Notes:
Based on the underground structure scheme of Langyashan hydro-electrical project, lotsof elastic-plastic numerical analysis were conducted considering modulus of deformation, layoutdepth of underground opening, height of main factory premises, coefficient of lateral compressivestress, as the mainly mechanical parameters that influenced the stability analysis of undergroundopenings. The mathematical statistics method was employed to investigate the displacementvariation law of key point surrounding house periphery and found the forecast model. Then theforecast model was used to analyze the sensitivity parameters. It was shown that there was a goodagreement between theoretic result and monitoring result in situ
