Explanation of Wording

This specification is formulated to standardize the engineering design of roller compacted earthrock fill dams to achieve the purposes of engineering safety, economy and rationality, and state-of-the-art technology.
　　This specification is applicable to the design of roller compacted earth-rock fill dams of Class 1 (the most important class) , Class 29 Class 3 and dams below Class 3 but higher than 30m. Special researches shall be performed for particularly important roller compacted earth-rock fill dams.
