A basal reinforced piled embankment consists of a reinforced embankment on a pile foundation. The reinforcement consists of one or more horizontal layers of geosynthetic reinforcement installed at the base of the embankment. A basal reinforced piled embankment can be used for the construction of a road or a railway when a traditional construction method would require too much construction time, affect vulnerable objects nearby or give too much residual settlement, making frequent maintenance necessary. This publication is a guideline (CUR226) for the design of basal reinforced piled embankments. The guideline covers the following subjects: a survey of the requirements and the basic principles for the structure as a whole; some instructions for the pile foundation and the pile caps; design rules for the embankment with the basal geosynthetic reinforcement; extensive calculation examples; finite element calculations; construction details and management and maintenance of the piled embankment. The guideline includes many practical tips. The design guideline is based on state-of-the-art Dutch research, which was conducted in cooperation with many researchers from different countries.

Geotechnical Risk and Safety V contains contributions presented at the 5th International Symposium on Geotechnical Safety and Risk (5th ISGSR, Rotterdam, 13-16 October 2015) which was organized under the auspices of the Geotechnical Safety Network (GEOSNet) and the following technical committees of the of the International Society of Soil Mechanics and Geotechnical Engineering (ISSGME): • TC304 Engineering Practice of Risk Assessment & Management • TC205 Safety and Serviceability in Geotechnical Design • TC212 Deep Foundations • TC302 Forensic Geotechnical Engineering Geotechnical Risk and Safety V covers seven themes: 1. Geotechnical Risk Management and Risk Communication 2. Variability in Ground Conditions and Site Investigation 3. Reliability and Risk Analysis of Geotechnical Structures 4. Limit-state design in Geotechnical Engineering 5. Assessment and Management of Natural Hazards 6. Contractual and Legal Issues of Foundation and (Under)Ground Works 7. Case Studies, Monitoring and Observational Method The 5th ISGSR is the continuation of a series of symposiums and workshops on geotechnical risk and reliability, starting with LSD2000 (Melbourne, Australia), IWS2002 (Tokyo and Kamakura, Japan), LSD2003 (Cambridge, USA), Georisk2004 (Bangalore, India), Taipei2006 (Taipei, Taiwan), the 1st ISGSR (Shanghai, China, 2007), the 2nd ISGSR (Gifu, Japan, 2009), the 3rd ISGSR (Munich, Germany, 2011) and the 4th ISGSR (Hong Kong, 2013).

Geotextiles: From Design to Applications presents valuable information on the high performance fabrics used in soil separation, drainage, filtration, reinforcement, and cushioning. These polymeric materials offer solutions for geoengineering and other civil engineering specialties due to their advanced physical, mechanical, hydraulic, and endurance properties. This important book offers comprehensive coverage of the manufacture, functions, properties, designs, and applications of geotextiles. Part One begins with a chapter on the history of geotextiles, followed by chapters giving detailed reviews of the types of fabrics and their manufacturing processes, from resin type, to fiber extrusion, to textile fabrication. Part Two covers the properties, behavior, and testing of geotextiles, with Part Three focusing on applications dealing with the specific primary functions of geotextiles. In Part Four, chapters offer numerous general applications of geotextiles, including those in waste containment, marine engineering, walls/slopes, agriculture, and erosion control. Finally, the chapters of Part Five address quality control and assurance for geotextiles, and the increasingly important topic of sustainability. Reviews the types of fabrics used for geotextiles and their manufacturing processes Covers the properties, behavior, and testing of geotextiles Contains detailed discussions of the primary functions of geotextiles and their wide range of applications

Gain a stronger foundation with optimal ground improvement Before you break ground on a new structure, you need to analyzethe structure of the ground. Expert analysis and optimization ofthe geo-materials on your site can mean the difference between alasting structure and a school in a sinkhole. Sometimes problematicgeology is expected because of the location, but other times it'sonly unearthed once construction has begun. You need to be able toquickly adapt your project plan to include an improvement tounfavorable ground before the project can safely continue. Principles and Practice of Ground Improvement is the onlycomprehensive, up-to-date compendium of solutions to this criticalaspect of civil engineering. Dr. Jie Han, registered ProfessionalEngineer and preeminent voice in geotechnical engineering, is theultimate guide to the methods and best practices of groundimprovement. Han walks you through various ground improvementsolutions and provides theoretical and practical advice fordetermining which technique fits each situation. Follow examples to find solutions to complex problems Complete homework problems to tackle issues that presentthemselves in the field Study design procedures for each technique to simplify fieldimplementation Brush up on modern ground improvement technologies to keepabreast of all available options Principles and Practice of Ground Improvement can be usedas a textbook, and includes Powerpoint slides for instructors. It'salso a handy field reference for contractors and installers whoactually implement plans. There are many ground improvementsolutions out there, but there is no single right answer to everysituation. Principles and Practice of Ground Improvementwill give you the information you need to analyze the problem, thendesign and implement the best possible solution.

2 nung der durch Änderungen in der Belastung und in den Entwässe rungsbedingungen verursachten Wirkungen meist nur sehr gering sind. Diese Feststellung gilt im besonderen Maße für alle jene Auf gaben, die sich mit der Wirkung des strömenden Wasser befassen, weil hier untergeordnete Abweichungen in der Schichtung, die durch Probebohrungen nicht aufgeschlossen werden, von großem Einfluß sein können. Aus diesem Grunde unterscheidet sich die Anwendung der theoretischen Bodenmechanik auf den Erd- und Grundbau ganz wesentlich von der Anwendung der technischen Mechanik auf den Stahl-, Holz- und Massivbau. Die elastischen Größen der Baustoffe Stahl oder Stahlbeton sind nur wenig veränderlich, und die Gesetze der angewandten Mechanik können für die praktische Anwendung ohne Einschränkung übertragen werden. Demgegenüber stellen die theoretischen Untersuchungen in der Bodenmechanik nur Arbeits hypothesen dar, weil unsere Kenntnisse über die mittleren physikalischen Eigenschaften des Untergrundes und über den Verlauf der einzelnen Schichtgrenzen stets unvollkommen und sogar oft äußerst unzuläng lich sind. Vom praktischen Standpunkt aus gesehen, sind die in der Bodenmechanik entwickelten Arbeitshypothesen jedoch ebenso an wendbar wie die theoretische Festigkeitslehre auf andere Zweige des Bauingenieurwesens. Wenn der Ingenieur sich der in den grundlegen den Annahmen enthaltenen Unsicherheiten bewußt ist, dann ist er auch imstande, die Art und die Bedeutung der Unterschiede zu er kennen, die zwischen der Wirklichkeit und seiner Vorstellung über die Bodenverhältnisse bestehen.
