摘要
地质人员在勾绘地层界线（或断裂）的出露线时经常用到“V”字形法则，但“V”字形法则受地层产状及地形的坡向影响较大，且目前的“V”字形法则仅是地质现象的性质表述，没有量化指标，本文针对这种情况提出了应用“V”字形法则的量化指标，并且通过方法对比，提出了一种更加准确有效的勾绘地层界线（或断裂）出露线的方法，在实践中有较好的应用价值。
Geologists always use the v-like rule when they delineate the outcrop line of the stratum boundary or rupture. But the V-like rule is greatly influenced by the attitude of the stratum and topographical aspect and now it is just the property definition, without the quantitative index. Therefore, this paper puts forwards the quantitative index of applying the v-like rule, and through the method contrast, introduces a more effective method to delineate the outcrop line of the stratum boundary or rupture, which has preferable value in practice.
