Soil nailing is an in situ soil reinforcement technique that can be used to enhance the stability of slopes, retaining walls, embankments, and excavations. It involves installation of closely spaced, relatively slender unstressed tension-carrying structural elements into the ground to stabilize the soil mass. These elements, which are called soil nails, comprise steel or other engineering materials such as fiber reinforced polymer. Soil nailing did not gain popularity until the 1970s when engineers started to realize that the technique could offer an effective, robust, and economical reinforcing system for a variety of ground conditions. More importantly, the track record has been excellent in that no major collapses have been reported in properly designed and well-constructed soil nailed structures so far. Considerable experience and knowledge of the technique have been gained in the past few decades through systematic technical development work comprising laboratory tests, numerical modeling, physical modeling, site trials and field monitoring covering design, and construction practices.Soil Nailing: A Practical Guide consolidates the experience and advances made in the development and use of the soil nailing technique and encourages a wider adoption of the technique by practitioners. The book is intended for use by postgraduate students, researchers, and practicing civil and geotechnical engineers, who wish to have a more in-depth and fundamental understanding of the theory and practice behind the technique. It presents the basic principles of the technique as well as state-of-the-art knowledge and recommended standard of good practice in respect of design, construction, monitoring, and maintenance of soil nailed structures.

A unique, detailed account of the aces that flew in the bitter air fighting during the protracted eight-year war against Japan and the subsequent civil war against the Chinese CommunistsThe ace pilots of the Republic of China Air Force have long been shrouded in mystery and obscurity, as their retreat to Taiwan in 1949 and blanket martial law made records of the RoCAF all but impossible to access. Now, for the first time, the colourful story of these aces can finally be told. Using the latest research based on released archival information and full-colour illustrations, this book charts the history of the top scoring pilots of the RoCAF from the beginning of the gruelling, eight-year Sino-Japanese War to the conclusion of the Civil War against the Chinese Communists.Beginning as a ragged and very disparate group of planes and pilots drawn from various provincial air forces, the RoCAF gradually became standardised and was brought under American tutelage. Altogether it produced 17 aces who scored kills whilst flying a startling variety of aircraft, from biplanes to F-86 Sabres.
