pressures from box culvert to pipes
pressures from box culvert to pipes
(OP)
Hi I'm a civil engineer with basic knowledge in foundation designs.I hope to have a view on the analysis of this condition.
We will be laying a concrete culvert 1.5 m below ground level with pipes laid inside and is about 100meters length. Parallel to it, is a 20" diameter steel pipe laid in the ground 0.3meter beside the culvert edge and .35meter under the culvert edge.
Would someone help me on how to calculate the load or pressure from the culvert's edge to the pipe and will these loads/pressure reach the pipe, considering the short distances between them?

I have attached a section detail in my first thread. Thickness of the soil above the culvert s approx. 0.5 m, thickness of culvert's walls and base are 0.25m. 2 20" and 2 18" (oil) pipes are inside the RC culvert. In the attachment a pipe outside the culvert is parallel to the culvert at 0.328m away horizontally from the culverts edge of base and 0.358m bottom of the same edge. It could not be moved any farther because of the pipeline corridor space limit.
I have read about the 2:1 approximation (Boussinesq equation on how to get the vertical stress under foundations and how far its pressure would reach. Once I get the stress under the culvert and how far it is, I'll just check the stress capacity of the pipe and done. Am I having a right solution for it?
