A Simplified Procedure for Base Sliding Evaluation of Concrete Gravity Dams under Seismic Action

Table 10

Existing dams: values of 𝛽 for each dam type evaluated with the spectral acceleration of Table 8 with reference to SLV, SLC, for granite (case of normal flood and case with 𝐿_𝑤/𝐿=0.85).

Dam tag	Rock type	normal flood		𝐿𝑤/𝐿=0.85
		SLV𝛽	SLC 𝛽	SLV 𝛽	SLC 𝛽
2	granite	0.53	0.43	>1	0.83
3		0.50	0.36	>1	0.77
4		0.36	0.26	0.8	0.6
