【摘要】：我國是世界上地質(zhì)災害最嚴重的國家之一,其中尤以滑坡危害問題比較突出。隨著我國經(jīng)濟社會的發(fā)展,越來越多的經(jīng)濟活動在山區(qū)展開,比如開礦、修路、建壩、建房等,因此也帶來大量以滑坡災害為主的地質(zhì)災害問題�；聻暮Σ粌H給我國經(jīng)濟建設帶來了巨大影響,同時也給人們的生命財產(chǎn)造成了嚴重損失。因而,對滑坡防治的研究就具有非常重要的現(xiàn)實意義。目前抗滑樁作為滑坡整治的主要措施之一,得到非常廣泛的應用。只是抗滑樁在設計中還存在一些不足之處,如樁身荷載不確定性及荷載分布形式不確定,同時也由于對抗滑樁缺乏長期的現(xiàn)場監(jiān)測,對抗滑樁的受力狀態(tài)并未全面了解,這就導致抗滑樁設計往往偏于保守以致浪費。那么,該如何設計才能充分發(fā)揮抗滑樁的抗滑作用,又如何才能全面了解抗滑樁受力變形趨勢,又如何才能對抗滑樁潛在危險提前預警,防患于未然。本文擬針對上述問題,采用.NET開發(fā)平臺搭建系統(tǒng)主要功能框架,結(jié)合SQL Server 2005數(shù)據(jù)庫功能,運用C#編程語言編寫功能實現(xiàn)代碼,初步完成了基于多通道動態(tài)測試技術(shù)的抗滑樁監(jiān)測評價系統(tǒng)。論文主要的研究內(nèi)容及相關(guān)結(jié)論如下:①基于抗滑樁設計理論及系統(tǒng)設計內(nèi)容的研究,初步將系統(tǒng)功能劃分為傳感器管理、監(jiān)測分析、監(jiān)測預警、綜合評價等部分,并完成系統(tǒng)交互界面設計工作。②建立多通道動態(tài)數(shù)據(jù)采集系統(tǒng),實現(xiàn)實時動態(tài)監(jiān)測抗滑樁工作狀態(tài)的功能,如樁頂位移變化、樁身位移變化、土壓力變化、鋼筋應力變化等。③建立抗滑樁監(jiān)測分析模塊、預測預警模塊以及綜合評價模塊。監(jiān)測分析,實現(xiàn)動態(tài)獲取抗滑樁監(jiān)測數(shù)據(jù),繪制抗滑樁監(jiān)測數(shù)據(jù)列表圖、波形圖、柱狀圖,便于用戶觀看查詢;預測預警,針對抗滑樁樁頂位移選擇合適的預測模型進行預測,有利于用戶了解抗滑受力變形趨勢,并能對抗滑樁潛在危險提前預警;綜合評價,選擇合適安全性、經(jīng)濟性評價指標對抗滑樁安全性、經(jīng)濟性進行合理判斷,最后采用模糊綜合評價法對滑坡防護效果進行綜合評估。④建立一整套基于多通道動態(tài)測試技術(shù)的抗滑樁監(jiān)測評價系統(tǒng),結(jié)合實際工程,初步實現(xiàn)無人實時動態(tài)地監(jiān)測抗滑樁的工作狀態(tài),并對抗滑樁潛在危險提前警報,積極響應,避免災害進一步發(fā)生,并對滑坡防護效果進行綜合評估,從而為類似滑坡治理提供借鑒。
[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.
