lateral soil reaction for embedded length of a temporary fence made of steel pipe
lateral soil reaction for embedded length of a temporary fence made of steel pipe
(OP)
is there any simple method to approximate the horizontal subgrade modulus of the soil when the fence experiences wind load? Im trying to calculate whether the setup will overturn or not, i honestly don't know how to deal with the soil reaction part to get the righting moments.

If you you need to work out over turning then you need to be assessing the overturning force, which is your wind load. And your resisting force, which is weight of concrete and passive resistance.
Your embedment is only 1m deep. Many engineers ignore passive for the upper 1m as the ground could be desiccated or subject to freeze/thaw.
On that basis I would only use weight of concrete as resisting force. If you are really pushed to make that work and you are confident there is no desiccation or freeze thaw then maybe you could use the bottom 0.5 as passive.

Not in these environs; our highly plastic clays almost never desiccate more than a few inches. Embedment of metal posts for 'chainlink' type of fence may only be 1.2m.
Check for these on the web... I can post them here if you are unable to locate them.
