杭瑞国家公路凤凰至大兴(湘黔界)K0+500~K5+000段穿越凤凰国家地质公园奇梁洞景区。为分析公路施工期和运营期对奇梁洞地质遗迹影响程度,预测施工过程中爆破震动和项目建成后在车辆荷载作用下对地质遗迹造成的危害,利用有限元软件Plaxis模拟分析公路工程建设对地质遗迹的影响。为工程建设提供奇梁洞地质遗迹保护审批依据,防止建设工程引发地质灾害。
Hang-Rui National Highway Phoenix to Daxing (Hunan-Guizhou border) K0 +500 ~ K5 + 000 section through the Phoenix National Geological Park Qiliang Cave area. In order to analyze the influence of highway construction period and operation period on the geological relics of Qiliang Cave and forecast the blasting vibration in construction process and the hazard to geological relics caused by the vehicle load after the completion of the project, the finite element software Plaxis is used to simulate the impact of highway construction The impact of geological heritage. Provide the basis for examination and approval of geological relics for the construction of Qiliang Cave to prevent geological disasters caused by construction projects.
