围岩变形测量贯穿整个地下工程施工过程。为降低与施工活动的相互干扰影响，对测量系统的原位化、快速化、小型化及自动化提出了迫切需求。提出了一种能够大幅提高系统相对测量精度的分段间接围岩收敛变形参数测量方法；研制了可应用于数字近景摄影测量的便携式精密三维活动控制场，其网型结构可灵活配置且无需重新校验；在此基础上，采用非量测数码相机和直接线性变换算法建立了一套便携式围岩变形原位测量系统。验证性实验结果表明系统相对测量精度高，具有便携性及小型化、自动化的特点，易于实现现场快速化、原位化地下工程围岩变形参数监测。

Surrounding rock measurement is a very important job during the underground engineering construction. There are urgent requirements for the in-situ, rapidity and miniaturization performances of the measurement system in order not to affect the construction progress. According to practical working area situation, a indirect section deformation measurement method of surrounding rock was proposed. A novel portable precision 3D control filed was developed which could be configured to a specific state of controlling net and not need to be checked again. A digital close-range photogrammetry measurement system was setup based on non-metric digital camera and DLT algorithm. There are conclusions from the experiment results that the measurement accuracy of the system is high which has advantages of portability, miniaturization and automation, as easy to implement in-situ and rapid surrounding rock deformation measurements.
