Abstract
Abstract. In jiangxi red XiaShan highway tunnel interval for engineering background, the key research different scheme for tunnel construction process between them the mechanical behavior of rock and analyzed. For small interval double hole parallel tunnel between them the complex rock stress state, the finite element analysis software for using the numerical analysis method is buried deep in the condition of small interval period of bias by different construction scheme of tunnel numerical simulation. To meshshotcreting firstly method, CD method, up and down steps method, the construction method of different displacement and deformation of the stability of surrounding rock and the comparative analysis. Analyze the different schemes of before and after the surrounding rock tunnel excavation and supporting structure composed of each other of the unity displacement change rule. Put forward the tunnel between them weak rock the concept, more explicit the engineering geological conditions of weak rock tunnel clip to control surfaces. And on the basis of guidance for engineering construction, in actual construction which has obtained a better effect. The result is of a similar project design and construction to provide the reference and the model.
