According to by the time series estimate power spectral density\'s periodogram law principle,the research adopts five level of orbital power spectra which US Federal railway Administrative bureau FRA proposed;then,through the Fourier inverse transformation,the orbital not smooth time domain samples are obtained, which determine the track irregularity peak-to-peak value and the corresponding wave length; on the basis of the research,the influence of the wheel track dynamic contact force are considered.Based on the orbital roadbed coefficient\'s definition,computation model is established to solve the roadbed equispaced spring constant,and the roadbed uniform spring stiffness is obtained by using the numerical simulation method.Finally,based on the Matlab procedure platform,the computational procedure is established,and the load time interval caused by the moving train acts on the roadbed is obtained.

繁殖可利用播种法。扦插法及切根法繁殖，播种发芽适温为20-25℃左右，春。夏。秋均可，播种后约1个月左右发芽，播种法虽然可以短时间获得较多的植株数量，但是从播种到开花的时间较长，所以一般还是多以扦插繁殖为主，扦插以春。夏两季为适期，以顶芽插为佳，扦插极轻易发根，扦插后约4周即可成苗。
