Abstract:

The state of the art and future research in predrainage methods are discussed. The history of tunnel dewatering from the earliest recorded engineering efforts are described. The article states that tunnel dewatering systems should incorporate instrumentation to permit the unification of results sufficiently in advance of the tunneling operation so that any modifications can be made without impeding progress in the tunnel. The author concludes that the first step in dewatering is to understand the soils and their drainage characteristics and to provide the type of predrainage systems that can cope with the variation that may occur in soil drainage characteristics. Future research in this particular field includes the following: A basic understanding of pertinent soils and their drainage characteristics is necessary for making decisions on dewatering design, construction, and evaluation. Improvements should be made of the equipment and techniques that are used to install dewatering devices. And new techniques of hydraulic transfer of power and their applicability to the pumping field also require further research.
