Considering different soil spring models for vertical fault movement and horizontal fault movement, two damage cases of pe pipeline in ji - ji earthquake have also been simulated. the large deformation of a buried pipeline under fault movement is investigated in the 4th chapter. to examine the inelastic behavior of buried pipelines, the parametric studies on pipe material property, diameter ( d ), diameter - to - thickness ratio ( d / t ), crossing angle ( ), as well as soil stiffness, have been conducted using a shell - spring fem method
對於0 p三90 」的情況，當斷層位移相對管徑還不是很大時（管子內的彎曲應變與軸向拉伸應變相差不大的情況） ，斷層附近管子變形形式與梁相似；當斷層位移相對管徑很大時（管子以軸向拉伸應變為主的情況） ，斷層附近的管子軸線變形為一圓弧，管子表現得像一條沒有彎曲剛度的索。 -
A. for annealed drawn tubes the ratio of outer diameter to thickness is no more than 15
退火態拉制管外徑與壁厚之比不小於15者。 -
Based on the characterization results, the as - prepared graphite nanosheets were found to be roughly circular platelets of about 50 nm in thickness and 12 urn in diameter, exhibiting a mean aspect ratio in the range of 150 - 300
基於多種表徵技術，測試結果表明所制得的納米石墨近似於厚度在50nm左右，直徑約為12 m的圓形薄片。該結構對納米石墨薄片在聚合物基體中形成導電網路極為有利。 -
Fifty concrete filled thin - walled steel tubular stub columns were axially tested, where diameter ( width ) to thickness ratio was selected as the main varied parameter. the behaviour of concrete filled thin - walled steel tubular stub column was analyzed, and the simplified calculation method of bearing capacity was discussed. based on the current test results and those reported in the literature, the upper limits of d / t and b / t of cfst members were recommended
