海南省陀兴水库浆砌石重力坝改扩建方案研究

陀兴水库建于20世纪六七十年代,由于当时设计和施工条件有限,经过多年运行后年久失修,需将浆砌石重力坝加高培厚。根据坝址区地质勘探资料及坝体钻孔揭露情况,拟定了三种改扩建方案。为了确保工程扩建后的正常运行,从渗透稳定性、结构安全性、抗滑稳定性和工程投资等多个方面进行了对比论证,以便为工程的顺利实施提供参考。

Study on improvement and enlargement scheme for masonry gravity dam of Tuoxing Reservoir in Hainan Province

As built in the 1960s~1970s, the masonry gravity dam of Tuoxing Reservoir is aged and out of repair for long years due to the limited conditions for both the design and the construction at that time, and then the masonry gravity dam is necessary to be heightened and thickened. In accordance with the geological prospecting data and the actual condition of the dam exposed by the drilling investigation, three schemes for the improvement and enlargement of the dam are worked out herein. In order to ensure the normal operation after the enlargement of the project, the comparison and verification in the aspects of the seepage stability, structural safety, anti-sliding stability, project investment, etc. are made, so as to provide the relevant references for the smooth implementation of the project.
