity
区分结构失稳类型的性质十分重要，否则不可能正确估量结构的稳定承载力。 - The stability of the steel structure is an important factor leading to the structure destruction and the elastic stability of the steel frame structure is a predominant topic in the fields of steel structure
结构失稳是钢结构破坏的重要形式。钢框架的弹性稳定理论是钢结构领域中的一个主要问题，研究比较成熟，但还存在一些问题。 - At present , the difficulty of the study of tunnel include five factors , first , the unclear model , second , the indistinct criteria , third , all of the problem that we are facing being limited information , the forth , limited knowing of destruction mechanism , the fifth , much indefinites
目前隧道结构失稳研究的困难在于失稳模型不清楚，失稳判据不明确，面对的是“数据有限”的问题，且对岩体本身的破坏机理了解有限，存在大量的不确定性。 - In the paper , other research results are summarized , and a big test model indoor of row pile retaining and protecting deep foundation pit is designed . for homogeneous soil or samdwich soil structure three different retaining and protecting kinds : dense pile , thin pile and without pile are designed , using excavation simulation and loading on the top of slope , the model test is divided into two stages : foundation pit excavation simulation stage and destroy test stage . in this paper , for three different retaining and protecting kinds , the relation between soil pressure and displacement of piles , the relation between soil stress and strain , interaction of pile and soil and retaining and protecting loss - stability destroy are systemic studied
本文总结了前人研究成果，构筑大型室内深基坑排桩支护试验模型，在均质及层状土层结构地基上，设计了密排桩、疏排桩及无支护三种不同支护型式，采用模拟开挖与坡顶均布加荷方式，进行了模拟基坑开挖和破坏性的两个阶段试验，对三种不同支护型式的土压力与桩位移、土体应力与变形、桩土共同作用及支护结构失稳破坏进行系统研究。
