【摘要】：進(jìn)入新世紀(jì)以來,隨著我國(guó)經(jīng)濟(jì)建設(shè)的飛速發(fā)展,鐵路的建設(shè)發(fā)展也邁出了嶄新的一章。其所產(chǎn)生的鐵路振動(dòng)危害也越來越明顯。而如今,在我國(guó)內(nèi)省-省之間以及省-市之間越來越多的高速鐵路在規(guī)劃修建的時(shí)候無可避免地選擇了一些敏感的路線,這些敏感路線會(huì)穿越以及沿途涉及到一些文物古跡,振動(dòng)會(huì)對(duì)文物古跡造成無形的影響和破壞。因此基于如何有效的防護(hù)振動(dòng)這一前提,預(yù)測(cè)振動(dòng)影響就成為了新時(shí)代鐵路干線的新難題。本文所研究背景是正在規(guī)劃建設(shè)中的京張城際鐵路,根據(jù)鐵路路網(wǎng)規(guī)劃,和選線計(jì)劃需要,將會(huì)三次下穿北京八達(dá)嶺長(zhǎng)城和水關(guān)長(zhǎng)城等重點(diǎn)保護(hù)單位,鐵路的開通運(yùn)營(yíng)將不可避免地對(duì)長(zhǎng)城的保護(hù)產(chǎn)生有害影響。高速列車引起的振動(dòng)對(duì)長(zhǎng)城本體而言,是典型的動(dòng)力問題,本文采用定性分析和定量計(jì)算等方法,通過實(shí)地考察調(diào)研,開展了現(xiàn)場(chǎng)調(diào)查測(cè)試工作,利用瞬態(tài)表面波法對(duì)相關(guān)地段進(jìn)行測(cè)試,獲取地質(zhì)參數(shù)和技術(shù)指標(biāo),通過對(duì)結(jié)構(gòu)物主體進(jìn)行縱波測(cè)試,得到主體結(jié)構(gòu)物最大容許振動(dòng)速度,對(duì)長(zhǎng)城本體耐震程度進(jìn)行理論計(jì)算,獲得了列車振動(dòng)源、巖體物理力學(xué)性能以及相關(guān)地段的地質(zhì)參數(shù)資料,最后建立軌道-山體-隧道的三維模型,采用國(guó)際上通用的大型有限元?jiǎng)恿Ψ治鲕浖嗀NSYS和Universal Mechanism,進(jìn)行三維實(shí)體有限元數(shù)值分析模擬和有限元仿真模擬計(jì)算分析,研究新建北京至張家口城際列車對(duì)長(zhǎng)城本體的影響。最終根據(jù)三種不同方法的結(jié)論對(duì)比,得到鐵路選線的振動(dòng)影響結(jié)論,并提出減振措施和施工爆破建議。為了保護(hù)我國(guó)重要的文化瑰寶—長(zhǎng)城,評(píng)估京張城際列車運(yùn)行對(duì)長(zhǎng)城的影響程度,不僅是一個(gè)重要立項(xiàng)的依據(jù)之一,也為以后此類相關(guān)問題的深入研究提供理論和參考依據(jù)。
[Abstract]:In the new century, with the rapid development of China's economic construction, railway construction has also taken a new chapter. The damage caused by railway vibration is becoming more and more obvious. And today, more and more high-speed railways in our country, between provinces, cities and cities, inevitably choose sensitive routes when planning and building, and these sensitive routes will traverse and involve cultural relics and monuments along the way. Vibration will cause intangible impact and destruction on cultural relics and monuments. Therefore, based on the premise of how to protect vibration effectively, predicting the influence of vibration becomes a new difficult problem of railway trunk line in the new era. The background of this paper is the Beijing-Zhangzhou-Intercity Railway, which is under planning and construction. According to the railway network planning and the needs of the route selection plan, key protection units such as Beijing Badaling the Great Wall and Shuiguan the Great Wall will be cut down three times. The opening and operation of the railway will inevitably have harmful effects on the protection of the Great Wall. The vibration caused by high-speed train is a typical dynamic problem to the Great Wall itself. This paper adopts qualitative analysis and quantitative calculation methods, through field investigation and investigation, carries out field investigation and test work. By using the transient surface wave method to test the relevant sections, the geological parameters and technical indexes are obtained, and the maximum allowable vibration velocity of the main structure is obtained by measuring the longitudinal wave of the main body of the structure, and the degree of earthquake resistance of the main body of the Great Wall is calculated theoretically. The data of train vibration source, physical and mechanical properties of rock mass and geological parameters are obtained. Finally, a three-dimensional model of track mountain body tunnel is established. In this paper, a large-scale finite element dynamic analysis software ANSYS and Universal Mechanism are used to study the influence of the newly built Beijing-Zhangjiakou intercity train on the Great Wall body by means of three-dimensional solid finite element numerical analysis and finite element simulation calculation. Finally, according to the conclusion comparison of three different methods, the conclusion of vibration influence of railway line selection is obtained, and the vibration reduction measures and construction blasting suggestions are put forward. In order to protect the important cultural treasure of our country-the Great Wall, it is not only one of the important foundation to evaluate the influence degree of Beijing-Zhangcheng train operation on the Great Wall, but also provide theoretical and reference basis for further research on this kind of related issues.
