摘要
以国道G323线乳源上围至沙坪段改建工程月街大桥#1主墩为研究对象,采用理论分析、现场监测及数值模拟方法研究#1主墩基础平台加固技术。采用平台注浆锚杆加固、鹰嘴石支撑肋梁及反压回填相结合的防护措施解决工程中的边坡稳定性问题,具有良好的工程实施效果。
The paper finds the research object from#1 main pier of Yuejie Bridge in the Reconstruction Project of Ruyuan Shangwei to Shaping Section of National Highway G323,which adopts theoretical analysis,field monitoring and numerical simulation to study the reinforcement technology of#1 main pier foundation platform.The slope stability issue in the project is solved by the combination of platform grouting anchor reinforcement,olecranon supporting ribbed beam and back pressure backfilling,which has achieved good engineering implementation effect.
