Based on the underground structure scheme of Langyashan hydro-electrical project, lots of elastic-plastic numerical analysis were conducted considering modulus of deformation, layout depth of underground opening, height of main factory premises, coefficient of lateral compressive stress, as the mainly mechanical parameters that influenced the stability analysis of underground openings. The mathematical statistics method was employed to investigate the displacement variation law of key point surrounding house periphery and found the forecast model. Then the forecast model was used to analyze the sensitivity parameters. It was shown that there was a good agreement between theoretic result and monitoring result in situ.
