                                  Any engineering guidelines for the required distance between two parallel bored tunnels?

                                  Hi, I am looking for any academic papers, engineering guidelines for the required separation between two parallel running tubes. Like its relationship to tunnels' diameter, geological properties etc. Your help appreciated! Regards, Heiko
