《混凝土重力坝设计规范SDJ21-78(试行)》自1978年颁发以来,已试行了6年。随着科学技术的发展和实践经验的不断积累,有些条文需作必要的修改和补充。1984年4月我部委托华东勘测设计院负责该规范补充规定的编制工作。在编制过程中,曾广泛征求意见,召开专门会议讨论研究。现批准《混凝土重力坝设计规范SDJ21-78(试行)补充规定》颁发试行。《混凝土重力坝设计规范SDJ21-78(试行)》中与本补充规定不一致的部分,以本补充规定为准。各单位在试行中有何意见,请随时函告我部水利水电规划设计院和华东勘测设计院。
“Design Specification for Concrete Gravity Dam SDJ21-78 (Trial)” has been piloted for 6 years since it was issued in 1978. With the continuous development of science and technology and practical experience, some provisions need to be modified and supplemented as necessary. April 1984 commissioned by the Department of East China Survey and Design Institute responsible for the regulation of the compilation of provisions. In the process of compiling, he has solicited opinions extensively and held special meetings to discuss the research. Now approved the “concrete gravity dam design specifications SDJ21-78 (Trial) Supplementary Provisions” issued for trial. The part of inconsistent with this Supplementary Provisions in the Design Specification for Concrete Gravity Dam SDJ21-78 (Trial) shall be subject to the Supplementary Provisions. All units in the trial of any comments, please feel free to write to I Water Resources Planning and Design Institute and East China Survey and Design Institute.
