25、erican Association of State Highway and Transportation Officials (AASHTO) Technical Committee on Hydrology and Hydraulics (TCHH), previously established as a Task Force in 1970, has produced a series of drainage manuals and guides. The TCHH produced this manual as part of their continuing work to as

26、sist the Standing Committee on Highways, Subcommittee on Design, in developing guidelines and in formulating policy. This publication supersedes the 2005 AASHTO publication, Model Drainage Manual. The AASHTO Drainage Manual provides transportation agencies with guidelines for establishing state-spec

27、ific policy and procedures for the design of highway drainage facilities. 1.2 SCOPE The TCHH has incorporated its numerous years of experience into this drainage manual to provide guidance on most aspects of highway drainage. Design, concepts, practices, manuals, policies, and procedures are condens

28、ed and written for use by the hydraulics engineer. Where appropriate, relevant existing AASHTO guidelines, including parts of the Highway Drainage Guidelines, are included or referenced. Due to significant topographical, climatological, and political differences throughout the nation, it is impossib

29、le to develop a meaningful and useful design manual that is a consensus document. Policies, criteria, and information that the agency may wish to use in the development of policy documents are included within each chapter and will require the States review for alteration or acceptance. Changes in th

30、e criteria or other portions of the manual are encouraged, and the recommended policies and criteria are not meant as recommended minimum standards, nor do they necessarily reflect an AASHTO consensus. This manual has been developed to provide hydraulics engineers with a basic working knowledge of h

31、ydrology and hydraulics. All basic design elements are included such that the hydraulics engineer can design highway drainage with minimal assistance. However, this manual cannot provide guidance on complex hydrologic or hydraulic problems, and it is no substitute for experience or engineering judgm

32、ent. 1.3 U.S. CUSTOMARY UNITS This manual has been published entirely in U.S. Customary units of measurement. Several factors influenced the decision to publish this document in U.S. Customary units: Substantially all states have reverted to U.S. Customary units of measure. The large amount of data

33、that is required prohibits a dual unit document. 2014 by the American Association of State Highway and Transportation Officials.All rights reserved.1-2 AASHTO Drainage Manual, Volume One “Policy” Many of the empirical equations were originally developed using U.S. Customary units. 1.4 MANUAL FORMAT

34、The manual is divided into two volumes. Volume One “Policy” provides states with guidelines or examples for drainage design policies, criteria, and standards. Volume Two “Procedures” provides hydrologic and hydraulic design procedures that are frequently used by highway hydraulics engineers. Volume

35、One chapters can generally be grouped into the five parts listed below: Part 1, General (Chapters 15). The introduction and chapters on legal aspects, data collection, and documentation provide recommended policies that apply to all drainage topics. Chapter 5 discusses the use of computer software f

36、or hydraulic analysis and design. Part 2, Planning and Environment (Chapters 68). Chapters on planning and location, surface water environment, and wetlands provide guidelines for policies and practices that are normally accomplished with the interaction of a hydraulics engineer before design. Part

37、3, Highway Hydraulic Design (Chapters 915). Chapters pertaining to hydrology, channels, culverts, energy dissipators, storm drainage systems, storage facilities, and pump stations provide design policies for facilities typically designed by highway hydraulics engineers. Part 4, Bridge Hydraulic Desi

38、gn and Floodplains (Chapters 1619). Chapters on stream stability, bridges, channel and stream bank stabilization, and coastal zone provide design policies for facilities typically designed by bridge hydraulics engineers. Part 5, Construction and Maintenance (Chapters 2022). Chapters about erosion an

39、d sediment control, construction, and maintenance provide guidelines for hydraulics engineers to provide assistance in these areas. Volume One chapters provide the following: guideline policy, criteria, and standard practices; reference to procedures in Volume Two; and overview of the subject. 1.5 M

40、ANUAL USE Volume One “Policy” has been written to provide examples of policies, criteria, and practices for highway agency use in establishing agency-specific processes and procedures. Some policies may not apply to a specific geographic region (e.g., coastal zone and wetlands). Specific design valu

41、es are provided for use on new construction or 2014 by the American Association of State Highway and Transportation Officials.All rights reserved.Introduction 1-3 reconstruction projects. States are encouraged to supplement these guideline policies with agency-specific design policies, methods, and

42、standards. 1.6 REFERENCES References are provided for all recommended procedures and where the hydraulics engineer may need more detailed source material. The references are listed in alphabetical order at the end of each chapter. Most reference documents are available on the internet and can be eas

43、ily found with a search engine. A few website addresses are provided for hard-to-locate documents or software. The hydraulics engineer should be knowledgeable in the use of the referenced items and be familiar with the issuing agencys website. 1.7 CONTENT QUESTIONS Questions on a particular chapter

44、or design procedure must be referred to the originating publications listed in the chapter references. AASHTO is not prepared to provide user services or answer questions. It is assumed that the agency is familiar with and competent in hydrology and hydraulics. Information can be obtained by contact

45、ing various State and Federal agencies (e.g., USGS, NRCS, FHWA, State highway departments, water resource agencies, FEMA, USACE), and colleges and universities. 1.8 ERRORS, ADDITIONS, AND UPDATES If errors are discovered in the manual, they should be reported to AASHTO so that corrections can be mad

46、e. Also, if states develop modifications and additions to the manual that would be of use to other agencies, copies should be submitted to AASHTO for inclusion in future updates. AASHTO does plan to issue updated changes to the manual. Updated versions of the manual will be distributed by AASHTO. 20
