| 摘 要： | 以北京平原区地震钻孔为基础资料,建立三维剪切波速速度模型,获得了2个代表性的波速剖面,研究其与地质构造和隐伏断裂之间的关系,结果表明：北京平原区新构造运动和隐伏断裂活动对晚第四纪地层沉积和发育具有控制作用,而且浅层剪切波速的差异性也为隐伏构造的位置确定提供了帮助。

| Abstract: | In this paper, we use drill logging to obtain a shallow 3-D shear wave velocity structure model, and select 2 typical velocity profiles to explain the relationship between the structure and buried fault. The results show that the late quaternary Sedimentary in Beijing plain are controlled by the new tectonic and buried fault movement. Moreover, the difference of shear wave velocity plays an important role in the precise positioning of the buried structure. |
