| 摘要: |
| 设计阶段影响堆石坝工程投资预测的主要因素为砂石料的计价方式和上坝砂石料平衡调配方案.针对目前堆石坝工程设计概（估）算的编制主要存在砂石料计价不合理、上坝砂石料平衡调配重视不足、土石坝坝料压实定额的使用不准确及面板接缝止水子目缺项等问题，结合定额和工程实践分析了具体分项工程的砂石料计价方式和上坝砂石料平衡调配方案.在此基础上，根据坝体分区对筑坝材料的要求，提出土石坝坝料压实工序概算定额的合理组合和使用范围.同时根据已建混凝土面板堆石坝接缝止水的基本结构型式和材料的应用与施工情况，对面板接缝止水定额子目进行了修订和补充. |

| Abstract: |
| The principal factors influening on the rockfill dams engineering cost estimate in the design stage are the valuation of sandstone materials and balancing earth-rock works allocation. At present， a lot of questions such as the irrationality of the valuation of sandstone materials， the indifference of the balancing earth-rock works allocation， inexactitude compaction quota for earth-rockfill dam materials, and the hiatus in the quota items of the joint water-tight of the concrete face rockfill dams contain in the the compiled investment estimation of rockfill dam engineering， the valuation method of sandstone and the balancing earth-rock works allocation of the details subentry engineering are analyzed accordingly with the quota and practice. And based on the requirement for dam material of the zoning of the rockfill dam， proposing the reasonable combination and the usable range of budget estimate quota of compaction of soil rock in earth-rock dam working operation. And the quota items of joint waterstop of the concrete face rockfill dams are complemented according to the constructed basic structure of dams and the application of the material and construction situations. |
| Key words: rockfill dams cost estimate of sandstone balance of sandstone waterstop project quota |
