摘要
在大比尺试验模型上，对充水式橡胶坝的坝袋表面作用力、坝袋变形、泄流量等随上下游水位及内水压的变化情况，作了细致的量测，并经整理分析，提出了橡胶坝在自由出流时的流量系统经验公式，供该类溢流橡胶坝设计参考．
rubber dam is a flexible structure, whose discharge changes with the upstream water level, downstream water level and internal water pressure. Today, there is no complete study about these factors. By model experiment, analyzed are the discharge and the shape of the dam. The relation of upstream water level, downstream water level, internal water pressure, discharge and the deformation of the dam' S are analyzed. Using the least square method, the discharge coefficient formula is given. This paper provides reliable data for projects and the research results are important to the design and study of rubber dams.
