This page analyzes the response of the pipe to ground movements induced by geotechnical activities, e.g., ground heave and subsidence, slope instability, landslides, liquefaction-induced action, and tectonic faults. In this calculation, the pipe is divided into three segments (the left segment L1, the middle segment L2, and the right segment L3) in which the middle segment is subjected to the ground movement. The length of the middle segment is case-specific. In contrast, the length of left and right segments should be determined considering the elimination of the fixed boundary effects at the two ends. The analysis is performed based on a 2-dimensional model where the pipe is deformed in the axial and lateral directions. The finite difference method is employed for the response calculation.
