For the resistance and mountain body of Shuanghe arch dam is thin and weak, safety factor of abutmentstability is low.
双河拱坝抗力体山体单薄,坝肩的稳定安全度均比较低。

Anciently, study on dam body stress, abutmentstability and up-glide stability is rather abundant by the dam engineers, but quite few on structural stability of dam body.
以往坝工界对坝体应力研究较多,对拱座稳定和上滑失稳研究也较多,而对坝体结构稳定则少有研究。

It is indicated that the dynamic amplification of abutment rock body and dam-water-foundation interaction should be considered in the aseismatic stability analysis for high arch dam abutment.
