At present, all the P-Y curve methods recommended by the referring code demand using geotechnic parameters C_u (three-axle undrained shear strength) and ε_50(the strain value that is equal to a half of the difference stress in the undrained triaxial compressing test). Moreover, we must do the complex and expensive triaxial geotechnic experiment to get those two geotechnic parameters, so they restrain the P-Y curve method from using comprehensively.

但目前国内外有关规范推荐的P-Y曲线均需用到土工参数C_u和ε_(50)(三轴不排水压缩试验中最大主应力差一半时的应变值)，而获得这两个参数需要进行比较复杂且费用较高的土工三轴试验，限制了P-Y曲线法的广泛应用。

The horizontal and vertical first derivatives of magnetic anomalies of an infinite cylinder are calculated by the cosine transform method, in which the maximum errors are -028 nT/m and 047nT/m, respectively and the percent errors are generally within -357%～327% and -194%～188%, respectively except several data of the boundary and part are bigger because of remains of Gibbus effect.
