【摘要】：近幾十年來(lái)，政府相關(guān)部門(mén)投入了大量的人力物力及財(cái)力，加強(qiáng)對(duì)地面沉降的監(jiān)測(cè)，包括精密水準(zhǔn)測(cè)量、地下水動(dòng)態(tài)監(jiān)測(cè)、GPS實(shí)時(shí)觀測(cè)、分層標(biāo)自動(dòng)監(jiān)測(cè)等，積累了大量的數(shù)據(jù)和資料，如何合理有效的管理、分析及利用這些數(shù)據(jù)，從中提取地面沉降相關(guān)信息，使其得到更好的應(yīng)用，是擺在地面沉降控制與防治工作者面前的重要課題。 本研究依托《全國(guó)地面沉降監(jiān)測(cè)與防治綜合研究與信息系統(tǒng)建設(shè)》項(xiàng)目，根據(jù)已有的地面沉降資料、地面沉降觀測(cè)設(shè)施和動(dòng)態(tài)監(jiān)測(cè)數(shù)據(jù)相關(guān)資料，利用GIS技術(shù)和數(shù)據(jù)庫(kù)管理系統(tǒng)，對(duì)地面沉降監(jiān)測(cè)數(shù)據(jù)進(jìn)行科學(xué)規(guī)范的管理，建立動(dòng)態(tài)的地面沉降數(shù)據(jù)庫(kù)，為地面沉降災(zāi)害管理信息系統(tǒng)提供數(shù)據(jù)支撐，并為城市規(guī)劃、建設(shè)及地面沉降的防治工作等提供及時(shí)準(zhǔn)確的信息。 論文取得以下研究成果： 1）對(duì)多源數(shù)據(jù)進(jìn)行分類(lèi)。論文根據(jù)應(yīng)用需求及數(shù)據(jù)信息的不同，對(duì)所采集的信息進(jìn)行歸類(lèi)，對(duì)數(shù)據(jù)庫(kù)進(jìn)行規(guī)劃。地面沉降數(shù)據(jù)按照工作進(jìn)程劃分為調(diào)查、鉆探和槽探、監(jiān)測(cè)三類(lèi)數(shù)據(jù)。 2）建立統(tǒng)一編碼體系。在分析地面沉降多源數(shù)據(jù)特點(diǎn)及實(shí)際應(yīng)用需求的基礎(chǔ)上，建立了統(tǒng)一的編碼體系對(duì)數(shù)據(jù)進(jìn)行管理，確保各類(lèi)監(jiān)測(cè)點(diǎn)、調(diào)查點(diǎn)的唯一性，避免數(shù)據(jù)冗余，以便于統(tǒng)一協(xié)調(diào)管理和查詢。 3）完成數(shù)據(jù)字典設(shè)計(jì)。地面沉降數(shù)據(jù)采集系統(tǒng)屬性數(shù)據(jù)庫(kù)基于數(shù)據(jù)字典生成，數(shù)據(jù)字典的設(shè)計(jì)使屬性數(shù)據(jù)庫(kù)生成更加靈活，增強(qiáng)了地面沉降采集系統(tǒng)實(shí)現(xiàn)的靈活性和高效性。數(shù)據(jù)字典包含屬性數(shù)據(jù)庫(kù)中所有屬性表及各屬性表的數(shù)據(jù)項(xiàng)，保證各屬性表中相同數(shù)據(jù)項(xiàng)及數(shù)據(jù)項(xiàng)代碼的唯一性，消除數(shù)據(jù)冗余；同時(shí)數(shù)據(jù)字典的設(shè)計(jì)減少了系統(tǒng)開(kāi)發(fā)的工作量，系統(tǒng)設(shè)計(jì)與開(kāi)發(fā)不會(huì)受制于數(shù)據(jù)庫(kù)，亦無(wú)需因數(shù)據(jù)庫(kù)設(shè)計(jì)的改變而重新設(shè)計(jì)與開(kāi)發(fā)。
[Abstract]:In recent decades, the relevant government departments have invested a great deal of manpower, material and financial resources to strengthen the monitoring of land subsidence, including precision leveling, dynamic monitoring of groundwater and GPS real-time observation, automatic monitoring of stratified marks, etc. Accumulated a lot of data and data, how to reasonably and effectively manage, analyze and use these data, extract the relevant information of land subsidence, so that it can be applied better. It is an important subject in front of land subsidence control and prevention workers. This research relies on the project "Comprehensive Research and Information system Construction of National Land subsidence Monitoring and Prevention", according to the existing land subsidence data, land subsidence observation facilities and dynamic monitoring data related data, By using GIS technology and database management system, land subsidence monitoring data are managed scientifically and normatively, and dynamic land subsidence database is established to provide data support for land subsidence disaster management information system and urban planning. Provide timely and accurate information for construction and prevention of land subsidence. The research results are as follows:. 1) classifying the multi-source data. According to the application requirements and different data information, the paper classifies the collected information and plans the database. The land subsidence data is divided into investigation, drilling and grooving according to the working process. Monitor three types of data. 2) establishing a unified coding system. On the basis of analyzing the characteristics of land subsidence multi-source data and practical application requirements, a unified coding system is established to manage the data, to ensure the uniqueness of various monitoring points and survey points, and to avoid data redundancy. To facilitate the coordination of management and query. 3) complete the design of data dictionary. The attribute database of land subsidence data acquisition system is based on data dictionary, and the design of data dictionary makes attribute database more flexible. The data dictionary includes all the attribute tables and the data items of each attribute table in the attribute database to ensure the uniqueness of the same data items and the code of the data items in each attribute table. At the same time, the design of data dictionary reduces the workload of system development, and the system design and development will not be restricted by database, nor need to be redesigned and developed because of the change of database design.
