gravitational loading meaning in English
重力负荷
Examples
- However , it is too expensive in investment , complex in experimental techniques , difficult and dangerous in performance . in this paper to overcome these drawbacks , the similarity relations together with a new method and its principle of experiment have been developed based on the model theory of structural similarity . according to this principle , the total stress ; an be obtained as a sum of the stresses due to weight and external loading , which based on only one model experiment without any gravitational loading
最后，针对外载与自重共同作用下，传统光弹性分析法中采用离心力场模拟重力场获得自重应力的试验投资耗费大、技术复杂且难度大和不安全等严重缺点，按照结构相似的模型理论，本文提出模型外载与自重并存变动外载的光弹性分析法，导出处理这个问题具体的相似律和试验原理及方法，进行了典型实验验证，指出仅用外载作用的模型试验，即不用离心力场模拟重力场的模拟试验，就可以获得上述两种载荷共同作用下的应力分析结果。 - Abstract : based on the data obtained from field observations and deformation monitoring , this paper deals with the deformation and failure of a double - decked slope composed of soft rock strata in its lower part and hard - brittle rock strata in its upper part . it is demonstrated that the deformation of this kind of slopes is always initiated by the non - homogeneous rheological compression of the lower soft rock strata , leading to the tension fracture and toppling of the upper hard rock strata , and at last the sliding of the whole deformed body will be caused by the shear failure along the stress - concentration zone in the lower soft rock mass under the actions of the gravitational loading and infiltration water
文摘:以现场考察和变形监测资料为依据，探讨一个下部有软弱基座，上部为硬脆性坡体的“二元结构”边坡的变形破坏问题，揭示这类边坡的变形总是以下部软弱岩体的不均匀压缩流变为先导，进而引起上部硬脆性坡体的拉裂与倾倒，最终通过渗入水的作用，使下部承载状况已进一步恶化了的软弱岩体，沿剪应力集中带发生剪切破坏而导致整个变形坡体的下滑。
