在水电建設坝址的工程地質勘测中,地質人员必须經常向設計人員提供地貿图紙,其中使用的最多的要算平面图和剖面图。特別是地貿剖面图更是設計人員計算工程量,考虑水工布置及施工措施的重要依据之一。因此,如何使这些图能够真实而清楚的反映工 In engineering geological survey of hydroelectric dam site, geological staff must provide the designer with trade and trade drawings frequently, and the most used ones are plan and section plans. In particular, the trade profile is a designer to calculate the amount of engineering, hydraulic arrangements and construction measures to consider an important basis. Therefore, how to make these figures truly and clearly reflect the workers
