公路工程岩溶环境地理信息系统开发

Development of Geological Information System of Karst Environment for Highway Engineering

目前岩溶区公路工程建设和管理仍存在较大的局限性,主要表现在:(1)区域性的现势资料掌握有限;(2)公路基础资料管理落后;(3)研究成果共享不足;(4)GIS的应用有限。因此,很有必要建立公路工程岩溶环境地理信息系统,对相关数据进行可视化管理,为有关部门快速有效地提供岩溶地区公路工程建设所涉及区域性的地质环境背景信息。鉴于此,项目组以通用GIS软件为平台,以VB为工具开发了"公路工程岩溶环境地理信息系统"。系统以公路工程建设所涉及区域性的地质环境背景信息的空间图形信息和属性信息为基础建立系统数据库,包括交通网状况、岩溶地质环境背景、岩溶病害与地质灾害处置、岩溶资源利用、岩溶环境保护和岩溶环境区划等数据模块。通过直观的界面设计,简化了通用GIS软件的复杂操作模式,从而可快速有效地为公路工程岩溶环境区划、材料分布和利用、工程病害与处治、环境评价与保护等提供相关信息。

At now,there still have some limitations in construction and management of highway engineering in karst areas,which show in the following aspects：（1） limited control of regional up-to-date data;（2）out-dated management of highway elementary data;（3） insufficient share of research results;（4）limited use of GIS.As a result,for the sake of visualization management of relevant data and fast and effective provision of geological and environmental background data relate to highway engineering to relative departments in karst areas,development of geological information system of karst environment for highway engineering is necessary.Therefore,members of the project group developed geological information system of karst environment for highway engineering using general GIS as platform and VB as tool.The database is built based on the spatial data and attribute data of regional geological environmental background data relate to the construction of highway engineering,which include traffic network,karst geolo-gical environmental background,treatment to karst diseases and geological hazards,utilization of karst resources,protection of karst environment and karst environment zoning for highway.Intuitionistic interface design simplifies the complicated operating mode of General GIS software,which can effectively and efficiently provide relational data of karst environment zoning,distribution and utilization of materials,diseases and treatment and environment evaluation and protection etc.
