在分析在建特高拱坝上游止水区域的特殊表面裂缝产生原因的基础上,提出了取消大坝上游两道铜止水之间以及铜止水与止浆片之间的灌浆槽及管路施工建议,即对灌浆布置设计予以优化.基于本文提及的设计优化思想,采用大型结构多场仿真与非线性分析软件,研究了上游止水区域横缝不灌浆对特高拱坝的工作性态产生的影响.研究表明,上游止水区域横缝不灌浆对于上游横缝两侧的局部应力影响较为显著,但对结构整体变形和应力状态影响很小,从而验证了本文所提施工建议的合理性和可行性.
Based on the analysis of the causes of the special surface cracks in the water-stop area upstream of the UHMW Arch Dam, it is proposed that the grouting tank and the pipe between the two copper water stops upstream of the dam, Based on the idea of design optimization mentioned in this paper, a large-scale structure multi-field simulation and nonlinear analysis software is used to study the effect of the non-grout joint on the upstream water stop on the work of the UHV arch dam The results show that the non-grouting in the upstream sealing zone has a significant effect on the local stress on both sides of the upstream transverse joint, but has little effect on the overall deformation and stress state of the structure, thus verifying the proposed construction work proposed in this article The rationality and feasibility.
