With the increase of lateral pressure modulus, the magnitude of principal stress decreases and the direction of it is hardly changeable ; with the increase of the angle between the direction of the maximal horizontal principal stress on magnitude and the fault bearing, the magnitude of principal stress increase and its direction can hardly change ; with the increase of the elastic modulus of rocks, the magnitude of principal stress increases and the direction changes more ; with the increase of pr, the magnitude of principal stress decreases and the direction changes more ; with the increase of lateral pressure modulus, the principal stress at hance, the tress at topmost arch, bottom arch and principal stress at lateral arch decreases, with the increase of the depth of tunnel, the stress of surrounding rock also increases, and the poorer the quality of surrounding rock is, the little its principle stress is
分析得出，隨著側壓力系數的增大，主應力量值減小，主應力方位難改變；隨著與斷層走向的夾角增大，主應力量值增大，應力方向難改變：隨著巖石的彈性模量的增大，主應力量值增大，方向變化越大；隨著泊松比的增大，主應力量值減小，方位變化越大。隨著側壓力系數的增大，頂、底拱處的各應力值增大，拱腰處的主應力減小，剪應力增大，側拱處的各主應力減小，同一側壓力系數的條件下圍巖質量越差，各應力值也越小；隨著洞室埋深的增加，圍巖壓力也增大，圍巖質量越差，其應力值也減小。 -
Applying relative arithmetic to all kinds of faults and calculating off - line, we can master time - distance relation chart for all kinds of faults. computation indicates : when transmission lines occur faults, the data window of protection algorithm consisting of prefault and postfault data at the same time has important significance. the following methods are useful to achieve the inverse time characteristic : calculating impedance by using flourier in a full cycle, calculating work voltage by using fault component, calculating the torque created by a phase comparator or a magnitude comparator
實際的計算表明：輸電線路發生故障后，用故障前後的數據同時充滿保護演算法的數據窗，對于快速切除近區故障具有很重要的意義；同時利用故障前後的數據，下述方法可以比較好地實現距離保護的反時限特性：直接用全周傅里葉演算法進行阻抗計算；採用工頻變化量阻抗繼電器進行工作電壓的計算；採用轉矩的思想進行轉矩的計算。 -

Adopting this model, we analyze the seismic hazard near the chelungpu fault that generated the chi - chi ( jiji ) earthquake with magnitude 7. 6 and the following conclusions are reached. this model is reasonable on the base of focal mechanism, especially for sites near potential earthquakes with large magnitude ; the attitudes of potential rupture surfaces have great influence on the results of probabilistic seismic hazard analysis and seismic zoning
結果表明：採用潛在地震破裂面源模型是合理的，因為它可以模擬地震破裂面與地震動影響場的三維展布特徵，尤其適用於較大震級地震的近場區域；潛在地震破裂面源的大小、產狀，對近震源場點的地震危險性分析和地震區劃結果有明顯的控制影響。 -
The difference between it and traditional observer - based fault diagnosis is that producing residues and analyzing it to fault diagnosis is not its main aim. it is straightforward to build estimator to detect whether faults appear and its magnitude. for the character of the faults and the location of the faults appeared this paper proposes four corresponding techniques
該方法與傳統基於觀測器的故障診斷方法的區別在於，該觀測器的主要任務不是用來對系統產生殘差，而是直接建立故障估計器，對所監測的系統直接估計其故障的有無和大小，實現一種較為直接的故障診斷。 -
Judging by the different magnitude and direction of the wavelet packet coefficient modular maximum, we can select the single phase - to - earth line. the method using wavelet singularity detection theory to extract the fault time is discussed. a fault distance measurement algorithm combining wavelet analysis used for separating the character from the transient fault signal with artificial neural networks used for the nonlinear approximation from the transient character to fault distance is presented
論文提出利用各個出線零序電流在頻帶上小波包系數模極大值的方向和大小的不同來實現故障選線，討論了利用小波分析的奇異性來判斷故障啟動時刻，提出將小波分析和人工神經網路結合，利用人工神經網路的非線性逼近能力，實現故障暫態量到故障距離的非線性映射，完成測距。 -
