摘要:
前人对高山峡谷地貌区高位斜坡动响应研究较多,但对低山、丘陵地貌区斜坡强震动响应研究很少。并且,研究这类地区顺倾斜坡的地震动响应对揭示长宁Ms 6.0级地震丰富的次生山地灾害动力机理具有一定意义。在四川省长宁县丘陵地貌区典型顺倾斜坡不同部位安置强震监测仪器,捕捉到40多次余震,通过SeismoSignal软件处理典型余震数据,分析峰值加速度、阿里亚斯强度、傅里叶频谱、加速度反应谱,进而采用水平/竖直向谱比法分析局部场地效应,最后对比分析低山、丘陵地貌区与高山峡谷地貌区的斜坡动响应。结果表明:坡顶峰值加速度可达4.171 m·s-2,最大位移可达0.008 05 m,当峰值加速度大于1.0 m·s-2时,阿里亚斯强度出现陡增的趋势; 局部地形的放大效应使得地质灾害以沿山脊的裂缝及小型崩塌为主,在低频2~5 Hz处,斜坡中上部易发生山体共振。以上研究揭示了砂、页岩顺倾斜坡高位放大效应,为地震山地灾害易发性区划提供地震监测资料。
Abstract:
There are many studies on seismic response of high slope in deep-cut valley morphologic area, but the research is rarely found in hilly morphologic area. It is of great significance to study seismic response of the inclined slope in this area to reveal the dynamic mechanism of abundant secondary mountain disasters caused by Changning Ms 6.0 earthquake. The strong earthquake instrument was placed in different parts of the typical slope in hilly morphologic area of Changning county, Sichuan province, and more than 40 aftershocks were captured. The data of typical aftershocks were processed by SeismoSignal software to analyse the peak acceleration, Arias intensity, Fourier spectrum and acceleration response spectrum, then the local site effect was analysed by horizontal/vertical spectrum ratio(HVSR)method. Finally, the seismic response of slopes in hilly morphologic area was compared with that in deep-cut valley morphologic area. The results show that the peak acceleration can reach 4.171 m·s-2 with the maximum displacement of 0.008 05 m at the top of slope; when the peak acceleration is greater than 1.0 m·s-2, Arias intensity increases sharply; the geological disasters caused by the local topography amplification effect mainly consist of ridges and small collapse, and mountain resonance possibly occurs in the middle and upper of slope at the low frequency of 2-5 Hz. The above researches reveal the high-amplification effect of inclined slope in sand and shale, and provide a large amount of seismic monitoring data for the susceptibility of earthquake-induced mountain disasters.
