i'd like to know which normative or standard i may use to calculate the maximum force applied to the pipe during the jacking operation.

Thanks in advance


When you tell us what the anticipated geological conditions will be , then perhaps you can get answers


A bit less than it's allowable axial capacity which the vendor calculates for you ( at least for concrete pipe). Multiple jacking stations may be required for really long sections.

It's a calculation undertaken by the tunneling contractor in my experience.

Remember - More details = better answers
Also: If you get a response it's polite to respond to it.


Maybe I expressed myself in the wrong way. I want to know if there is a Standard, or
recognized and authoritative method, I can use to calculate the force applied to the pipe during the jacking operation (i.e : face resistance and lateral frictional resistance)

Thank you all in advance


which pipes : concrete ?


Yes, it's a concrete pipe


USA : Asce 27
Europe : EN 1916

I have a lot of doc (english, italian, spanish) : You can contact me at www.pisaniengineer.com (free doc, no charge at all - here I can't post because of copyright)
PS : your name seems italian
