The upper continental formations are high dip angle structures in Heba 1 Well.

河坝1井上部陆相地层属于高陡构造，地层倾角大，极易发生井斜。

Finally, the shear strength reduction technique is used to analyze the seismic stability of Nuo Zhadu core wall type rockfill Dam and Chang Heba core wall type rockfill Dam in FEM.

最后，采用有限元强度折减技术分析了糯扎渡心墙堆石坝及长河坝心墙堆石坝上下游坝坡的抗震稳定性。
