【摘要】 随着我国基础设施建设的高速发展,公路交通事业取得了巨大成就,然而在公路建设过程中,出现了大量的边坡病害,为了预防边坡病害所带来的损失,必须对其实施变形监测。 论文从边坡地表变形监测、边坡深部位移监测、地下水监测、边坡应力监测、边坡支挡结构监测等方面的分析入手,详细阐述了高等级公路高边坡的监测方法,本文通过分析认为应以边坡位移监测为主。在此基础上,研究了GPS技术在边坡变形监测中的应用,同时采用灰色系统理论、人工神经网络方法对监测数据进行处理,并对监测点的变形趋势进行预测。 最后,作者用VB开发具有面向对象风格和可视化特征的边坡变形监测数据管理系统。该系统主要实现了以下功能: (1)数据维护,如数据输入、修改、删除。 (2)测点查询,可按日期和观测人员对测点进行查询。 (3)图形绘制,根据变形监测的成果,可以绘制相应的测点下沉过程、下沉速度、水平变形、水平变形速度等曲线。 (4)报表打印,如数据报表和图形报表打印。更多还原

【Abstract】 With high speed development of domestic foundation construction, road traffic project obtains great achievement. However, there are abundance of slope diseases, which caused a great deal of loss, we must carry out deformation monitoring to prevent those diseases.The paper start with analysis of slope surface deformation monitoring slope deep displacement monitoring groundwater monitoring slope stress monitoring and slope configuration monitoring, it states the method of road slope monitoring detail. The author draw a conclusion that we should concertrate on slope displacement monitoring in this paper, on the basis of this conclusion, author studied the application of GPS in slope deformation monitoring, meanwhile, it used GM ANN to process the data, and predict the deformation trend of some observation point.In the end, author worked out the management data system of slope monitoring, the system which aim to the character of object and vision mainly realized the below function:(1) Data maintenancing, data input amend delete.(2) Observation point querying, observation point can be queried by the date and surveyor.(3) Graph protracting, it can draw corresponding deformation curve of sinking process sinking speed horizontal deformation horizontal deformation speed.(4) Report printing, data and graph report printing.更多还原
