| 摘 要： | 大岗山水电站坝肩边坡地质条件复杂，断层、岩脉、卸荷裂隙密集带、深部卸荷带及节理裂隙发育。为对该边坡在开挖支护过程中的应力、变形情况进行分析，采用弹黏塑性有限元软件EVP3D，利用弹塑性有限元法进行边坡稳定性的三维有限元计算，揭示边坡可能的失稳部位，对初拟的施工程序的合理性进行评价，并对边坡的支护方案提出建议。

| Abstract: | The abutment slope at Dagangshan Hydropower Project has complex geological conditions with faults,dikes,unloading crack intensive belt,deep unloading belt and developed joint fissures.In order to analyse the stress and deformation of the slope during the slope excavation and support,3D elastoplastic finite element simulation is performed with elastoplastic finite element method by the elasto-viscoplastic finite element software EVP3D,the possible failure location of the slope can be revealed,and the effecti... |
