The physical and strength properties of the filler material, slope topography, and rainfall intensity are crucial factors for determining the support structure stability. In this study, we investigate the deformation characteristics (pile foundation settlement, pile body bending, and pile-plate wall cracking) of the support structures in a high-filled loess slope in the Lingbao Basin using traditional in situ surveys and the IBIS-L topographic micro-deformation monitoring system, the latter of which allows continuous, uninterrupted monitoring. The collected data are analyzed and electromagnetic wave reflection intensity contour plots and monitoring point displacement curves are obtained. The support structure deformation shows notable regional differences, and the maximum deformation over the final 15 days was approximately 26.6 mm. The deformation-time curve shows a wavy-shaped increase but does not converge. The wavy pattern also indicates that the deformation of the support structure is not caused by a single factor and is subjected to external forces. The theoretical calculation results agree with the temperature monitoring data and an explanation for the wavy-shaped increase in the deformation-time curve is revealed. The deformation of mass concrete under fluctuating atmospheric temperature conditions is concluded to show a characteristic hysteresis response. [ABSTRACT FROM AUTHOR]
