Transmitting Characteristics of Seismic Motion in Super-Deep Overburden Layer Ground

Figure 6

Comparison of the vibration acceleration time history and the corresponding acceleration spectra (damping ratio is 0.05) of soil layers at different altitude in the ground. (a) Inputting seismic motion (surface of the rock outcrop). (b) Surface of the bedrock under overburden layer ground (the height to bedrock surface is 0 m). (c) Surface of layer ① (the height to bedrock surface is 241 m). (d) Surface of layer ② (the height to bedrock surface is 334 m). (e) Surface of layer ③-1 (the height to bedrock surface is 481 m). (f) Surface of layer ③-2 (the height to bedrock surface is 495 m). (g) Surface of layer ③-3 (the height to bedrock surface is 546 m). (h) Surface of layer ④ (the height to bedrock surface is 566.9 m).
