在建設大型水工隧洞、埋藏式高压管道和地下厂房等地下建筑物时,充分了解岩体中的原始应力分布情况,以及合理确定弹性抗力系数值,对保証建筑物的經济合理和安全运行具有重要意义。为此,水利水电建設总局結合以礼河水电工程的需要,組織有关单位在現場进行了一系列科学試驗,他們在缺乏經驗的情况下,找到了合理的試驗方法,为設計与施工取得了有价值的第一性资料。为了促进这項新技术的发展,本刊特发表“岩体应力测量技术”一文,近期还将发表“以礼河电站地下鋼管支洞水压試驗”一文。希望有关单位进一步試驗研究,以便在这方面取得更完善的經驗,更好地为生产服务。
When constructing large-scale hydraulic tunnels, buried high-pressure pipelines and underground powerhouses and other underground buildings, a full understanding of the original stress distribution in the rock mass and a reasonable determination of the value of the elastic resistance coefficient have the effect of ensuring the economical and reasonable operation of the building. Significance. To this end, the General Administration of Water Conservancy and Hydropower Construction, in conjunction with the needs of the Lihe Hydropower Project, organized related units to conduct a series of scientific experiments on the site. They found a reasonable test method in the absence of experience, and achieved the design and construction. First-rate information on value. In order to promote the development of this new technology, the magazine published the “rock mass stress measurement technology” article, and will also publish the article “Pressure test of underground pipe branch holes in Lihe Hydropower Station” in the near future. It is hoped that the relevant units will further experiment and research in order to obtain more complete experience in this area and better serve production.
