Abstract

In view of the deformation of sheet piles and the pile-soil interaction mechanism of revetment slopes during channel excavation, the key physical parameters such as displacement of sheet piles, earth pressure and deformation of the adjacent soils are monitored by selecting typical sections for the field tests. Combined with the theoretical calculation, the stability of the sheet piles and the bank slope is analyzed, and the interaction mechanism between the soil deformation behind the piles and the active earth pressure with complex geological conditions is explored, and some useful conclusions are drawn. The horizontal displacement of the soils behind the sheet piles increases gradually with the excavation. When the slope reaches stability, the soil displacement at different depths is about 0.8~1 mm, and the horizontal displacement at the top of the sheet piles is about 1.2 mm. During channel excavation, the active earth pressure of the sheet piles gradually decreases with the excavation, and the reduction value of the earth pressure at pile side at different depths is about 1 kPa. Compared with the theoretical results, the field test results are small, indicating that the theoretical calculation is slightly conservative for the field tests. The conclusion can provide a useful reference for the revision of the existing related specifications for the sheet piles.
