| Abstract: | The excavating in deep foundation pit induces the groundwater level difference inside and outside the foundation pit and the groundwater leakage around the bottom of the retaining wall,which affect the water and earth pressure distribution on retaining wall.Calculation methods for water and earth pressure on retaining wall have been summarized.Aiming at the excavation with layered soil,the traditional methods for the separate calculating and integral calculating of water and earth pressures are analyzed,and... |
