MECHANICAL PRESPLITTING. A NEW PROCESS OF TUNNEL CONSTRUCTION

LE PREDECOUPAGE MECANIQUE - UN PROCEDE NOUVEAU POUR LE CREUSEMENT DES TUNNELS

The authors describe the presplitting technique and outline the various stages of the method distinguishing between hard and soft ground. Chapter 2 deals more specially with presplitting in hard ground, the method used particularly suitable for urban works; the problems arising from the use of explosives in urban zones are outlined. Preliminary tests to the use of the method are described together with the advantages of mechanical presplitting in the case of tunnel construction with use of explosives. Chapter 3 describes applications of presplitting in hard ground. Chapters 4 and 5 concern mechanical presplitting in loose ground and its applications. (TRRL)
