摘　　要：在施工过程中,测量是不可缺少的一部分。传统的测量使用的工具之一是棱镜,不仅要架设全站仪,同时也要选点架设棱镜,通过全站仪与棱镜之间的反射测量距离与角度,这样会花费大量的时间。免棱镜测量技术则不然,对反射物不做严格要求,目标位置的石头、墙体、金属体就可以反射信号,在铁路隧道监控量测中,由施工队打下钢筋并放置反光片作为目标,仪器架设好直接就能测量,节省了大量的时间。In the construction process,measurement is an indispensable part.Traditional measurement uses a prism cooperatively,it not only sets up a total station,but also selects a point to set up the prism,and it measures the dis-tance and the angle through the reflection between the total station and the prism,which takes a lot of time.Non-prism measurement technology is not the same,which does not have strict requirements for reflectors,and stones,walls and metal bodies at the target location can reflect signals.In the monitoring and measurement of railway tun-nels,the construction team lays steel bars and places reflectors as targets,and instruments can be directly used for measurment after they are set up,saving a lot of time.
