Aim at the practical feature of rock pressure monitoring,the principles,structures and characteristics of several kinds of familiar rock pressure monitoring sensors has been introduced.

In view of the phenomenon of some bridges suddenly collapse in the construction process in recent years,some suggestions for accurate analysis of stress monitor of bridge s construction control were proposed.

The article introduces the key techniques in the construction monitor control of the unsymmetrical side-span pre-stressed concrete continuous box beam of Xiwuyi Canal Bridge at Changzhou section in 312 National Highway, discusses the purpose and meanings of the construction monitor control and sets forth the requirements and technical measures of the linear control and stress monitor.

Although the tradition way that using electric measurement technology dosen’t fit the concrete environment, the sensor based on fiber Bragg grating (FBG) is more suitable to the long-time stress monitoring.
