Minimum Buried Depth Calculation of Steel Liner of Bored Pile in Strong Tidal Area |
| |
| Abstract: | Certain railway bridge is located in the strong tidal area of Qiantang River.Taking the No.49 pier for example,the calculation method of minimum buried depth of steel liner of bored pile is introduced.At first,three calculation models of tidal pressure are introduced.Then,minimum buried depths under these three models are obtained by simplified calculation method.Midas Civil 2006 was used to model and calculate,and then the reasonable minimum buried depth is confirmed according to specification requirement. |
