By means of the finite element analysis, the deep hole structure plan, steel liner in the pressure section plan and the transverse joint grouting plan are deeply researched in order to decrease the outlet tensile stress and reduces the lays of t.
为降低孔口拉应力,减少配筋层数,通过有限元计算方法,对深孔结构基本方案、有压段钢衬方案、横缝灌浆方案等不同结构措施的深入研究,孔口结构受横缝侧水压力作用后,孔口拉应力得以降低,事故门井前孔口配三层36@20的钢筋,门井后孔顶配四层40@20的钢筋,孔底配三层40@20的钢筋,多层钢筋可分散布置在两个浇筑层内。

533 M m3 , and water cooling and joint grouting in concrete structure at the middle section of it were first applied in the world; the transverse cofferdam that should be placed within 4 months has a maximum height of 115 m with a crest length of 580 m and a volume of 1.
在纵向围堰中部的坝身段碾压混凝土结构内首次实现通水冷却和接缝灌浆。
By using emulative visco elasticity three dimension finite element method, the water pipe cooling for joint grouting of concrete dams has been studied in this paper.
采用全过程仿真粘弹性空间有限单元法对接缝灌浆水管冷却问题进行了计算研究 ,对冷却水温、冷却延续天数进行了敏感性分析 ,提出了只进行一期水管冷却 ,并在适当“超冷”情况下进行大坝接缝灌浆的建议 ,不但简化了施工步序 ,也有利于大坝的整体性 ,计算研究结果可供混凝土坝施工设计参考应用 。
