“…It is further assumed that the earth pressure coefficient at-rest of the backfill material is K o = 1.0, to account for any accidental compaction of the sand -although compaction of the backfill in areas where relative ground surface deformations are expected should be avoided, as a denser backfill will introduce higher reaction forces on the pipeline. Note that the uplift yield displacement in Table 1 is derived by fitting a bilinear force-displacement curve to the hyperbolic equation proposed by Trautmann et al (1985).…”

“…The latter is different for upwards and downwards movement (see, for example Trautmann et al 1985 andKouretzis et al 2014), but a mean value will be assumed for these particular segments, for the sake of simplicity. The boundary conditions for eq.…”

“…The maximum lateral soil resistance per unit length, corresponding to the undrained state, is computed as proposed by Trautmann et al (1985) and Poulos and Davis (1980) The factor N c depends on the ratio of burial depth (H)t o pipe diameter (D). For typical pipe sizes and burial depths, the ratio H/D can vary between 3 and 20.…”

“…The extreme condition is often identified as the ''liquefied'' state of soil. The occurrence of this state may lead to the flow of the soil mass, which is usually catastrophic Seismic performance of pipelines has been studied by Trautmann et al [30] and Newmark and Hall [7]. Karamitros et al [11] presented an analytical methodology to simulate buried pipeline behavior under permanent groundinduced actions.…”
