随着江西省1/5万地质灾害调查分批分期的展开、经验的不断累积,与此相关规范、规定不断更新,更趋向于细化、标准化。新干县是江西省最后一批下达任务的县(市)之一,同时也是调查工作最早启动的县,全县以平原岗丘地貌为主,人类工程活动引发、自然形成的地质灾害不多。本文着重分析、总结出新干县地面调查建卡的调查方法和技术要点,使原本调查点就不够的地面调查定点建卡工作在新规范下能够保质保量地完成任务。同时,为同批乃至全国相似情况县(市)的地灾调查工作提供借鉴和可靠的经验。
With the 1/50000 geological disasters survey in Jiangxi Province launched in batches, the experience accumulated continuously, with which the relevant norms and regulations are constantly updated and tend to be refined and standardized. Xingan County is one of the last counties (cities) dispatched in Jiangxi Province. It is also the earliest county to start the investigation. The whole county is dominated by plain hills and mounds, and triggered by human engineering activities, there are not many geological disasters that naturally occur . This article focuses on analysis and summarizes the investigation methods and technical points of the ground survey card construction in Xingan County so that the ground investigation of fixed-point card construction that is not enough for the original investigation point can accomplish the task under the new standard with quality and quantity. At the same time, it provides reference and reliable experience for the disaster investigation work in counties (cities) in the same batch and even in the whole country.
