摘要
通过两个模型的试验研究．论证了坝内钢管进人弹塑性状态工作的设想和方法．它对于充分发挥钢管作用．提高坝体混凝土的抗裂安全度，解决大直径、高水头坝内钢管制造安装工艺上的困难，具有较大的现实意义．
Penstocks in dams arc one kind of conduits widely used in power stations.With the developments of power stations of large capacity with high head, the design theory and methods used now have been becoming more and more difficult to meet cnginccring rcquircments. By,means of experiments of two models, this paper has veal fied the idea and method of penstocks in dams working in elastoptaltic state.It has big significance for bringing penstocks into full play,improving anti-cracking safety of concrete dam and overcoming difficulties in constructions of pcnstocks in dams with largc diameter and high bed.
