| 摘 要： | 结合地下工程复杂渗流场三维有限元分析的实际 ,用渗透张量模拟非均匀各向异性 ,用改进丢单元法迭代自由水面 ,用隐性的复合材料单元模拟断层 ,用隔水层模型模拟防渗帷幕 ,用以沟代井模拟排水井列。在此理论基础上编制了渗流分析的三维有限元计算程序。且用此程序成功求解了漫湾水电站二期工程地下厂房围岩的复杂渗流场 ,并在此基础上分析渗流场分布的主要影响因素的影响。结果验证了程序的合理性和实用性

| Abstract: | Combined with the reality of 3D FEM analyze of complicated seepage field of underground engineering,penetrability tensor is utilized to simulate the non-isotropy medium,improved abandon-element method is utilized to calculate the free surface,latent complex-material element is utilized to simulate the waterproof,slot instead of well curtain is utilized to simulate the drainage.Based on the above theory,3D FEM calculation program for seepage analyse is compiled.Finally this program is applied on seepage analysis of 2nd Project of Manwan Underground Plant.Based on the result,the factors influencing seepage flow area are analyzed.The result testifies the rationality and practicability of the program. |
