It was indicated by the existing researches that the principalstressratio in the stress path of rockfill DAMS kept constant during the period of dam construction.
已有研究表明，土石坝内堆石料在填筑期的应力路径可近似为等应力比的路径。

The experimental results show that the failure of specimens will be either hydraulic fracturing or shearing plastic flow, it depends on the initial principalstressratio.
研究结果表明，在不同起始主应力比条件下，试件可以表现为水力劈裂破坏，也可以为剪切塑流破坏。

When the dry density is relatively high, this dense specimen shows shear dilatation characteristics, and the effective principalstressratio tends to be strain softening phenomenon.
