| 摘 要： | 沿斜溪场地乡村公路布设4个水准测点，其中2个点高差在1997~2015年趋势下降，之后趋势上升。研究斜溪断裂性质认为，断层上盘在2015年前后由下沉转为上浮，经异常核实为机砖厂影响所致。为解释场地沉浮现象，采用粘弹性介质模型，利用跨断层短水准观测资料和最小二乘方法计算介质的延滞时间为32个月。

| Abstract: | Four leveling points of Xiexi site are laid along the rural highway, of which two are measured. The trend of point height difference decreases from 1997 until 2015, when the turning trend increases. According to the properties of the Xiexi fault, it is shown that the upper wall of the fault moved from sinking to floating before and after 2015, and the abnormality is verified to be environmental interference caused by the brick factory. To explain this phenomenon, the viscoelastic medium model is used and the delay time is calculated by using crossing-fault short-leveling observation data and the least square method. The results are 32 months. |
