摘要:
本文进行了砂质粉土层自由场地震响应的离心机振动台模型试验,研究了不同地震荷载条件下自由场的响应。研究结果表明,自由场响应与地震强度条件密切相关,地层响应加速度具体量值随入射地震波强度的增加而增大,但加速度放大系数却随地震强度的增大而减小,此外,地震强度对场地的侧向水平位移和地表沉降同样存在影响。
Abstract:
Free field response of dense soil subjected to seismic loading with different intensities were studied. The responses of ground were observed and presented in this paper. The results show that the free-field responses are closely related to the seismic intensity conditions. The exact acceleration value of ground increases with the increase of input earthquake intensity. However, for a stronger motion the amplification effect will be obscure in terms of amplification factors, which turn to be smaller, especially at ground surface.
