钻孔倾斜仪累计误差的处理

钻孔倾斜仪是一种高精密度的监测仪器．在岩土监测中被广泛应用。但由于累计误差的原因，使其提供的累计变形量与被测体的真实变形有较大的差距，特别是在短期监测成果中，其结论有可能与事实相悖．通过对观测资料的统计分析，找出了产生误差的一般规律。经处理后的结果可较为真实地反映被测体的变形情况，从而可扩展钻孔倾斜仪的使用条件．将监测成果量化，使其更接近实际情况。

Cumulative Error Correction for Borehole Inclinometer

Borehole inclinometer is a kind of high precision monitoring instrument and is widely used in geotechnical observation . However , due to cumulative error , the cumulative deformation values differ greatly from actual deformation values ,especially in short time observation results which are not in agreement with the facts . General rule for producing error is found by statistical analysis on observation data . The corrected results will actually reflect rock deformation condition . Consequently, application condition for borehole inclinometer can be enlarged and observation results are quantified to be close to practical situation .
