凤翔县先秦陵区一号大墓发掘清理过程中,发现了椁木抛塌等遗迹。秦公一号大墓椁室分主椁和侧椁两部分。主椁室以上的椁木因受强大的剪切作用,抛塌现象严重,使其西半部北侧约半米见方的椁木以西北角为旋转轴,顺时钟抛开,且越是下部的椁木向南扭动的角度越大,椁木在一个倾斜面上呈现了扇状撒开之势;椁底部分的椁木有水平错位和局部倾斜变形。侧椁室本身和侧椁与主椁的联通部位,坍塌现象都相当严重。在已经揭露的四周土层剖面上,虽未见主破裂带,但北偏西约70度走向的一组断面擦痕发育,原生地层扰动明显。我们认为,这些现象属于快速抛塌所致。
Fengxiang Xian Qinling Tomb excavation process, discovered albino ruins and other relics. Qin Gong on the 1st of the main tomb 分 main points and lateral 椁 two parts. Due to the strong shearing action of Alnus crest above the main house, the phenomenon of tumbling is so serious that the Alnus cremastoidum, about half a meter on the north side of the west half, turns clockwise with the northwest corner as its axis of rotation and the lower part The greater the angle of alder twisting to the south, the alder presents a fan-like spreading tendency on an inclined surface; the alder at the bottom of the alder has horizontal dislocation and local oblique deformation. Collapsing room itself and the side and main 椁 Unicom parts, collapsed phenomenon is quite serious. Although the main rupture zone has not been found in the four-layer soil profile that has been uncovered, a set of cross-section scratches developed about 70 degrees north-northwest of China developed with obvious disturbance in the primary formation. In our opinion, these phenomena are caused by the rapid collapse.
