System Analysis Method in Underground Openings Excavation and Application
Based on the underground structure scheme of LONGTAN hydro-electrical project, lots of elastic-plastic numerical analysis are conducted considering modulus of deformation, layout depth of underground opening, height of main factory premises, coefficient of lateral compressive stress and pacing interval of underground houses as the mainly mechanical parameters that influence the stability analysis of underground caverns. The mathematical statistics method is employed to investigate the displacement variation law of key point surrounding house periphery and find the forecast model. Then the forecast model is used to analyze the engineering. It shows that there is a better agreement between theoretic results and monitoring result from in situ.
