| 摘 要： | 根据洞庭湖区堤基地质特点,建立了多元结构堤基的堤内压盖模型,并采用渗流有限元法,通过改变堤内压盖宽度或厚度,进行优化研究.提出堤内压盖的临界宽度、厚度概念,并将有限元计算的临界宽度、厚度与堤防设计规范中压盖公式计算的结果进行对比,两者一致,说明有限元法处理压盖问题正确可行.最后,将有限元法应用到洞庭湖区资江大堤柴山湖段压盖处理工程中,结果表明,该方法对于求解实际复杂工程问题实用有效. |

| Abstract: | According to the characteristics of geology of the levee foundation in Dongting Lake region,covering soil layer model in multi-structure levee foundation has been established;through changing the width or thickness of covering soil layer,optimization study is carried out by seepage FEM.The concepts of optimization of width and thickness of the covering soil layer inside levee are put forward;and then the results of FEM and the covering soil layer formula in Code for Design of Levee are compared.The comparison shows that the both are coincident;and FEM is an effective tool to solve the covering soil layer problem.Finally,FEM is applied to Chaishanhu section of the Zijiang River levee;and it is shown that FEM is practical and effective for the real complicated projects. |
