Analysis on Foundation Excavation Side Slope Stability and Over-Break Depth of Embedded Pile Cap in HZM Bridge

Abstract

In the paper, relying on the full-scale model test of embedded pile cap of the HZM Bridge, the method of combining the theoretical calculation analysis and in-situ monitoring test are used to study the slope stability and over-break depth of foundation excavation. In the theoretical calculation analysis, an empirical formula of the Hydtology of Sea-port is adopted for the over-break depth while the G-slope software is for the safety factor of slope stability; in the in-situ monitoring test, the single-beam is used for the topographic survey underwater at random after the foundation excavation. Analysising on the theoretical calculation analysis and the result of in-situ monitoring test, proper slope ratio and over-break depth of pile cap foundation excavation is put forward to provide key construction parameters for the main project of the HZM Bridge.
