The author aims at the deficiencies of conventional anchor bolt detection apparatus based on the DOS platform of X86-framework,puts forward a ARM-Linux-based solution,and designs the application software of anchor bolt-quality detection using the Qt Designer in Linux,and actualizes the visual operation of the anchor bolt data collection.

One-dimensional wave equation model of the speed is inversed, this equation is established on anchor bolt practical problem.

The anchorage mechanism of the locking anchor under tension together shear loads is studied in the paper.

For understanding the stress state of locked anchor bars at the top of TGP permanent lock’s vertical slope,and effectively evaluating their construction qualities and anchoring effects,several anchor stress meters were located at partial locked anchor bars,and monitoring were practised.

Based on systematic research on the feet-lock bolt mechanism,and combined with the real construction conditions of feet-lock bolt in the soft and broken surrounding rock section of Xiamen subsea tunnel,a mechanical analysis model for feet-lock bolt was set up.

Full grouted prestressed anchor has characteristic of reliable auto-lock anchorage in tension section.
