DWA-A 161E - Static calculation of Jacking Pipes - March 2014, corrected version March 2021
This standard applies to the structural calculation of pipes with a circular cross-section which are installed according to the pipe jacking method in a straight or bending direction in non-cohesive or cohesive soils (loose soils as according to DIN 18319) with static force in accordance with Standard DWA-A 125/DVGW GW 304. For jacking in solid rock, either wholly or in part, there is no standard solution in this regard, instead, special considerations are to be made; for example application of smaller bearing angles and earth load over the pipe crest.
