| 摘 要： | 作为一种高精度的形变观测,钻孔倾斜观测点必须尽可能避开干扰源。河流、湖泊、仓库(货场、列车编组站)和铁路,是几种主要的影响钻孔倾斜观测的地面载荷变化干扰源。中对这些地面载荷变化干扰影响分别建立了不同的模型,提出了针对一定的干扰限定指标,估计观测点到干扰源的最小“安静”距离的方法。

| Abstract: | Being a deformation measurement with high resolution, borehole tiltmeters should be installed far away from disturbance sources as far as possible. Rivers, lakes, large warehouses and railway are some of the main sources of disturbance affecting the tilt field due to mechanical loading and unloading on the surface. In this paper, the author proposed different models for each of these disturbances, in order to estimate the shortest "quiet" distance between a borehole tilt observatory site and the disturbance sources for certain threshold. |
