Fundamental behavior and constitutive modeling of a cdg residual soil under undrained shear 不排水条件下全风化花岗岩残积土工程特性与本构模型
Serial and parallel stress - strain relations in saturated soils have been theoretically deduced from un - drained stress - strain relations with a new condition of frame volume deformation equaling to total volume deformation , which were suggested for the first time in this thesis and proved a theoretical method to choose suitable mechanical models ( 4 )论证了了土动力学中串联与并联的力学模式是不排水条件下应力-应变关系的两个特例,从应力-应变关系上统一了串联与并联的力学模式,不排水条件下,应力-应变关系有一新的重要的结论是:骨架的体积应变等于总的体积应变。
In spite of modifying coefficient , a modifying term is used to modify brandt ' s theory of sphere grain model ; this term ' s expression has been acquired , and the result is identical to biot - geertsma ' s theory in form and quantity , in which the two classics theories is in perfect harmony . it is also confirmed that the constitutive relation of carroll and n . katsube theory , and the bulk modulu of kuster scattered waves are identical to biot theory 在工程中的绝大多数情况下,该结果与biot - geertsma理论的结果在形式及数值上几乎完全一致,从而使这两个不直接相关的经典理论较好的统一起来。 ( 3 )在土动力学中常用的不排水条件下,分别证明了carroll的应力-应变关系中不排水体积模量、 kuster散射波理论的体积模量与biot - geertsma理论是完全一致的。
