广西灌阳新圩高速出入口加油站地质灾害特征及防治措施
Geological Disaster Characteristics and Prevention Measures of Xinwei High-Speed Exit Entrance Gas Station in Guanyang, Guangxi

通过野外调查新圩高速出入口加油站项目区域内各类地质灾害，基本查明其发育特征、稳定状态及其危害程度等，评估对工程建设中、后以及建设工程自身可能遭受的已存在的地质灾害的影响，并且针对不同地质灾害类型提出防治措施和建议。结果表明：现状地质灾害主要为不稳定斜坡和滑坡，其发育程度中等，危害程度及危险性小。预测挖方边坡发生滑坡、崩塌和岩溶塌陷地质灾害危险性中等；发生滑坡地质灾害危险性小或中等。针对以上可能发生的地质灾害，提出了浆砌石、防护网、生物消能、地面变形监测、灌浆加固及详细的岩土工程地质勘察等防治措施。
Through field investigation of all kinds of geological disasters in Xinwei high-speed exit entrance gas station project area, find out its development degree, steady state and its harm basically, and evaluation of project construction during and after construction project itself may suffer from the influence of the existing geological disaster, and in view of the different types of geological disasters prevention measures and suggestions are put forward. The study indicates that the present geohazards are mainly unstable slopes and landslides, which are medium-developed. Geohazards such as unstable slopes, landslides are less dangerous. It is predicted that the risk of collapse, landslide at the excavation slope and karst collapse is moderate, and the risk of landslide is small or moderate. Given the above possible geohazards, some prevention and control measures are put forward such as masonry, protective nets, biological energy dissipation, ground deformation monitoring, grouting reinforcement and detailed geotechnical engineering geological investigation.
