"Design Standards and Commentary for Railway Structures (Earth Retaining Structures)" Price: ¥13,000 + tax This is an ex-library book, as shown in photo 11, but there are no issues with reading it. The ex-library sticker is on a blank page. While I believe there are no markings, I cannot guarantee it. Therefore, the price reflects this. Please be aware of this before purchasing. There are no plans to change the price. This is the final price. Please refrain from price negotiations. Thank you. ◆ Introduction to Contents This series provides commentary based on the "Design Standards for Railway Structures" issued by the Director-General of the Railway Bureau, Ministry of Land, Infrastructure, Transport and Tourism, with practical explanations by the Railway Technical Research Institute. This book comprehensively introduces performance-based design methods for the design of earth retaining structures (retaining structures and reinforced soil structures). Furthermore, it corresponds to the latest ground investigation methods and construction methods, and also explains high-performance materials and new construction methods in detail. In addition, major features of the content include: making it easy to compare and select retaining structures and reinforced soil structures, which were previously treated separately, by evaluating them using equivalent verification indicators; establishing a continuous design system for earth structures and bridges that considers the response characteristics during earthquakes for retaining walls and bridge abutments; and establishing a design system for backfill that considers construction with respect to materials, compaction, and drainage.
