摘要：A large number of soft clay layers are distributed in coastal areas, which brings risks to port construction. Especially in the course of channel excavation, the construction will affect the overall stability of the outer riprap breakwater. Through numerical simulation and Geocentrifuge model test, the influence of waterway excavation on the overall anti-sliding stability of a breakwater in Tianjin harbour is studied and analyzed. The experimental results show that when the excavation boundary line is 38.9 m away from the foot of the breakwater and the excavation depth is 10 m, the overall anti-sliding stability of the breakwater is less affected. The vertical displacement of the top of the breakwater is 6 mm, and the horizontal displacement of the foot of the breakwater is 23.4 mm, all within the safety control range.
