| As the development of traffic construction of our country, especially the implement of western development strategy, the highway tunnel plan is leading to important increasingly in the high class highway construction of the mountain and the hills. And more and more mountain tunnels with different length and different type have been built up. So, to summary and study the monitoring technology in time, especially have a deeper understanding of the bad situation in the tunnel construction and grasp the successful experience and failure lesson from the tunnels already built up could provide important reference details and decision basis for newly built project, and also it is necessary for building up high way tunnels economically and high qualifiedly.In this paper, the advance geological forecast methods of highway tunnel are introduced in detail, and the merits and faults and the applicable conditions of each method are analyzed combined with the engineering practice of Qing-Shan tunnel. Based on the FLAC3D simulation, the stress and deformation and the plastic collapse degree are comprehensively analyzed, and the stress and deformation and the plastic collapse changing regular pattern of every working face site as the tunnel driving work face impel are generalized. All this work supply gist for the design of tunnel support parameter. This paper importantly study the information handling method of monitoring measurement and the practice of this technology in the Qing-Shan tunnel engineering, at the same time study the process of measurement information disposal, feedback and direction for the construction. The defective geological phenomenon is commented too.This paper generalizes the experience and achievement of monitoring measurement technology in the Qing-shan tunnel engineering practice in time, which administer to the application and popularization of monitoring measurement technology, and provide useable experience for future highway tunnel engineering...
