Abstract: In a construction of airport, highway, railway, mine and other large-scale infrastructure construction projects, a vertical fill support structure become an indispensable part with the urbanization of a loess area. However, the slope supporting structure in loess area is prone to pile foundation settlement, pile bending,and pile plate wall cracking. In order to analyze its deformation characteristics, an all-weather continuous monitoring was carried out by using IBIS-L. The point and surface data collected show the followings:1) the deformation of supporting structure showed obvious regional differences in general, the maximum deformation value of the last 15 days was 26.6 mm; 2) the displacement of object monitoring points increased in a "wavy" shape at intervals of 24 hours with no convergence trend, which may cause the overall instability of the slope; 3) taking Pix8 as an example, combined with a temperature monitoring, the theoretical calculation results agreed with the monitoring data, which revealed the reason why the s-t curve increased in wave shape. It is concluded that the deformation of mass concrete in an atmospheric temperature field has the characteristic of "lag effect".

Key words: loess, high fill slope, supporting structure, deformation, monitoring
