| 摘 要： | 通常的渗流计算中排水的模拟方法很多,诸如排水子结构法、增加渗透阻抗等。但大型地下厂房与洞室的排水非常复杂,若对每个排水孔都进行模拟就非常繁杂。利用简化方法,采用给定水头和给定流量相结合的方法可以较为方便地解决复杂排水模拟的问题。对糯扎渡地下厂房和洞室群的复杂排水和对左岸包括地下厂房与硐室进行渗流计算分析,通过多个计算方案的比较,对给定流量和给定水头模拟排水效果进行合理假定,使模拟结果得到的排水区流量和水头趋于一致,由此得到合理可靠的排水模拟效果。对模拟得到的糯扎渡左岸山体渗流场进行了分析。计算结果有助于优化工程渗控方案,同时为计算变形稳定提供合理可靠的水荷载。

| Abstract: | In the seepage control analysis, many drainage simulation methods have developed, such as drainage substructure method, expansion flow resistance method, etc. However, there are many complicated drainage needed in large underground cavities, and it is miscellaneous for simulating each drainage hole in all. This paper illustrates the simplified method with underground cavities on the left bank slope of Nuozhadu Hydro-project. Base on the reasonable premise for flux boundary and head boundary, by comparison with several schemes, accordant head and flux in the drainage location was reached. The resulted drainage effect achieved is reliable. It is helpful to optimize the seepage-control schemes, at the same time water-load is provided reliably for the evaluation of deformation and stability. |
