虎跳峡梯级电站是金沙江中下游河段梯级开发的“龙头”，除其自身具有巨大的效益之外，对下游各梯级也将产生很大的补偿调节作用。研究认为，该河段地形地质条件复杂，处于Ⅷ～Ⅸ度地震烈度区，区域及近场活动断裂发育；各拟选坝址多存在高陡边坡问题，同时也不能完全排除水库及岩溶渗漏的可能性，河床深覆盖层的存在将使坝基防渗处理十分困难。峡谷左岸存在两家人及核桃园两巨型崩滑体，就目前所掌握的资料来看，两崩滑体特别是核桃园崩滑体整体稳定性较好，但下峡口水库蓄水后，仍不能排除存在局部失稳的可能性。峡谷左岸引水隧洞及地下厂房施工将可能遇到的复杂高地应力及边坡稳定问题也是应进一步研究的重要内容。
The Hujiao Gorge cascade hydropower station is the “leader” of the cascade development of the middle and lower reaches of the Jinsha River. In addition to its huge benefits, it will also have a great compensatory effect on the downstream cascades. The study shows that the topography and geology condition of this reach is complex and is located in the Ⅷ ~ Ⅸ seismic intensity region, with the development of regional and near-field active faults. There are many high-steep slope problems in the selected dam sites, and the reservoir and karst seepage can not be completely ruled out The possibility of leakage and the presence of deep overburden in the riverbed will make dam foundation seepage control difficult. Two families exist on the left bank of the Canyon and two giant collapse bodies in Walnut Park. According to the information available at present, the stability of the two landslides, especially the Walnut landslide body, is good. However, Can not rule out the possibility of local instability. The complicated high ground stress and slope stability problems that may be encountered in the construction of the left bank diversion tunnel and underground powerhouse of the left bank of the Canyon are also important contents for further study.
