The key points of this paper can be concluding as follows : 1. the regulations of vibration attenuation of a subway are concluded by analyzing the situ data. in the zone near rail, the high - frequency vibration is stronger than other weight, and in the zone far away from railway, the results is opposite
主要研究內容和結果如下: 1 .對某地鐵線路環境振動實測數據進行了分析，得到了振動波在土中的傳播規律:地鐵運營誘發振動傳播過程中，近軌區域以高頻振動為主，遠軌區域以低頻振動為主。 -
By driving expressions and using the method in numerical integration, the results of numerical calculations are analyzed, discussed and contrasted with different conditions, and they showed that there are evident differences in the mean attenuation, scattering, and back scattering cross sections of oblate spheroid particles when the variance is so small that it is near to zero namely it is the same as the rotatory axes are parallel with one direction and when h - polarized and v - polarized incident waves happened. these differences are depended on the relative differences in the average orientation of rotatory axes and the polarized directions of incident wave
通過公式推導和數值積分計算並對結果做了討論和分析，對比各種情況表明：扁橢球粒子群在方差很小接近為0時，與粒子群旋轉軸一致取向的情況相同，入射波水平極化和垂直極化時的平均衰減截面、平均散射截面、平均後向散射截面有明顯的不同，這決定於旋轉軸平均取向和入射波極化方向的相對差異。
