| Abstract: | The method of pre-setting steps in the first stage and one-time shaping with slip form in the second stage was adopted in construction of spillway surface with crest outlet.With high requirement of construction quality,the project is complicated in shape-type,and difficult in slip form construction.Based on an analysis of experimental results,some improvements were made in concrete performance,slip form design,and construction measures,and a set of mature slip form construction technique was formed.Practices show that the technique meets the design requirement of construction quality. |
