| Abstract: | On the basis of introducing local erosion formula,the erosion calculation formula of pier in existing standard in China is checked,the local erosion mechanism and erosion shape in the sinking process of steel open caisson are studied,the influence factors of local erosion are analyzed.The results show that for the erosion formula of non-viscous soil of the pier,formula 65-1 is reasonable;the influence factors for the depth of local erosion are tidal action and declination. |
