【摘要】：我国是世界上地质灾害最严重的国家之一,其中尤以滑坡危害问题比较突出。随着我国经济社会的发展,越来越多的经济活动在山区展开,比如开矿、修路、建坝、建房等,因此也带来大量以滑坡灾害为主的地质灾害问题。滑坡灾害不仅给我国经济建设带来了巨大影响,同时也给人们的生命财产造成了严重损失。因而,对滑坡防治的研究就具有非常重要的现实意义。目前抗滑桩作为滑坡整治的主要措施之一,得到非常广泛的应用。只是抗滑桩在设计中还存在一些不足之处,如桩身荷载不确定性及荷载分布形式不确定,同时也由于对抗滑桩缺乏长期的现场监测,对抗滑桩的受力状态并未全面了解,这就导致抗滑桩设计往往偏于保守以致浪费。那么,该如何设计才能充分发挥抗滑桩的抗滑作用,又如何才能全面了解抗滑桩受力变形趋势,又如何才能对抗滑桩潜在危险提前预警,防患于未然。本文拟针对上述问题,采用.NET开发平台搭建系统主要功能框架,结合SQL Server 2005数据库功能,运用C#编程语言编写功能实现代码,初步完成了基于多通道动态测试技术的抗滑桩监测评价系统。论文主要的研究内容及相关结论如下:①基于抗滑桩设计理论及系统设计内容的研究,初步将系统功能划分为传感器管理、监测分析、监测预警、综合评价等部分,并完成系统交互界面设计工作。②建立多通道动态数据采集系统,实现实时动态监测抗滑桩工作状态的功能,如桩顶位移变化、桩身位移变化、土压力变化、钢筋应力变化等。③建立抗滑桩监测分析模块、预测预警模块以及综合评价模块。监测分析,实现动态获取抗滑桩监测数据,绘制抗滑桩监测数据列表图、波形图、柱状图,便于用户观看查询;预测预警,针对抗滑桩桩顶位移选择合适的预测模型进行预测,有利于用户了解抗滑受力变形趋势,并能对抗滑桩潜在危险提前预警;综合评价,选择合适安全性、经济性评价指标对抗滑桩安全性、经济性进行合理判断,最后采用模糊综合评价法对滑坡防护效果进行综合评估。④建立一整套基于多通道动态测试技术的抗滑桩监测评价系统,结合实际工程,初步实现无人实时动态地监测抗滑桩的工作状态,并对抗滑桩潜在危险提前警报,积极响应,避免灾害进一步发生,并对滑坡防护效果进行综合评估,从而为类似滑坡治理提供借鉴。
[Abstract]:China is one of the most serious geological disasters in the world, especially landslide hazard. With the development of our country's economy and society, more and more economic activities are carried out in mountainous areas, such as mining, road building, dam building, building houses and so on. Landslide disaster has not only brought great influence to our country's economic construction, but also caused serious loss of people's life and property. Therefore, the study of landslide prevention has very important practical significance. At present, as one of the main measures of landslide regulation, anti-slide pile is widely used. However, there are still some deficiencies in the design of anti-slide pile, such as the uncertainty of load on pile body and the uncertainty of load distribution, and the lack of long-term on-site monitoring of anti-slide pile, so the stress state of anti-slide pile is not fully understood. As a result, the design of anti-slide pile is often conservative and wasteful. So, how to design the anti-slide pile to give full play to the anti-slide role, and how to fully understand the anti-slide pile deformation trend, and how to resist the slide pile potential danger early warning, prevention. In order to solve the above problems, this paper uses .NET development platform to build the main functional framework of the system, combined with the database function of SQL Server 2005, and uses C # programming language to write the code. The monitoring and evaluation system of anti-slide pile based on multi-channel dynamic test technology is preliminarily completed. The main research contents and related conclusions are as follows: 1 based on the research of anti-slide pile design theory and system design content, the system functions are divided into sensor management, monitoring and analysis, monitoring and early warning, comprehensive evaluation and so on. At the same time, a multi-channel dynamic data acquisition system is set up to realize the function of real-time dynamic monitoring of the working state of anti-slide pile, such as pile top displacement change, pile body displacement change and earth pressure change. The monitoring and analysis module, the forecasting and warning module and the comprehensive evaluation module of anti-slide pile are established. Monitoring and analysis, dynamic acquisition of anti-slide pile monitoring data, drawing anti-slide pile monitoring data list diagram, waveform diagram, bar chart, easy for users to view and query, prediction and early warning, for anti-slide pile top displacement selection of the appropriate prediction model for prediction, It is helpful for users to understand the tendency of anti-slide force and deformation, and to forewarn the potential danger of sliding pile in advance; to evaluate comprehensively, select appropriate safety, economic evaluation index to resist the safety of slide pile, and to make reasonable judgment on economy, Finally, a set of anti-slide pile monitoring and evaluation system based on multi-channel dynamic test technology is established by using fuzzy comprehensive evaluation method to evaluate the landslide protection effect. The preliminary realization of unmanned real-time and dynamic monitoring of the working state of anti-slide piles, and early warning of potential hazards against sliding piles, positive response to avoid further disasters, and comprehensive evaluation of landslide protection effect, Thus providing reference for similar landslide treatment.
