( 3 ) we can detection the azimuth of crack growth by abnormal amplitude or the discrepancy of wave - speed. ( 4 ) we can guess whether crack contains fluids by the change of p - wave speed. second, using pore model, under press and temperature, we have studied the influences of pore density on the characteristic parameters of seismic wave
第一、利用人工裂縫模型,研究了裂縫密度、方位和張開度的變化對地震波屬性參數的影響,根據實驗結果,總結出:可利用橫波分裂的不同程度來檢測裂縫密度的高低;可利用縱橫波的振幅、主頻、衰減(或品質因子q )和主振幅的變化來檢測裂縫張開度的變化;可利用速度的差異和振幅異常來檢測裂縫發育的方向;可利用縱波速度的變化來推測裂縫中是否含流體。The explicit method is widely used for its simpleness and little memory consumed with local time step and variable coefficients implicit residual smooth to accelerate the convergence procedure. according to yoon and jameson ' s ideas, an efficient implicit lu - sgs algorithm is carefully constructed by combing the advantages of lu factorization and symmetric - gauss - seidel technique in such a way to make use the l and u operators scalar diagonal matrices, thus the numeric algorithm requires only scalar inversion. the computational efficiency is greatly improved with this scheme
顯式方法具有簡單,消耗內存小等優點,並採用當地時間步長、變系數隱式殘值光順等加速收斂措施,在定常流動的模擬中得到了廣泛的應用;根據yoon和jameson提出的簡化正、負矩陣分裂,構造的l 、 u運算元只需進行標量對角陣求逆,極大提高了流場數值求解過程的計算效率;採用newton類型的偽時間子迭代技術使時間推進精度提高至二階。
