【摘要】：中国经济的快速发展和西部大开发的推进，包括公路在内的多种基础设施建设已进入快速发展的阶段。伴随公路工程规模加大、对线路要求增高，经常需要人为对各种高边坡进行开挖，形成了很多环境复杂、地质条件复杂和规模大的开挖工程边坡。当边坡开挖时，坡体内的地应力状态将发生很大的改变，进行重新分布，，并改变原有的平衡状态，坡体随开挖的进行将以变形的方式调整其应力分布以寻求新的平衡状态。工程实践表明，边坡的变形和稳定问题与边坡的开挖时间、边坡所在区域的气候现象、极端自然现象等因素在时间上密切相关。施工引起的应力应变、应力重新分布及变形将是一个渐变且长期的过程。因此对边坡稳定性情况进行系统监测，分析其变形特征和掌握其变形变化过程是十分必要的。对边坡进行施工期和运营期的长期跟踪监测，及时获取监测数据，通过监测数据能指导现场施工、发现边坡变形迹象、也能对边坡支护措施进行一定量的检验，尽早的发现设计和施工过程中的一些不足的地方，进而可以对施工方式进行改进或对支护方案进行调整或加固，将可能出现的灾害防患于未然，这样可以有效的减少甚至避免事故的发生。同时，监测数据能为边坡的变形情况分析和边坡的稳定性综合分析提供数据支撑。因此对边坡进行施工期及运营期安全监测具有可观的经济效益和重要的社会效益。本文通过对已有的边坡监测项目资料进行综合分析的基础上，主要进行了以下4个方面的工作：（1）概述了边坡安全监测在边坡施工期和运行期的必要性、重要性和作用；（2）总结不同监测技术手段采用的方法及仪器，综合分析各自的特点和适用范围，提出科学适合的监测方法，使监测工作既符合实际工作情况，又能尽量经济安全和实用稳定。（3）基于多种监测方式的监测数据，建立通用的数据库，利用C#编程语言和微软的SQL Server2008数据库技术对监测信息管理系统进行设计和实现，建立边坡监测信息管理系统，该系统主要实现监测数据的入库管理、监测仪器的资料管理、监测数据管理、监测数据过程线的绘制、监测数据可视化查询、数据的导入和导出及监测预警等，系统能及时从监测数据中分析出边坡相关物理量的变化情况，满足了及时反馈监测结果给参建各方的要求，符合动态设计、信息化施工的现代设计思想的要求。（4）将边坡监测中选择仪器的基本原则、多种监测仪器的特点及适用范围、边坡信息化监测方案设计原则和建立的边坡监测信息管理系统应用到实际边坡监测工程中，检验研究理论成果和研究系统的实际应用情况。
[Abstract]:With the rapid development of China's economy and the development of the western region, the construction of various infrastructure facilities, including highways, has entered a stage of rapid development. It is often necessary to excavate various kinds of high slopes, forming a lot of excavated engineering slopes with complex environment, complicated geological conditions and large scale. When the slope is excavated, the in-situ stress state of the slope will be greatly changed and redistributed. The stress distribution of slope will be adjusted by deformation in order to find a new equilibrium state. Engineering practice shows that the slope deformation and stability problems and excavation time, The climatic phenomena, extreme natural phenomena and other factors in the area where the slope is located are closely related in time. The stress redistribution and deformation will be a gradual and long-term process, so it is necessary to systematically monitor the slope stability, analyze the deformation characteristics and master the deformation change process. The long-term tracking and monitoring of the slope during the construction period and the operation period, the monitoring data can be obtained in time. Through the monitoring data, the site construction can be guided, the slope deformation can be found, and the slope support measures can also be tested in a certain amount. Find some deficiencies in the design and construction process as soon as possible, and then improve the construction methods or adjust or reinforce the support scheme, and prevent the possible disasters. This can effectively reduce or even avoid accidents. At the same time, The monitoring data can provide data support for slope deformation analysis and slope stability comprehensive analysis, so the safety monitoring of slope during construction and operation period has considerable economic benefits and important social benefits. Based on the comprehensive analysis of the existing slope monitoring project data, this paper mainly carried out the following four aspects of work:. 1) the necessity, importance and function of slope safety monitoring during the construction and operation of the slope are summarized. 2) summing up the methods and instruments used in different monitoring techniques, synthetically analyzing their respective characteristics and applicable scope, and putting forward scientific and suitable monitoring methods, so that the monitoring work can not only accord with the actual working conditions, but also be economical, safe, practical and stable as far as possible. Based on the monitoring data of various monitoring methods, the general database is established, and the monitoring information management system is designed and implemented by using C # programming language and SQL Server2008 database technology of Microsoft, and the slope monitoring information management system is established. The system mainly realizes the management of the database of the monitoring data, the data management of the monitoring instrument, the management of the monitoring data, the drawing of the monitoring data process line, the visual query of the monitoring data, the import and export of the data and the monitoring and warning, etc. The system can analyze the change of the slope related physical quantity from the monitoring data in time, and meet the requirements of timely feedback monitoring results to the parties involved in the construction, and meet the requirements of the modern design idea of dynamic design and information construction. 4) the basic principles of selecting instruments in slope monitoring, the characteristics and applicable scope of various monitoring instruments, the design principles of slope information monitoring schemes and the established slope monitoring information management system are applied to the actual slope monitoring projects. To test the theoretical results and the practical application of the research system.
