| 摘 要： | 超浅层小半径曲线顶管工程中,地面扰动成为施工过程中必须关注的问题。以杭州半山超浅层曲线顶管工程为基础,利用大型通用有限元软件ANSYS对超浅层顶管的施工过程进行数值模拟,建立超浅层小半径曲线顶管模型,对模型实施不同的顶进速度,用以进一步探求超浅层小半径曲线顶管在不同顶推速度下的地面变形规律,提出顶进速度建议值。 |
| 关 键 词： | 超浅层小半径曲线顶管 地面变形 顶进速度 |

| Abstract: | During the construction process of the extra-shallow-underground-pipe jacking with short-radius curve,the problem of the ground disturbance must be paid attention to.Based on the pipe jacking project of Hangzhou Banshan,the construction process of extra-shallow-underground-pipe jacking with short-radius curve is simulated numerically through the large scale FEM software ANSYS.And the model of extra-shallow-underground-pipe jacking with short-radius curve is established.Different jacking speed is carried out... |
| Keywords: | extra-shallow-underground-pipe jacking with short-radius curve ground deformation jacking speed |
