平原岗丘为主的地区如何开展1/5万地质灾害地面调查工作——以江西省新干县为例

HOW TO CARRY OUT THE GROUND SURVEY WORK OF 1/50000 GEOLOGICAL DISASTERS IN PLAIN HILLOCK DOMINATED AREAS——TAKE THE XINGAN COUNTY OF JIANGXI PROVICE AS AN EXAMPLE

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 Launch of the survey work of 1/50 000 geological disasters by stages and in batches, and the continuing accumulated experiences, the related specifications and provisions update gradually,and tends to be more refinement and standardized. As one of the counties（cities） which were assigned missions in the batch, at the same time, the earliest county that started up the servy work ,the entire county gives priority to plain hillock geo- morphology, and geological disasters that caused by human engineering activities and formed naturally are not many. This article is focuses on analyzing and summarizing survey methods and technical highlights of Xingan county＇s ground survey and building cards , so that ground surveys and building cards , originally whose survey points are not enough , can com- plete the task, under the new specifications, and guarantee both quality and quantity. At thesame time, it is to use {or reference and provide reliable experiences for disaster survey work of those counties （cities） in the same batch, and those with similar circumstances nation- wide.
