| 摘 要： | 映秀湾水电站至今已运行30余年，由于其地下厂房围岩构造复杂，洞室顶拱纵横向裂缝密集．通过三维非线性有限元模拟分析，探明了顶拱纵横裂缝的成因及其对厂房结构安全的影响．经与实测资料对比分析表明，本模拟开裂区域与实测纵向主裂缝位置及环向开裂区域基本一致，成果合理可靠．

| Abstract: | Yingxiuwan Hydropower Station has operated for over 30 years. Because of the complicated geologic structure of surrounding rock, a lot of longitudinal and transverse cracks distribute on the crown of the underground powerhouse. With 3D nonlinear finite element method the fonnation cause of the cracks is studied, and then the influence of the cracks on the stability of the powerhouse is estimated as well. Compared with the measured data of the cracks, the simulated result herein is proved to be reasonable, for which the simulated cracking area is coincidence with the observed situation of the main longitudinal cracks and the circumferential cracking area. |
