principal stress direction meaning in Chinese
枝力方向
Examples
- Principal stress direction
枝力方向 - ( 6 ) the principal stress direction arised deflexion obviously after excavation , the maximum principal stress paralled to opening , minimum principal stress vertical to sidewall or vault
( 6 )数值模拟研究表明，隧道开挖后，主应力方向发生明显偏转，最大主应力与开挖临空面平行，最小主应力近于垂直。 - Former true triaxial test research have been lack of the completely study on soil anisotropic deformation characteristic on condition that load in each of the tree principal stress direction because of their different research purpose
由于研究目的不同，以往真三轴试验研究中缺乏针对三主应力单向加荷时的土体各向异性变形特性较全面的研究。 - Secondly , true taixial test by load in three different principal stress direction for study on soil anisotropic deformation characteristic are processed . lateral deformation relative to load direction , lateral deformation relative to lateral direction and the stess - strain relationship in load direction are analyzed , and soil anisotropic deformation characteristic on the three aspects of elastic ratio , poisson " s ratio and the property of compliment matrix are completely analyzed too
其次，为揭示土体各向异性变形特性，有针对性进行了三主应力分别单向加荷的真三轴试验研究，分析相对于加荷向的侧向变形、互为侧向的侧向变形、不同主应力加荷向的应力应变关系各向异性性状。
