海中取淤的海堤安全距离分析
Safe Distance to Sea Wall for Dredging in the Sea
摘要
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 10 mm, relax the limit of displacement could get closer distance.关键词
