J. Cent. South Univ. Technol. (2011) 18: 1654-1661 DOI: 10.1007/s11771-011-0885-1 Strain analysis of buried steel pipelines across strike-slip faults WANG Bin(王滨), LI Xin(李昕), ZHOU Jing(周晶...: Existing analytical methods of buried steel pipelines subjected to active strike-slip faults depended on a number of simplifications. To study the failure mechanism more accurately, a refined strain......
