光电测距三角高程测量在铁路勘测中的应用（一）

The Application of the Photoelectric Distance Measurement with the Short-sided Triangle Formula in Railway Survey

随着光电测距技术的发展，光电测距短边三角高程测量在铁路勘测中代替过去的几何水准测量，加快了勘测进度，简化了工作程序．本文通过对实践资料的整理，分析总结了在不同地形条件下光电测距三角高程测量在铁路勘测中的应用．

With the development of photoelectric technology, the photoelectric distance measurement with the short-sided triangle formula has taken the place of geometric standard measurement that used to be. It has accelerated the Survey progress and simplified the working procedures. Through a certain arrangement to some practical materials, this essay analyzes and summarizes the application of photoelectric measurement with the short-sided triangle formula in different geographic conditions.
