| 摘 要： | 从渗流场形成的机理出发,采用三维八节点等参数有限元法进行稳定渗流场计算具有高效、精确的特点.而且,反演计算要选择单元节点而不选单元内部的点进行,边界条件应按实际情况来定,计算误差用分级约束技术来控制.反演结果与物探检测结果进行了对比,综合全面地了解到库区的渗漏情况,提出了合理的控渗措施.

| Abstract: | After some calculations and their consistent with geo-exploration measurement on trials,the authors made an effective mathematic calculation model,the finite element method of three dimensional eight-node cell with equal parameter,based on the forming mechanism of seepage field. The calculation must be carried out at nodes other than inside cells. Boundary conditions are decided according to worksite. Errors are controlled by the technique of grading constraints. Leak finding with geophysical survey is compared with the inversion calculation result. The solution of the method indicates the places of seepage water measured in each case. The disposal of the dam is provided with a lot of reasonable basic data. |
