【摘要】：自然界中存在著各種各樣的變形,通常而言這些變形是安全的,但是當(dāng)這些變形超過了一定的閾值時就可能會發(fā)生巨大的災(zāi)難,給人類社會造成巨大的經(jīng)濟(jì)損失。在基坑建設(shè)過程中,由于工程建設(shè)的長期性、復(fù)雜性和不穩(wěn)定性,極有可能發(fā)生變形超限的情況,造成嚴(yán)重的后果。因此為了減少或避免這種情況的發(fā)生,有必要在基坑開挖過程中對基坑實施全程的變形監(jiān)測。 本論文是以“寧波站改建工程變形監(jiān)測”為基礎(chǔ)而展開的研究。論文通過對變形監(jiān)測相關(guān)理論和WebGIS、RIA等相關(guān)技術(shù)的研究,結(jié)合ArcGIS Server探索將WebGIS應(yīng)用于變形監(jiān)測的技術(shù)路線和方法,并在此基礎(chǔ)上構(gòu)建了一個基于RIA的變形監(jiān)測WebGIS系統(tǒng)。主要研究內(nèi)容及研究成果如下： (1)對變形監(jiān)測相關(guān)理論進(jìn)行了研究,包括變形監(jiān)測的內(nèi)容和實施,主要包括水平位移監(jiān)測、沉降監(jiān)測和支撐軸力監(jiān)測,研究了國內(nèi)外變形監(jiān)測與GIS相結(jié)合的實例,并闡述了在寧波站改建工程中的監(jiān)測點(diǎn)的監(jiān)測內(nèi)容； (2)對WebGIS技術(shù)理論進(jìn)行了闡述,包括WebGIS的技術(shù)原理、特點(diǎn)、關(guān)鍵技術(shù)和實現(xiàn)方法,對比了RIA和傳統(tǒng)Web應(yīng)用,以及不同的RIA技術(shù)之間的區(qū)別與特點(diǎn),介紹了Rest架構(gòu)的特點(diǎn)、實現(xiàn)過程并通過ArcGIS Rest API進(jìn)行了實例說明； (3)對系統(tǒng)進(jìn)行了設(shè)計,包括系統(tǒng)總體設(shè)計、數(shù)據(jù)庫設(shè)計和功能設(shè)計,并針對數(shù)據(jù)導(dǎo)入模塊、GIS功能模塊和數(shù)據(jù)分析模塊進(jìn)行了開發(fā),通過灰色模型GM(1,1)進(jìn)行了數(shù)據(jù)模擬和顯示。 (4)通過ArcGIS Server、ArcGIS API For JavaScript開發(fā)了基于RIA的變形監(jiān)測WebGIS系統(tǒng),通過系統(tǒng)實現(xiàn)了對監(jiān)測數(shù)據(jù)的綜合管理,實現(xiàn)了監(jiān)測點(diǎn)的查詢分析和預(yù)警自動化。并提供了對比分析和預(yù)測分析功能。
[Abstract]:There are all kinds of deformations in nature, which are generally safe, but when they exceed a certain threshold, they can be catastrophic. In the process of foundation pit construction, due to the long-term nature, complexity and instability of the construction of the project, it is very likely that the deformation will exceed the limit. Therefore, in order to reduce or avoid the occurrence of this situation, it is necessary to carry out deformation monitoring during the excavation of foundation pit. This paper is based on "deformation monitoring of Ningbo station reconstruction project". Through the research of relevant theories of deformation monitoring and WebGISRIA, combining with ArcGIS Server, this paper explores the technical route and method of applying WebGIS to deformation monitoring. On this basis, a deformation monitoring WebGIS system based on RIA is constructed. The main research contents and results are as follows:. 1) the relevant theories of deformation monitoring are studied, including the content and implementation of deformation monitoring, including horizontal displacement monitoring, settlement monitoring and supporting axial force monitoring. Examples of combining deformation monitoring with GIS at home and abroad are studied. The monitoring contents of the monitoring points in the reconstruction project of Ningbo Station are expounded. This paper expounds the theory of WebGIS technology, including the technical principle, characteristics, key technologies and implementation methods of WebGIS, compares the application of RIA and traditional Web, and the differences and characteristics between different RIA technologies, and introduces the characteristics of Rest architecture. The implementation process is illustrated by ArcGIS Rest API. 3) the system is designed, including the system overall design, the database design and the function design. The GIS function module and the data analysis module of the data import module are developed, and the data simulation and display are carried out through the grey model GM-1). 4) the deformation monitoring WebGIS system based on RIA is developed through ArcGIS Server ArcGIS API For JavaScript. The comprehensive management of monitoring data is realized through the system, and the query analysis and early warning automation of monitoring points are realized, and the functions of contrast analysis and prediction analysis are provided.
