陕西省最薄的拱坝——勉县板凳堰二级水电站浆砌石拱坝的设计与施工

The Thinnest Arch Dam in Shaanxi Province ——The design and construction of masonry arch dam for Bandengyan Hydropower Station

提出了岩石坝基上的低坝应充分考虑采用浆砌石薄拱坝的必要性与可行性。并扼要介绍板凳堰二级水电站浆砌石薄拱坝的设计与施工经验。枢纽最大坝高１３．０ｍ，坝体厚１．０￣１．４ｍ，是陕西省最薄的拱坝，有良好的研究和推广价值。

It is suggested in this paper that the thin cement-rubble masonry structure should be considered for the small dams on bedrock on the basis of the necessity and feasibility. A brief introduction was made to the design and construction for secondary stage dam of Bandengyan hydropower Station, which is a thin cement rubble masonry arch dam with the height of 13.0m and thickness of 1.0～1.4m. The dam is the thinnest arch dam in Shaanxi Province, its succeess is worth studying and spreading.
