填海场地软弱夹层的地震响应特征分析
Seismic Response Characteristics Analysis of Weak Interlayer in Reclamation Site
摘要
Abstract
Based on the profile of a typical soft clay interlayer in the reclamation area of Qianhai Free Trade Zone in Shenzhen, the influence of the thickness and depth of the weak interlayer on the ground motion characteristics is analyzed. 35 soil layers were constructed according to the thickness and depth of the weak interlayer, where the thickness is divided into 2 m, 4 m, 6 m, 8 m, 10 m, and the buried depth is dividedinto 0 m (surface), 5 m, 10 m, 15 m, 20 m, 30 m, 45 m (bottom) . Based on seismic response analysis ofthe above 35 soil model with different transcendental probability ground motion using soil one -dimensionalequivalent linearization method, the results show that when the input ground motion is constant, with theincrease of the depth of the weak interlayer, the ground acceleration peak magnification k decreases gradually,and when the buried depth exceeds a certain depth, the k value is less than 1; with the increase of thethickness of the weak interlayer, the peak acceleration magnification k increased significantly and thendecreases; with the increase of input ground motion, the magnification k decreases in each case, and the peakvalue of ground acceleration decreases obviously.关键词
