Department of International Cooperation， Science and Technology of Ministry of Water Resources， P. R. China has the mandate of managing the formulation and revision of water technology standards in China.

Translation of the code from Cl：unese into English was organized by Department of International Cooperation， Science and Technology of Ministry of Water Resources， P. R. China in accordance with due procedures and regulations applicable in the country.

This English version of code is identical to its Chinese original SL 191-2008 Design Code for HydrauLic Concrete Structures， which was formulated and revised under the auspices of Department of International Cooperation， Science and Technology of Ministry of Water Resources， P. R. China.

《水工混凝土结构设计规范SL191-2008(SL 191-2008 替代 SL/ 191-96 和 SDJ 20-78)》是根据水利部水利水电规划设计管理局水总局科[2004]2号文，按照《水利技术标准编写规定》（SL 1-2002）的要求，由长江勘测规划设计研究院会同有关高等院校共同修订而成。《水工混凝土结构设计规范》（S1/T191-96）颁布后，由于和《水工钢筋混凝土结构设计规范》（SDJ20-78）并行使用，在安全度表达及考虑不同荷载的变异性上存在不一致，因此本次修订对以上两本规范进行了整合，对部分条文进行了合理修订，并补充了新的内容。

本标准共13章64节410条和7个附录，主要内容有：水工混凝土结构基本设计规定、材料、素混凝土结构构件计算、钢筋混凝土与预应力混凝土结构构件承载能力极限状态计算及正常使用极限状态验算、一般构造规定、水工结构构件的设计构造规定、温度作用设计原则、非杆件体系钢筋混凝土结构的配筋计算原则、钢筋混凝土结构构件抗震设计及有关附录。
