【摘要】：我國(guó)是世界上地質(zhì)災(zāi)害最嚴(yán)重的國(guó)家之一,其中尤以滑坡危害問(wèn)題比較突出。隨著我國(guó)經(jīng)濟(jì)社會(huì)的發(fā)展,越來(lái)越多的經(jīng)濟(jì)活動(dòng)在山區(qū)展開,比如開礦、修路、建壩、建房等,因此也帶來(lái)大量以滑坡災(zāi)害為主的地質(zhì)災(zāi)害問(wèn)題�；聻�(zāi)害不僅給我國(guó)經(jīng)濟(jì)建設(shè)帶來(lái)了巨大影響,同時(shí)也給人們的生命財(cái)產(chǎn)造成了嚴(yán)重?fù)p失。因而,對(duì)滑坡防治的研究就具有非常重要的現(xiàn)實(shí)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(yīng)用。只是抗滑樁在設(shè)計(jì)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(shí)也由于對(duì)抗滑樁缺乏長(zhǎng)期的現(xiàn)場(chǎng)監(jiān)測(cè),對(duì)抗滑樁的受力狀態(tài)并未全面了解,這就導(dǎo)致抗滑樁設(shè)計(jì)往往偏于保守以致浪費(fèi)。那么,該如何設(shè)計(jì)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(shì),又如何才能對(duì)抗滑樁潛在危險(xiǎn)提前預(yù)警,防患于未然。本文擬針對(duì)上述問(wèn)題,采用.NET開發(fā)平臺(tái)搭建系統(tǒng)主要功能框架,結(jié)合SQL Server 2005數(shù)據(jù)庫(kù)功能,運(yùn)用C#編程語(yǔ)言編寫功能實(shí)現(xiàn)代碼,初步完成了基于多通道動(dòng)態(tài)測(cè)試技術(shù)的抗滑樁監(jiān)測(cè)評(píng)價(jià)系統(tǒng)。論文主要的研究?jī)?nèi)容及相關(guān)結(jié)論如下:①基于抗滑樁設(shè)計(jì)理論及系統(tǒng)設(shè)計(jì)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(cè)分析、監(jiān)測(cè)預(yù)警、綜合評(píng)價(jià)等部分,并完成系統(tǒng)交互界面設(shè)計(jì)工作。②建立多通道動(dòng)態(tài)數(shù)據(jù)采集系統(tǒng),實(shí)現(xiàn)實(shí)時(shí)動(dòng)態(tài)監(jiān)測(cè)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(yīng)力變化等。③建立抗滑樁監(jiān)測(cè)分析模塊、預(yù)測(cè)預(yù)警模塊以及綜合評(píng)價(jià)模塊。監(jiān)測(cè)分析,實(shí)現(xiàn)動(dòng)態(tài)獲取抗滑樁監(jiān)測(cè)數(shù)據(jù),繪制抗滑樁監(jiān)測(cè)數(shù)據(jù)列表圖、波形圖、柱狀圖,便于用戶觀看查詢;預(yù)測(cè)預(yù)警,針對(duì)抗滑樁樁頂位移選擇合適的預(yù)測(cè)模型進(jìn)行預(yù)測(cè),有利于用戶了解抗滑受力變形趨勢(shì),并能對(duì)抗滑樁潛在危險(xiǎn)提前預(yù)警;綜合評(píng)價(jià),選擇合適安全性、經(jīng)濟(jì)性評(píng)價(jià)指標(biāo)對(duì)抗滑樁安全性、經(jīng)濟(jì)性進(jìn)行合理判斷,最后采用模糊綜合評(píng)價(jià)法對(duì)滑坡防護(hù)效果進(jìn)行綜合評(píng)估。④建立一整套基于多通道動(dòng)態(tài)測(cè)試技術(shù)的抗滑樁監(jiān)測(cè)評(píng)價(jià)系統(tǒng),結(jié)合實(shí)際工程,初步實(shí)現(xiàn)無(wú)人實(shí)時(shí)動(dòng)態(tài)地監(jiān)測(cè)抗滑樁的工作狀態(tài),并對(duì)抗滑樁潛在危險(xiǎn)提前警報(bào),積極響應(yīng),避免災(zāi)害進(jìn)一步發(fā)生,并對(duì)滑坡防護(hù)效果進(jìn)行綜合評(píng)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.
