向量法在不规则隧道边仰坡面积计算中的应用

摘要

According to three - dimensional coordinate measured data of tunnel upward slope, the included angel between inclined plane of upward slope and projective horizontal plane is obtained through calculating the normal vector of the two planes, so as to back calculate the area of inclined plane of upward slope, which has wide application value in calculation of inclined plane area of similar irregular tunnel upward slope.%根据隧道边仰坡三维坐标测量数据，通过计算边仰坡斜面和投影水平面的法向量，进而计算两面之间夹角的方法，反算边仰坡斜面面积，在类似不规则隧道边仰坡等斜面面积计算中具有广泛的应用价值。
