The influences of principal stress axes rotation.

主应力轴旋转对岩土工程的影响日益受到人们的重视。

In many practical geotechnical problems,soils are always subjected to the stress path involving the principal stress rotation.

试验表明:土体强度主要受原生各向异性影响,试样在破坏时的主应力作用方向以及中主应力参数是影响土体强度的主要因素,而主应力轴旋转对于强度则无显著影响;试样无论是否经历主应力轴旋转,在破坏时都会有显著的剪切带产生,同时剪切带平面与大主应力作用方向的夹角基本保持一个常数;主应力轴旋转会引起土中孔压积累,积累程度受主应力轴转幅及旋转时剪应力幅值、剪应力水平支配。

The experiments used to detect the characteristics of soil under the condition of principal stress rotation are analyzed systematically.

对目前国内外主应力轴旋转条件(包括单向旋转和循环旋转)下土体性状研究的室内试验进行系统的分析与总结,得到以下结论:土体在不排水主应力轴旋转条件下产生孔压积累,这在主应力轴循环旋转中特别显著,且通常大于等剪应力幅度的动三轴或扭剪试验产生的孔压,并可建立与某种应变增量的函数关系,此外孔压开展的速率与程度受到土体原生各向异性的影响,但当试样所受剪应力水平较低时,上述影响的程度减弱。
