摘　　要：通过阐述工程点与勘探线之间的几何关系,给出它们之间几何关系的计算公式;借助3种不同的方法来获取工程点勘探线的偏离距和投影距。通过对这3种不同方法的对比得出的结论是:利用Excel表格计算更加简单和方便,可同时进行多点计算,提高工作效率。The relationship between engineering points and prospecting line is expounded, and the geometric relation-ship formulas between them are given. By using three different methods, the deviation distance and projection distance for engineering point are calculated. By comparing the three methods, the conclusion is that the method of using Excel table to calculate the deviation distance and projection distance can make calculation easier and more convenient, and it can be used to calculate several points at the same time and improve the work efficiency.
