摘要/Abstract

摘要： 基于近断层速度脉冲与相位差谱的统计规律,提出一种脉冲型地震动人工合成方法,该方法能够确保合成地震波时域与频域的非平稳性。在此基础上,依托巴基斯坦N-J水电站,采用数值仿真方法研究方向性效应速度脉冲对引水隧洞的影响。结果表明:低频速度脉冲更接近围岩的自振频率,能够显著提高衬砌的内力,具有较强的破坏性。在近断层隧洞等地下工程的抗震设计中需要考虑断层的速度脉冲分量。

Abstract: Based on the statistical characteristics of the velocity pulse near the fault and the phase difference, a synthetic method of pulse-like ground motion was proposed. This method could ensure that the synthetic record was non-stationary both in time domain and frequency domain. Based on the N-J hydropower station in Pakistan, the effect of the velocity pulse on the seismic responses of the tunnel were studied by numerical simulation. The results showed that the seismic response of the tunnel was significantly influenced by the velocity pulse. When considering the velocity pulse, the internal forces in tunnel liner increased remarkably, and the damage to the tunnel liner became more serious. The velocity pulse should be considered in anti-seismic design for the tunnels near the faults.

Key words: velocity pulse, tunnel, seismic response, fault
