Abstract: Based on the underground structure scheme of Longtan Hydropower Project, lots of elastoplastic numerical analysis were conducted considering modulus of deformation, layout depth of underground opening, height of main power house, coefficient of lateral compressive stress and spacing interval of underground houses as the mainly mechanical parameters that influenced the stability analysis of underground caverns. 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 engineerings. It is shown that there is a better agreement between theoretic result and monitoring result in situ[1].

Key words: stability of cavern, numerical simulation, regression analysis, displacement forecasting
