| 摘 要： | 采用三维有限元精细模拟技术，对某抽水蓄能电站工程复杂渗流场进行计算，重点研究了深埋高压输水隧洞和岔洞钢筋混凝土衬砌开裂状态下洞室群围岩的渗流场分布特征。研究表明，在高压岔洞下游侧高压支管区设置防渗帷幕和排水孔幕组合防渗体系，对衬砌开裂状态下的高压渗水有显著控制作用，使该区域渗控效果基本满足要求，为下游厂房长期安全运行提供了保障。

| Abstract: | The complicated seepage flow field of a pumped storage power station project was simulated by 3D finite element refined simulation technology, the distribution characteristics of surrounding rock seepage field was studied in detail under lining cracks of the high pressure tunnel. The results show that the comprehensive measures for water tight curtain and drainage holes in downstream side of tunnel is effective under cracking hydraulic tunnel, so the seepage field can be controlled to reach up to the requirements, and the safety of the powerhouse is ensured in operating period. |
