摘　　要：大藤峡黔江副坝坝壳采用料源性质变化大,级配、含泥量极不均匀的弃渣料填筑,存在坝料质量控制难的问题,规范也无相应的控制标准。在弃渣料的应用过程中,根据坝料的勘察和试验成果,设计单位采用料性分析、压实条件分析、填筑标准及施工参数共同控制的综合方法,进行坝料设计及控制,取得了良好的效果,拓展了土石料的使用范围,也对土石坝工程类似坝料应用与控制起到了一定的借鉴作用。The shell of the secondary dam of Qianjiang River at Datengxia Gorge is filled with waste slag materials with a large change in material properties and uneven gradation and mud content.The quality of dam materials is difficult to control,and there is no corresponding control standard in the specification.In the application process of waste slag materials,according to the results of investigation and tests of dam materials,the design unit adopts the comprehensive method of material property analysis,compaction condition analysis,filling standards,and joint control of construction parameters to design and control the dam material.Through operation tests,the application of waste slag materials has achieved good results.This method expands the application scope of the earthrock and also provides a reference for the application and control of similar dam materials in earth-rock dam projects.
