| 摘 要： | 利用岩土工程软件FLAC-3D对朱昌河特大桥4#主墩基础边坡岩体在自然条件下,桩及承台施工过程、锚杆(索)加固过程以及施加设计荷载状态下的变形及稳定性进行了三维数值模拟分析。结果表明:在上述条件下,4#主墩基础边坡岩体是稳定的,水平位移量和垂直位移量均在设计范围以内。从长远来看,为确保大桥的安全运行,对4#主墩基础边坡进行加固是必要的。

| Abstract: | Geotechnical engineering software FLAC-3D was used to analyze and simulate Zhuchang river special bridge 4~# main pier foundation deformation and stability of slope rock mass under the condition of nature,construction of pile and carry,consolidation of anchor bar(rope) and existing design load.The results indicts that above those conditions,4~# main pier foundation slope rock mass is stable,and its horizontal displacement and vertical displacement meets design demands.In the long run,it is essential to reinforce 4~# main pier foundation slope rock mass. |
