  1. Firstly in this part, computer simulation methodology based on the baecher model for generating network of discrete fractures was presented, which includes the follow details : probability distributions of fracture density, orientation, trace length, size, and aperture and estimation of their statistical parameters ; stochastic models of fracture network ; monte - carlo ' s simulation method ; numerical simulation procedure and technicality. then, boundary element method was used to calculate flow through the generated fractured network. assuming single fracture as a two - dimension inexpressible isotropic porous media, boundary element method equations for flow in single fracture and then in fracture network were derived using the weighted residual method

  2. According to the representation of the heterogeneity, mathematical models for predicting flow in fractured geological media fall into one of three broad classes : equivalent continuum models, discrete fracture network simulation models and hybrid techniques

    根據對這種非均質性的不同處理方法,對裂隙巖體中的滲流進行預測的數學模型通常可以分為三種:等效連續體模型,離散裂隙網路模型和混合模型。
  3. In the paper each mathematic model of seepage in fractured rock masses is summarized. finite element analysis simulation equations of non - double porosity system model - equivalent continuum media model and discrete fracture network model are given, furthermore a coupling uniform model is formed which integrated with the merit of the two former models

    本文綜述了裂隙巖體滲流分析的各類數學模型,對于非雙重介質模型? ?等效連續介質模型和離散裂隙網路模型分別給出了它們的有限元模擬公式,還進一步提出了結合上述兩種模型優點的適用於復雜裂隙巖體的耦合統一模型。
  4. By studying the discrete fourier transform properties of the band - limited digital signal, the authors introduce alternating projection neural networks into the paper, expand apnn ' s application scope from real field to complex field, and present several important conclusions on apnn. analyzing and discussing network ' s tolerance to noise, convergence rate and the spectral leakage problem of the truncated signal expected to be extrapolated by using these conclusions, the paper presents an extrapolation algorithm for band - limited signals based on alternating projection neural networks. a lot of simulation experiments show that the algorithm is effective. in addition, the algorithm is also effective to spectrum extrapolation. owing to adopting network structure, the algorithm is prone to parallel computation and vlsi design, and consequently can satisfy real time military processing needs

    本文通過對頻帶受限數字信號的離散傅立葉變換特性的研究,引進了交替投影神經網路,並將其應用范圍從實數域拓廣到復數域,且給出了在復數域仍然成立的若干結論.運用這些結論,在對網路噪聲抑制、網路收斂速度及待外推信號因截斷而造成頻譜嚴重外泄問題的分析與討論的基礎上,提出了一種基於交替投影神經網路的外推演算法.模擬實驗表明該方法是行之有效的.另外,該演算法對頻譜外推同樣適用;由於它採用全互連神經網路結構,易於并行計算和vlsi實現,從而可滿足軍事上實時處理的需要
