Abstract

In response to the insufficient theoretical basis for accuracy measurement in the layout scheme of measuring points in the existing fixed inclination sensor method for measuring deep horizontal displacement of foundation pits, this paper introduced an analysis method for the segmentation error and measurement angle error of inclination sensor measurement deformation, and obtained the measurement point layout laws of the fixed inclination sensors that meet certain measurement accuracy. Comparative experiments in the laboratory show that the error between the deep horizontal displacement measured by the fixed inclination sensor installed by adopting the described method in this paper and the actual displacement can meet the requirements of engineering measurement accuracy. The error analysis method and the arrangement of measuring points can provide theoretical basis for the measurement of deep horizontal displacement of foundation pits by employing fixed inclination sensors.
