The effect of underground structures on post performance is related to several factors. These factors would include the size and type of the obstruction, the location of the obstruction relative to the post, the orientation of the obstruction relative to the post, and the embedment depth obstruction relative to the post.
For the culvert pipe installation shown on your detail, the effects should be less than if the pipe ran in front of or behind the posts. We would recommend a minimum offset of 12 inches from the post for this type of installation.
