摘要
沿海地区建设的离岸人工岛,岛内设河道以兼顾亲水景观和环境保护。外海水位周期性变化频繁属非稳定渗流问题。本文基于逐步积分法,研究结果得到了非稳定渗流场分布、渗流损失水量,并模拟了防渗工况下的防渗效果,对提高人工岛的设计合理性及工程安全性具有实际意义。
The watercourses inside of the artificial offshore islands constructed along the coastal areas can play the roles of both the water accessibility landscape and environment protection. The cyclical fluctuation of the seawater level outside of the island is frequent and belongs to an unsteady seepage problem. Based on the step-by-step integration method, the unsteady seepage field and the water amount from the seepage loss are studied herein, and then the anti-seepage effect under the anti-seepage condition is simulated as well. The study result has a practical significance for improving the design rationality and engineering safety of the artificial island.
