How to do a wedge analysis for a dead man anchor

[ac4u2nv]

Hi im trying to calculate if a dead man anchor with the following specs would be sufficient provide enough resistance for a HDD drill rig.

How would i calculate the forces and what factors should i consider?

A steel fabricated water filled buried container (known as a fabricated dead-man). The dimensions of the steel container for the 500 ton rig could be L x W x D = 5m x 2.5m x 2.5m.

The maximum pull capacity of the drill rig is 200tonnef

Any ideas would be greatly appreciated


Thank you

sounds like homework

For one thing you need soil and ground water physical information and some idea of how they are usually used. It probably requires that you have had a course in descriptive geometry as well as a complete description of the tank itself in addition to the overall dimensions. You will not get a sample set of computations here however. Try a Google search for some guide publications on the subject, such as NAVFAC.

calculate the passive resistance and multiply it by phi/10.
