【正文】 而各個煉廠的液化石油氣體儲存能力有限，因此液化石油氣體儲庫對于煉廠的安全健康運營有重要的意義。而儲庫的類型則由一開始的地上儲庫逐漸轉(zhuǎn)向地下。 cavern stability was evaluated again divided into global and local for the overall stability of surrounding rock stress reuse stability analysis of distribution methods, according to the redistribution of surrounding rock stress calculations or experimental results, obtained in the maximum tensile stress of surrounding rock or pressive stress to tensile or pressive strength with rock pared to evaluate the rock stability, while the local stability analysis of the use of block theory, is divided into two kinds of vaults and walls were evaluated。s energy development, but since it is underground, and its surrounding rock stability and support design engineering has bee the key technology. Underground gas storage stability of surrounding rock is directly related to the normal use of gas storage project, is a problem worthy of study and discussion. This study is a crude Huangdao underground cavern stability evaluation library. The first is the theoretical preparation for crude oil underground repository caverns are introduced。 關(guān)鍵詞 ：穩(wěn)定性評價、塊體理論、平衡拱、圍巖壓力、支護 ABSTRACT Liquefied petroleum gas as a clean energy source, but also a Grade flammable chemicals, liquefied petroleum gas underground storage is the use of underground caverns and seal technology to store liquefied petroleum gas, a safe, economical, large reserves advantages. LPG underground storage is the future direction of development of energy storage, in a foreign country has dozens of types of underground oil and gas reservoirs, and our pilot study is currently being liquefied petroleum gas underground storage of various technologies. Underground engineering has bee the development trend of social geotechnical engineering, engineering and construction of many large space on the ground is not only a waste of land resources, but there is a big security risk. Since the development of China39。 本文研究的是黃島某原油地下庫洞室圍巖穩(wěn)定性評價。地下儲氣庫就是我國能源發(fā)展的必然結(jié)果 ,而既然是地下工程 ,其圍巖的穩(wěn)定性及其支護設(shè)計便成為了工程的關(guān)鍵技術(shù)。地下工程已經(jīng)成為當(dāng)今社會巖土工程發(fā)展的趨勢 ,許多大型的工程建筑在地上空間不僅浪費土地資源 ,而且存在著較大 的安全隱患。 本科畢業(yè)論文（設(shè)計） 題 目： 黃島某原油地下庫洞室圍巖穩(wěn)定性評價 摘要 石油液化氣既是一種清潔能源 ,又是甲級易燃易爆化學(xué)品 , 石油液化氣地下儲庫是利用地下洞室及水封技術(shù)來儲存液化氣 ,具有安全、經(jīng)濟、儲量大的優(yōu)點。地下儲庫也是未來石油氣能源儲存的發(fā)展方向 ,在國外已有幾十座各類地下油氣儲庫 ,而我國目前正在試驗研究石油液化氣地下儲庫的各項技術(shù)。由于我國能源的發(fā)展需求 ,地下工程也必將在能源工程中得到大力的發(fā)展。地下儲氣庫圍巖的穩(wěn)定性問題直接關(guān)系到儲氣庫工程的正常使用 ,是一個值得研究和探討的問題。首先是理論準(zhǔn)備，對原油地下庫洞室進行介紹；然后對所在地區(qū)的地質(zhì)情況進行了介紹；再次對洞室穩(wěn)定性進行評價，分為整體和局部進行，整體穩(wěn)定性利用圍巖的應(yīng)力重分布的方法進行穩(wěn)定性分析，根據(jù)圍巖重分布應(yīng) 力計算或?qū)崪y結(jié)果，求出圍巖中的最大拉應(yīng)力或壓應(yīng)力，將其與巖體的抗拉或抗壓強度比較，來評價圍巖的穩(wěn)定性，而局部穩(wěn)定性利用塊體理論進行分析，又分為拱頂和側(cè)壁兩種分別進行評價；最后利用平衡拱理論算出圍巖壓力，然后以圍巖壓力作為參考，計算出錨桿面積，從而給出支護建議。s energy needs, underground works will also be vigorously in the energy project development. Underground gas storage is the inevitable result of China39。 Then geological region were introduced。 finally calculated using a balanced rock pressure arch theory, and then rock pressure as a reference to calculate the anchor bar area, which gives support remendations.
