Target audience of this Standard are the professionals in municipalities, associations, planning offices and
authorities involved with static calculation of jacking pipes and planning of trenchless construction methods.
Standard DWA-A 161E Static Calculation of Jacking Pipes
Statische Berechnung von Vortriebsrohren
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 per 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.
These calculation approaches and material characteristics are based on the pipe materials as per Annex A of
this Standard. This Standard can be applied analogously to pipes that are driven with dynamic energy. Unless
otherwise mentioned in this Standard, it also applies to pipe jacking using related methods with the appropriate
adjustments. For pipes installed within a jacking path in an open-cut method of construction in shafts or
connecting paths, Standard ATV-DVWK-A 127 applies.
