摘要
该研究对简阳市东西城市轴线沱江大道沿线的地质、气象及水文特征进行详细分析,探讨该区域工程建设可能引发的地质灾害类型、成因及其防治对策。通过野外调查与遥感解译,识别研究区内主要的地质灾害类型,包括滑坡、崩塌、不稳定斜坡及泥石流。结果表明,研究区处于四川东部的相对稳定构造单元内,但由于地处红层丘陵地带,岩土层结构较松散且差异显著,再加上降水充沛,致使该区域的地质灾害风险增高。工程施工中的地表开挖、爆破振动及坡体加载可能诱发滑坡、崩塌等灾害。针对上述灾害风险,该文提出综合的防治措施,包括构建排水系统、坡体加固、科学施工管理及多层次监测预警系统,以减少工程扰动引发的地质灾害,保障施工安全。该研究结果为类似地质条件下的基础设施建设提供科学指导,并为区域地质灾害的有效防控提供技术参考。
This study provides a detailed analysis of the geological,meteorological,and hydrological characteristics along the East-West Urban Axis of Tuojiang Avenue in Jianyang City,focusing on the types,causes,and mitigation strategies for geological hazards potentially induced by construction activities in this area.Through field investigations and remote sensing interpretation,the primary types of geological hazards identified include landslides,collapses,unstable slopes,and debris flows.Results indicate that the study area is located within a relatively stable tectonic unit in eastern Sichuan;however,the region's red-bed hilly terrain,characterized by loose and heterogeneous rock and soil structures and abundant precipitation,heightens the geological hazard risk.Construction activities such as surface excavation,blasting,and slope loading have the potential to trigger landslides and collapses.To address these risks,this paper proposes a set of comprehensive mitigation measures,including drainage system construction,slope reinforcement,scientifically informed construction practices,and a multi-tiered monitoring and early warning system to reduce the likelihood of construction-induced geological hazards and ensure construction safety.The findings offer scientific guidance for infrastructure projects in similar geological settings and provide technical references for effective regional geological hazard prevention and control.
