基于多源信息融合的岚山区东山村滑坡隐患点勘察及其防治对策研究
Research on the Investigation and Prevention Measures of Landslide Hidden Danger Points in Dongshan Village, Lanshan District Based on Multi Source Information Fusion

以岚山区东山村为调查区，本文提出并完成基于多源信息融合的岚山区东山村滑坡隐患点勘察及其防治对策研究。通过定性及定量计算得：调查区滑坡处于基本稳定–欠稳定状态，通过稳定性计算分析，在天然状态，L1、L2、L3、L4四条剖面处于基本稳定状态；在饱和状态下4条剖面均处于欠稳定状态。滑坡在暴雨工况下，有可能产生整体变形失稳发生滑动。滑坡主要威胁对象为居住在坡体北部3户住户和森林防火人员共10人，潜在经济损失约29.6万元。滑坡地质灾害危险程度等级III级。建议在调查区完善群防群测体系，提高当地村民防灾减灾意识。当持续降水时，一旦发生整体滑坡或局部失稳破坏，可避免或减小灾害造成的人员伤亡与财产损失。滑坡前缘及滑坡体上禁止大面积开挖，形成新的临空面，以免加剧滑坡。这为日照市地质灾害的防治及工程治理提供坚实的资料基础，具有一定的实际应用价值。
Taking Dongshan Village in Lanshan District as the investigation area, this article proposes and completes the research on landslide hazard point survey and prevention measures based on multi-source information fusion in Dongshan Village, Lanshan District. Through qualitative and quantitative calculations, it was found that the landslide in the survey area is in a basically stable to unstable state. Through stability calculation analysis, in the natural state, the four profiles L1, L2, L3, and L4 are in a basically stable state; Under saturated conditions, all four profiles are in an unstable state. Under the rainstorm condition, the landslide may cause overall deformation, instability and sliding. The main threat of landslides is a total of 10 people, including 3 households living in the northern part of the slope and forest firefighters, with a potential economic loss of about 296,000 yuan. The hazard level of landslide geological hazards is Level III. It is recommended to improve the group prevention and measurement system in the survey area and enhance the awareness of local villagers in disaster prevention and reduction. When continuous precipitation occurs, once there is an overall landslide or local instability and damage, it can avoid or reduce the casualties and property losses caused by disasters. Large area excavation is prohibited on the front edge of the landslide and on the landslide body to form new free surfaces, in order to avoid exacerbating the landslide. This provides a solid data foundation for the prevention and engineering treatment of geological disasters in Rizhao City, and has certain practical application value.
