摘要
介绍并分析了清江水布垭工程地下厂房洞室群的锚固方案。在二维分析中比较了无锚工况和有锚工况围岩状况的差异以及不同初始地应力场时的差异。对系统锚杆做了3种不同方案的比较。在三维分析中,比较了3种不同吨位长锚索的加固效果。最后,得出了相应的结论。
The optimazation analysis is described on reinforcing scheme for underground power house of Shuibuya Project.In 2D analysis,the comparison of different rock conditions is made for the cases with and without reinforcement under different initial stresses.Three different schemes for systematical rock bolts are compared.In 3D analysis,the comparison of reinforcing effect is made for 3 schemes of prestress cable with different tonnage. Some relevant conclusions are given finally.
