黄河万家寨水利枢纽工程左右岸坝肩排水平硐和灌浆平硐的开挖，由于岩石的疏松和节理发育等问题，给工程开挖带来了一定的困难，同时也给开挖断面的测量提出了新的课题。本文主要讨论该工程断面的测量方法以及测量队本着测量合理又经济、数据准确、及早提供成果等原则，为工程创下了较为可观的直接和间接经济效益等问题。

Because of soft rock and joint generation. It is difficult that the discharge and inject level hole on the shoulder of dam of Wanjiazhai Water Project on Yellow River was dug and the excavation section was surveyed. This paper raises problems in survey method of the project excavation section, and it is disscussed that successful survey caused Wanjiazhai Water Project more economic benefit.
