【摘要】：公路作為一種重要的基礎(chǔ)工程,連接著各個地區(qū),在文化交流、經(jīng)濟發(fā)展、思想進步、民族團結(jié)等方面都起著重要的作用。近年來,西南部地區(qū)經(jīng)濟高速發(fā)展,人口流動量大,能源物質(zhì)大量的輸入輸出,對各種交通運輸工程的需求量特別大,公路在其中承擔著重要的角色。西南部山區(qū)是我國公路泥石流的高發(fā)區(qū),尤其是項目所在的東川地區(qū),很多山體風化嚴重,巖層裸露,植被覆蓋率低,松松破碎物質(zhì)儲量豐富,降雨集中,多暴雨,是孕育泥石流的天堂。區(qū)域內(nèi)存在著數(shù)以百計的泥石流,其中不乏規(guī)模大、爆發(fā)頻率高、危害性嚴重的泥石流,泥石流的存在對區(qū)域內(nèi)的公路工程建設(shè)有著很大的影響。本論文依托國道G85昆明市功山至東川高速公路勘察設(shè)計項目開展研究,以邊坡防護設(shè)計為目標,從研究泥石流入手。在公路設(shè)計階段,結(jié)合公路工程線位和穿越方式,進行邊坡防護設(shè)計和邊坡防護技術(shù)比選,考慮項目區(qū)域內(nèi)泥石流對公路工程的影響。首先分析項目所在區(qū)域內(nèi)泥石流的形成因素和致災(zāi)特點,總結(jié)泥石流基本分區(qū)和分布規(guī)律。然后比選國內(nèi)外現(xiàn)有的評價模型,選擇適用于本項目的模糊層次綜合評價法,根據(jù)已有資料調(diào)整參數(shù)和取值,對泥石流危險性進行評價。泥石流流量包括洪水流量和輸送攜帶的固體物質(zhì)總量,通過計算泥石流洪峰流量可以推算出一次泥石流總量,泥石流總量是進行泥石流影響范圍預(yù)測的一個重要參數(shù),可以預(yù)測出泥石流堆積區(qū)的形態(tài)。最后立足于防治一體化,結(jié)合泥石流的四種致災(zāi)模式,針對性的提出直接的防治技術(shù),并把對泥石流的防治作為間接措施,對其進行綜合治理。通過本文研究,把泥石流作為影響高速公路邊坡防護的重要因素,提出泥石流危險性和影響范圍對公路邊坡防護設(shè)計的指導(dǎo)關(guān)系,為實際工程中防護設(shè)計提供參考,并建立以公路邊坡防護為目的的防治一體化綜合方案。
[Abstract]:As an important basic project, highway connects various regions and plays an important role in cultural exchange, economic development, ideological progress, national unity and so on. In recent years, with the rapid development of economy, large population flow, large input and output of energy, the demand for various transportation projects is especially large, and the highway plays an important role in it. The southwest mountainous area is a high incidence area of highway debris flow in China, especially in Dongchuan area where the project is located. Many mountain bodies are weathered seriously, rock layers are exposed, vegetation coverage is low, pine is abundant in broken material reserves, rainfall is concentrated and heavy rain is heavy. It is a paradise for mudslides. There are hundreds of debris flows in the region, including debris flow with large scale, high frequency of eruption and serious harmfulness. The existence of debris flow has a great influence on the construction of highway projects in the region. Based on the investigation and design project of G85 Kunming highway from Gongshan to Dongchuan, this paper takes slope protection design as the goal and starts with the study of debris flow. In the stage of highway design, the slope protection design and slope protection technology are compared and selected, considering the influence of debris flow in the project area on highway engineering. Firstly, the forming factors and disaster-causing characteristics of debris flow in the project area are analyzed, and the basic zoning and distribution of debris flow are summarized. Then compared with the existing evaluation models at home and abroad, the fuzzy level comprehensive evaluation method, which is suitable for this project, is selected to evaluate the risk of debris flow according to the existing data and adjust the parameters and values. The flow of debris flow includes the total amount of flood discharge and solid material transported. The total amount of debris flow can be calculated by calculating the Hong Feng discharge of debris flow, and the total amount of debris flow is an important parameter to predict the influence range of debris flow. The shape of debris flow accumulation area can be predicted. Finally, based on the integration of prevention and control, combined with the four modes of debris flow, the paper puts forward the direct prevention and control technology, and takes the prevention and control of debris flow as an indirect measure to comprehensively control the debris flow. Through the research of this paper, taking debris flow as an important factor affecting highway slope protection, the paper puts forward the guiding relationship between debris flow hazard and influence scope to highway slope protection design, and provides a reference for actual engineering protection design. A comprehensive scheme of prevention and control is established for the purpose of highway slope protection.
