| 中文摘要: |
| 盖重压渗是深厚型冲积地基堤防的主要渗流控制措施。通过研究地基弱透水表层与透水层的渗流交换研究渗透扬压力与盖重土层有效重力的平衡关系，建立了普遍适应性的堤防盖重压渗计算模型，采用VB6.0语言编制了可视化操作界面并开发了计算机绘图功能，研制出方便快捷的堤防盖重压渗设计系统。通过实际应用证明，其渗流计算结果与有限元计算结果十分接近。 |
| 英文摘要: |
| The weighting soil layer constructed at downstream toe of dike built on thick alluvial foundation is an effective measure for preventing the foundation from blowout failure. According to the principle of equilibrium between seepage uplift and effective overburden pressure of weighting soil layer, a mathematical model for seepage analysis of dike is established. By using this model a CAD system for the design of weighting soil layer is developed. In the system the visual operation interface is programmed by VB6.0. |
