During the construction stage, the curtain grouting works of both the left and right bank dam contracts encountered with the problem that "the total length of drilling holes increases greatly while the total amount of grouting decreases greatly, and the unit grouting rate is far lower than the value assumed in the bidding stage". Accordingly, the contractors submitted the change requirements for the related unit prices and measurement methods. Therefore, based on the actual construction situation of curtain grouting and relevant designs and test data, a special analysis and research was carried out. The original measurement mode in one unit price for grouting was replaced by the mode consisting of new unit prices of seven continuous intervals of grout consumption, and composed of under the sector norms and the market discount factor. The set of unit prices were further back-calculated on the principle of management indirect cost equation of contract and readjusted in reasonable range. Further, the measurement method was slightly changed to be made on the unit of meter for low grout consumption interval by learning similar projects experiences. Finally, a measurement proposal was concluded and recommended for the settlement of contract problem. 【Keyword】 Hydropower project; Dam curtain grouting; Grouting measurement; Change in unit rate 作者简介：王 燕（1969— ），女，江苏常州人，高级工程师， 主要从事水利水电工程造价和咨询、工程计价工作。 乔月宾（1980— ），男，四川成都人，高级工程师，主要从事水利水电工程造价和咨询工作。 收稿日期：2020年3月 水电站大坝帷幕灌浆合同价格调整研究 王 燕 乔月宾 朱明润 （中国电建集团成都勘测设计研究院有限公司，四川成都
