【摘要】：自然界中存在着各种各样的变形,通常而言这些变形是安全的,但是当这些变形超过了一定的阈值时就可能会发生巨大的灾难,给人类社会造成巨大的经济损失。在基坑建设过程中,由于工程建设的长期性、复杂性和不稳定性,极有可能发生变形超限的情况,造成严重的后果。因此为了减少或避免这种情况的发生,有必要在基坑开挖过程中对基坑实施全程的变形监测。本论文是以“宁波站改建工程变形监测”为基础而展开的研究。论文通过对变形监测相关理论和WebGIS、RIA等相关技术的研究,结合ArcGIS Server探索将WebGIS应用于变形监测的技术路线和方法,并在此基础上构建了一个基于RIA的变形监测WebGIS系统。主要研究内容及研究成果如下： (1)对变形监测相关理论进行了研究,包括变形监测的内容和实施,主要包括水平位移监测、沉降监测和支撑轴力监测,研究了国内外变形监测与GIS相结合的实例,并阐述了在宁波站改建工程中的监测点的监测内容； (2)对WebGIS技术理论进行了阐述,包括WebGIS的技术原理、特点、关键技术和实现方法,对比了RIA和传统Web应用,以及不同的RIA技术之间的区别与特点,介绍了Rest架构的特点、实现过程并通过ArcGIS Rest API进行了实例说明； (3)对系统进行了设计,包括系统总体设计、数据库设计和功能设计,并针对数据导入模块、GIS功能模块和数据分析模块进行了开发,通过灰色模型GM(1,1)进行了数据模拟和显示。 (4)通过ArcGIS Server、ArcGIS API For JavaScript开发了基于RIA的变形监测WebGIS系统,通过系统实现了对监测数据的综合管理,实现了监测点的查询分析和预警自动化。并提供了对比分析和预测分析功能。
[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.
