作者在总结磨黑6.8级地震详细震害调查资料的基础上,将震区穿斗木构架房的柱脚移动和架体歪斜方向加以统计分析,勾绘出位移方向图和无柱脚移动的区界。另外还扼要地叙述了边坡裂缝所反映的地面运动问题。作者将考察获得的等震线图、地表破坏等值线图、柱脚位移零值线图加以对比,指出这些资料从不同角度反映了震区地面运动状况,说明这次地震的发震构造作顺时针走滑运动。
On the basis of summarizing the investigation data of the detailed earthquake damage of MS 6.8 MSW earthquake, the author analyzes the displacement of the column foot and the skew direction of the framed timber house in the earthquake area, and draws the displacement pattern and the non-moving column District boundaries. In addition, a brief description of the ground motion reflected by the cracks in the slope is provided. The authors compare the obtained iso-isograms, surface contours contour maps and zero-displacement line diagrams of column-foot displacements, and point out that these data reflect the ground motion of the earthquake area from different angles and illustrate the seismogenic structure of the earthquake Clockwise slippery exercise.
