控制理论

According to the construction course and finished dead state of the inclined tower cable-stayed bridge without back stay at Tongling Road in Hefei and combining the modern theory and method of the bridge construction control mentioned in this paper, established a space model by large-scale general finite element software ANSYS. It can obtain some valuable result by emulating analysis of the bridge which is under the construction course and finished dead state. It can provide an instruction for the Tongling Road bridge with the result and construction job site monitoring data.

Considering the theory of roadway support in soft rock, we proposed an active support mode based on study of rheology of weak adjacent rock, complex stress environment, and destabilization of original supports. Fully grouted bolt, extension grouted cable that can strengthen self-bearing capacity and entirety are used. Original support scheme and reinforcement scheme are simulated by means of FLAC(superscript 3D).
