论文部分内容阅读
原《水利水电技术》1979年第2期刊登了515科研组所写的“从515工程实践谈蓄水条件下的纵缝灌浆和简化大坝温控措施问题”的文章,读后颇受启发。觉得515科研组的同志所提出的关于有缝坝的一些问题,对工程具有现实意义,515工程所取得的一些经验是有价值的。下面就个人对有缝坝的认识,谈一些粗浅的看法。由于结构和施工方面的原因,大体积混凝土坝往往需要设置一些纵缝。因为,如果没有严格的温度控制,而又不采取合理的分块浇筑措施,大体积混凝土坝
The original “Water Conservancy and Hydropower Technology” 1979 the second issue of 515 research group wrote “from the 515 project practice under the conditions of water storage under the longitudinal grouting and simplify dam temperature control measures” article, after reading quite inspired . I feel that some of the problems raised by comrades in the 515 research group concerning the construction of a seam dam are of real significance to the project and some of the experience gained through the 515 project is of value. Below on the individual understanding of seam dam, talk about some superficial view. Due to structural and construction reasons, large-volume concrete dams often require some longitudinal slits. Because, if there is no strict temperature control, and do not take reasonable sub-block pouring measures, mass concrete dam
