【正文】 、易施工的加固方法可推動加固材料的發(fā)展。 建筑工程學院畢業(yè)論文 第 22 頁 結 論 加固改造理論的提高是該 項技術發(fā)展的另一個方面。目前的加固基本上是針對構造和承載能力不足的構件，缺乏從結構總體上的把握與判別。在結構設計領域則有相應的理論，如建筑抗震設計中的概念設計，混凝土結構設計中的強柱弱梁強節(jié)點等。目前的加固有時會適得其反。例如：對多層磚混結構的某一層墻體做夾板墻加固，使得該層墻體的鋼度大幅度增加，形成與相臨樓層的鋼度差，對結構的抗震不利。此外還有加固后構件的承載能力提高，防火等級大幅度下降等問題。這些問題需要從總體上把握，靠加固理論的提高來解決。 加固改造技術的提高還體現(xiàn)在施工技術改善和提高及施工機 具上，而在這方面的研究一直相對較少。 我國建筑市場巨大，當前土建結構的加固改造是我們面臨的一項意義重大的任務。隨著建筑業(yè)的蓬勃發(fā)展，建筑物的加固、維修、改造的應用領域和范圍也將越來越廣，各種新的加固技術必將不斷地涌現(xiàn)，結構的加固技術也必將取得更長足的發(fā) 。 國內外結構工程的發(fā)展過程表明，當工程建設進行到一定階段后，工程結構的維修改造將成為主要的建設方式。我國的工程結構，特別是建筑物則因為特殊的歷史和發(fā)展方式，在許多方面更需要對既有建筑物進行加固與維修改造。建筑物加固與維修改造的前提是對其進行鑒定，然后根據(jù)鑒定 結果采取相應的加固處理措施。由于城市化進程加快，設計、施工和管理使用存在先天不足，同時由于地震、火災等災害的影響，建筑結構鑒定與加固改造已成為我國基本建設急需解決的重大問題。當前國內發(fā)展生產，提高生產力的重心，已從新建工業(yè)企業(yè)轉移到對已有企業(yè)的技術改造，以取得更大的投資效益。同樣，對民用建筑進行改造的要求，在我國也日益迫切。 建筑工程學院畢業(yè)論文 第 23 頁 致 謝 在這篇論文結束之際，再次感謝我的指導老師董成國老師。 ***為我的論文提供了許多寶貴的建議與意見，使得我的論文更加完善。在此表示深深的感謝 !在此 謹向我尊敬的導師致以崇高的敬意和誠摯的感謝 ! 建筑工程學院畢業(yè)論文 第 24 頁 參 考 文 獻 [1] 高成發(fā) .GPS 測量 [M].北京：人民交通出版社， [2] 胡伍生，高成發(fā) .GPS 測量原理與應用 [M]. 北京：人民交通出版社， [3] 萬德鈞 ,房建成 ,王慶 .GPS 動態(tài)濾波的理論、方法及其應用 [M].南京：江蘇科學技術出版社， 2021,110 [4] 劉大杰，施一民，過靜珺 .全球定位系統(tǒng)（ GPS）的原理與數(shù)據(jù)處理 [M].上海：同濟大學出版社， [5] 徐 紹全，張華海，楊志強等 .

The caravan, consisting of more than 100 camels, three horsedrawn carriages and four support vehicles, started the trip from Jingyang county in Shaanxi on Sept 19, 2021. It will pass through Gansu province and Xinjiang Uygur autonomous region, and finally arrive in Almaty, formerly known as AlmaAta, the largest city in Kazakhstan, and Dungan in Zhambyl province. The trip will cover about 15,000 kilometers and take the caravan more than one year to plete. The caravan is expected to return to Jingyang in March 2021. Then they will e back, carrying specialty products from Kazakhstan A small art troupe founded six decades ago has grown into a household name in the Inner Mongolia autonomous region. In the 1950s, Ulan Muqir Art Troupe was created by nine young musicians, who toured remote villages on horses and performed traditional Mongolian music and dances for nomadic families. The 54yearold was born in Tongliao, in eastern Inner Mongolia and joined the troupe in says there are 74 branch troupes across Inner Mongolia and actors give around 100 shows every year to local nomadic people. I can still recall the days when I toured with the troupe in the early 39。80s. We sat on the back of pickup trucks for hours. The sky was blue, and we couldn39。t help but sing the folk songs, Nasun says. The vastness of Inner Mongolia and the lack of entertainment options for people living there, made their lives lonely. The nomadic people were very excited about our visits, Nasun recalls. We didn39。t have a formal stage. The audience just sat on the grass. Usually, the performances became a big party with local people joining in. For him, the rewarding part about touring isn39。t just about sharing art with nomadic families but also about gaining inspiration for the music and dance. Ulan Muqir literally translates as red burgeon, and today39。s performers of the troupe still tour the region39。s villages and entertain nomadic families, but their fame has spread around the world. On May 16 and 17, nearly 100 singers and dancers from the troupe performed at Beijing39。s Poly Theater. Their show, titled Ulan Muqir on the Grassland, depicted the history and development of the art troupe. Being from the region allowed me to embrace the culture of Inner Mongolia and being a member of the troupe showed me where I belonged, Nasun, the art troupe39。s president, who is also a renowned tenor, tells China Daily. During a tour in 1985, he went to a village and met an elderly local man, who told him a story about his friendship with a solider from Shenyang, capital of Northeast China39。s Liaoning province, decades ago. The solider gave the old man a handmade saddle when they bid farewell. The story inspired Nasun to write Carved Saddle, a song that later became one of his most popular numbers. Now, every year, Nasun recruits young singers and dancers for the troupe. The troupe has also designed a new repertoire, which is mostly based on the daily lives of Mongolian people, especially the lives of nomadic families, and has bined contemporary musical elements with folk songs of the region. Haimu, a 25yearold khoomei (a local variant of overtone singing) singer, joined the troupe three years ago. Along with a sixmember band, he performs fast songs and soft ones that he writes－ all while playing the horsehead fiddle.Although I learned the piano since childhood and grew up listening to various kinds of music, to me, the folk music of Inner Mongolia is the root, he says. Performing in remote villages is pleasant. I feel at home on the boundless grasslands, and the warm people there make me feel fulfilled. The first round of spring auction season in Beijing ended last week, but it failed to create much spring in the art marke
