In this study, the model experiment of loess filling slope instability under different compactness is carried out. Based on the indoor rainfall simulation system, combined with sensor monitoring and three-dimensional laser scanning technology, the deformation and failure process, instability mode and sliding mechanism of loess filling slope under different compactness are carried out.
The soil samples in this study are taken from the fresh section of Ansai Nangou in Yan'an City. The buried depth below the top of Malan loess is 3M, which is remolded loess.
After the soil samples are collected, the routine test shall be carried out in strict accordance with the standard for geotechnical test methods (gbt50123-2019), and then the slope filling shall be carried out according to the technical scheme. The filling quality of the slope shall be controlled by the quality of the compacted fill (GB50007-2002). After the model filling is completed, the indoor rainfall test shall be carried out. The test instrument consists of rainfall system, acquisition system, monitoring system and model box. Finally, the test data are plotted and analyzed.
The operation specifications meet the standards, and the data obtained are true and reliable.
