| 摘 要： | 在距离海堤较近的海中取淤会引起海堤较大的变形。针对某围海造地工程,选择常规的斜坡堤进行分析。采用理想弹塑性模型,改变取淤位置与堤脚的距离进行计算。结果表明如果以10 mm为控制标准,取淤距离保持300 m是比较合适的。放松对位移的要求,取淤距离可以更近一些。 |

| Abstract: | For taking deposition from sea for land reclamation,if the dredging spot is close to the sea wall,it may lead to large deformation and even imperil the wall.But large distance may increase the construction cost.In this paper,a sloped dike is analyzed in view of a land reclamation project.Using the ideal elastoplastic model,the deformation of sea wall with different distance from the dredging spot are calculated.It is found that distance of 300 m is favorable to make the displacement of the dike in less than... |
