Foreword

Since its promulgation and implementation, the "Code for Design of Highway Drainage" (JTJ 018-97) (hereinafter referred to as the original specification) has played an important role in reducing water damage to roadbeds and highway structures and improving highway durability. With the development of highway construction, the improvement of highway drainage technology, the emergence of new materials, and the accumulation of engineering experience, some parts of the specification need to be revised and improved to better meet the needs of engineering construction. According to the Ministry of Transport's "Notice on Releasing the 2009 Highway Engineering Standard Development and Revision Project Plan" (Jiaotongfa [2009] No. 190) requirements, China Jiaotong Road and Bridge Technology Co., Ltd. as the editor-in-chief shall revise the original specifications.
On the basis of summing up engineering practice experience and scientific research results in recent years, the editing team has fully absorbed the construction experience of drainage projects in recent years through extensive investigations, extensively solicited opinions from relevant units and experts in the industry, and completed the "Code for Highway Drainage Design" "(JTG / T D33-2012) (hereinafter referred to as this specification).
This specification consists of nine chapters and three appendices. The main contents include general requirements, surface drainage on road boundaries, internal drainage on road surfaces, underground drainage on road boundaries, highway structures, drainage through roads and facilities along the route, drainage in special areas and special sections, Hydrology and hydraulic calculation, etc. The main changes from the original specification are:
(1) A chapter on "General Requirements" has been added to systematically regulate the overall requirements and design contents of highway drainage design;
(2) The content of hydrological calculation and hydraulic calculation in the original code is combined into one chapter, and the contents of flow calculation and hydraulic calculation of underground drainage facilities are supplemented;
(3) Refined the regulations for surface drainage design of road boundary and internal drainage design of pavement;
(4) Added regulations on drainage design for tunnels, facilities along the line, and sensitive sections of the water environment;
(5) Added regulations for drainage design in some special areas and special sections.
The relevant units are requested to inform CCCC Road & Bridge Technology Co., Ltd. (Address: Jiangsu Building, No. 88 Andingmenwai Street, Dongcheng District, Beijing, 100011) for reference during the next revision.
