浅论砼面板堆石坝设计

Discussion on the Design of a Rock-fill Dam With Concret Dam Face

砼面板堆石坝在我国起步较晚,但发展很快。该坝体断面大部分是按经验确定的,只有少数情况要进行稳定分析。坝体砼面和防浪墙的结构和布置,可参考已建工程而定。要重视填筑体的材料选择和分区。面板坝的设计大部分作二维有限元分析,少数作三维分析。对面板的施工要采取严格措拖,防止出现裂缝。

The rock-fill dam with concrete dam face was introduced into our country lately, but now it has been greatly developed. Main parts of the cross sections of the dam body can be determined by experience, and the others may be fixed up by the analysis of stability. The layout and structure of the concrete dam face and breakwater may be laid out by referring constructed projects. Designers must pay attention to the selection and arrangement of filling material and to the design of the dam mainly by use of 2-D finite element analysis and rarely by use of 3-D analysis. Some strict measures should be adopted during the construction in order to avoid producing crevices.
