双曲拱坝,坝顶高程610.0 m,最低建基面高程332.0 m,最大坝高278.0 m,拱冠断面底宽约60.0 m,最大宽度64 m,坝顶宽度14.0 m,坝顶轴线弧长681.49 m,坝体混凝土558万m3,整个坝体分为31个坝段。鉴于大坝工程的重要性,其施工进度又处于工程施工本文从建筑物、地形地质、施工进度等方面分析了溪洛渡水电站大坝的施工特性;针对不同缆机布置、坝体混凝土浇筑方案,提出了大坝混凝土浇筑的计算机仿真方法,阐述了仿真计算的过程及成果,分析并确定了坝体接缝灌浆方案;提出了大坝工程详细的施工进度计划和施工方案。
The double crest arch dam has an elevation of 610.0 m with a minimum elevation of 332.0 m and a maximum height of 278.0 m. The bottom width of the crown is about 60.0 m, the maximum width is 64 m, the width of the crest is 14.0 m. 681.49 m, 5.58 million m3 concrete dam, the dam is divided into 31 dam sections. In view of the importance of the dam project, the construction schedule is in the process of construction. In this paper, the construction characteristics of the Xiluodu Hydropower Station dam are analyzed from the aspects of building, topography and geology, construction progress, etc. In view of different cable machine layouts and dam concrete pouring schemes, The method of computer simulation of concrete pouring is described. The process and result of the simulation calculation are expounded, the grouting scheme of the joint of the dam is analyzed and confirmed, and the detailed construction schedule and construction scheme of the dam are proposed.
