To keep pace with development of stone masonry dam construction and standardize the design of stone masonry dams, Design specification for stone masonry dams (SL25-91) is revised to this Code so that the stone masonry dam design could be safe and applicable, economically viable, technology updated and quality ensured. This Code is applicable to the design of Class 2 and Class 3 masonry dams for large and medium water resources and hydropower projects or Class 4 and Class 5 masonry dams over 50m high. It may also be used as a reference for the design of other masonry dams.為適應(yīng)砌石壩工程建設(shè)發(fā)展的需要，規(guī)范砌石壩設(shè)計(jì)，對(duì)《漿砌石壩設(shè)計(jì)規(guī)范》（SL25-91）進(jìn)行修訂，使砌石壩設(shè)計(jì)做到安全適用、經(jīng)濟(jì)合理、技術(shù)先進(jìn)、質(zhì)量保證，特制定本規(guī)范。本規(guī)范適用于大、中型水利水電工程中的2、3級(jí)砌石壩或壩高超過50m的45級(jí)砌石壩的設(shè)計(jì)。其他砌石壩設(shè)計(jì)可參照使用。
