Measure deep horizontal displacement, distributed by depth 测量深部水平位移沿深度的分布

How a Sliding Inclinometer Works滑动式测斜仪如何工作
The casing is permanently installed in a vertical borehole through the zone of expected movement, with its bottom keyed into a stable stratum as the datum. The probe's gravity-referenced MEMS accelerometer reads the inclination θ at every 0.5 m step; summing each segment's horizontal component from the bottom up rebuilds the full displacement profile. 测斜管永久埋设在穿越待测位移区域的垂直钻孔内,底端嵌入稳定地层作为基准。探头内以重力为基准的 MEMS 加速度计每 0.5 米读取一次倾角 θ,将各段水平分量自孔底向上累加,即可重建完整的位移分布曲线。
- 1Pass 1 — A0 direction第一遍:A0 方向
The A-axis positive guide wheels run in the A0 groove; reading bottom-up at every 0.5 m records RA0 = sin θ + b, where b is the sensor's zero offset — from residual assembly stress, circuit bias and temperature drift.A 轴正方向导轮滑入 A0 导槽,自孔底向上每 0.5 米记录 RA0 = sinθ + b。b 为传感器零位偏置,来自机械装配残余应力、电路偏置电压与温度漂移。
- 2Pass 2 — rotate 180°第二遍:旋转 180°
The probe is withdrawn, rotated 180° about its axis so the same wheels run in the A180 groove, and the survey is repeated: RA180 = −sin θ + b.将探头抽出,沿中轴线旋转 180°,同一组导轮改入 A180 导槽,再从孔底向上测一遍:RA180 = −sinθ + b。
- −Subtraction cancels the zero offset相减:消除零位偏置
(RA0 − RA180) / 2 = the true sin θ — the zero offset b cancels exactly. That is why both passes are mandatory on the first, baseline survey: a missed reverse pass locks the drift into every later result.(RA0 − RA180) / 2 即真实 sinθ——零位 b 被完全抵消。这正是首测(基准)必须双向反测的原因:漏测反向系列,漂移将被永久带入后续所有数据。
- +Addition yields the checksum相加:得到校验和
RA0 + RA180 = 2b ≈ 0. The checksum distribution is reviewed before data is delivered: |checksum| < 0.5 mm/m passes; values persistently above the threshold flag instrument zero drift — recalibrate the probe rather than trust the curve.RA0 + RA180 = 2b ≈ 0。交付数据前先审校验和分布:|校验和| < 0.5 mm/m 为合格;持续超阈值说明仪器零位漂移——应送检校准,而不是继续相信曲线。
Curves You Can Act On可直接决策的曲线
After each survey the app jumps straight to plots and data: the casing profile, change versus the baseline and the previous survey, and the checksum distribution — all reviewed on site before the data ships to the cloud. 每次测量完成后,App 自动跳转至"绘图和数据"界面:管形图、相对首次/上次的变化曲线与校验和分布——全部在现场审完再同步上云。
- ✓Casing profile管形图
Cumulative offset (mm) against depth (m). First check: is the overall shape smooth, with no sudden jumps? A jump usually means a depth was recorded wrongly — check the cable depth markings.横轴累计偏移量(mm)、纵轴深度(m)。先看整体管形是否平滑、有无突跳——突跳通常意味着深度记录有误,应核对电缆深度标识。
- ✓Cumulative & incremental change累计与单次变化曲线
Offset change relative to the first survey reveals displacement trends; change versus the previous survey shows the short-term rate. Overlaying successive surveys shows whether movement is still growing — the key call for early warning, and a way to locate the sliding surface.相对首次测量的变化反映位移趋势,相对上次测量的变化反映短期速率。多期曲线按时间叠加,可判断位移是否仍在持续增大——这是预警的关键判断,也可据此反演滑动面位置。
- ✓Checksum distribution校验和分布
Checksum (mm/m) against depth. Before any report is delivered the whole hole should sit within ±0.5 mm/m — the checksum identifies instrument anomalies before they contaminate the displacement record.横轴校验和(mm/m)、纵轴深度。报告交付前,全孔应处于 ±0.5 mm/m 以内——校验和在仪器异常污染位移数据之前就将其识别出来。
