【摘要】：隨著國民經(jīng)濟(jì)的迅速發(fā)展，地下管道作為氣體、液體的運(yùn)輸工具得到廣泛的應(yīng)用，它的正常工作與否直接關(guān)系到現(xiàn)代化工業(yè)生產(chǎn)和城鎮(zhèn)居民的正常生活。地震災(zāi)害來臨時(shí)，造成跨斷層埋地管道破壞的主要原因之一就是斷層的錯(cuò)動(dòng)，基于此情況，本文研究跨斷層埋地管道與土體間的作用是十分必要的。 首先，，本文第一章闡述課題選擇背景及意義，列舉國內(nèi)外穿越斷層埋地管道分析研究狀況，分析跨斷層管道的破壞機(jī)理及主要因素，進(jìn)而提出跨斷層埋地管道有待解決的問題。 其次，利用ADINA軟件將跨斷層埋地管道的力學(xué)分析模型進(jìn)行有限元實(shí)現(xiàn)，通過設(shè)定單元生死進(jìn)行數(shù)值模擬，建立新型土彈簧埋地管道模型，并將單壓彈簧模型與拉壓彈簧模型以及實(shí)體土模型進(jìn)行對(duì)比分析。 最后，基于單壓彈簧模型，研究分析管徑、管壁厚度、管道埋深、埋設(shè)場(chǎng)地，斷層錯(cuò)距等參數(shù)對(duì)埋地管道的影響。
[Abstract]:With the rapid development of the national economy, underground pipelines as gas and liquid transportation tools have been widely used. Its normal operation is directly related to modern industrial production and the normal life of urban residents. When earthquake disaster comes, one of the main causes of pipeline failure across faults is fault dislocation. Based on this situation, it is necessary to study the interaction between buried pipeline and soil. First of all, the first chapter describes the background and significance of the subject selection, enumerates the domestic and foreign research status of pipeline analysis through fault buried, analyzes the failure mechanism and main factors of cross-fault pipeline, and then puts forward the problems to be solved for cross-fault buried pipeline. Secondly, using Adina software, the mechanical analysis model of buried pipeline across faults is realized by finite element method, and a new model of buried pipeline with soil spring is established by numerical simulation of life and death of the set element. The single-pressure spring model, tension-compression spring model and solid soil model are compared and analyzed. Finally, based on the single pressure spring model, the influence of pipe diameter, pipe wall thickness, buried depth, buried site, fault offset and other parameters on buried pipeline is studied.
