一、等潜水位线图的常见考点考点一:潜水的埋藏深度潜水的埋藏深度是指地面到潜水面的垂直距离。因为等高线的数值代表该线上各点对应的地面海拔高度,等潜水位线的数值代表该线上各点对应的地下潜水面的海拔高度,因此,任一地点潜水的埋藏深度即是当地等高线数值和等潜水位线数值的差值。 First, the common test sites such as diving bitmap test point 1: diving depth of burial The depth of diving is the vertical distance from the ground to the diving surface. Because the values ​​of the contours represent the ground elevations corresponding to the points on the line, the values ​​of the phreatic lines represent the altitude of the underground surface corresponding to each point on the line. Therefore, the depth of burial for diving at any point is The difference between the local contour value and the value of the equivalent dive line.
