【摘要】：西氣東輸管道作為我國(guó)距離最長(zhǎng)、口徑最大的輸氣管道,管道沿線地形地貌、水文地質(zhì)條件復(fù)雜,加上人類的經(jīng)濟(jì)工程活動(dòng),導(dǎo)致了管道沿線地區(qū)環(huán)境及地質(zhì)災(zāi)害的發(fā)育。西氣東輸管道沿途的環(huán)境地質(zhì)災(zāi)害種類多、成因復(fù)雜、范圍廣,導(dǎo)致的管道事故又極易誘發(fā)嚴(yán)重的次生災(zāi)害,其直接和間接損失往往比其他類別的事故更大。在西氣東輸管道的環(huán)境及地質(zhì)災(zāi)害中,水毀災(zāi)害是經(jīng)濟(jì)損失最嚴(yán)重、人口傷亡最多和社會(huì)影響最大的自然災(zāi)害之一。統(tǒng)計(jì)表明在西氣東輸管道沿線地區(qū)發(fā)生的環(huán)境地質(zhì)災(zāi)害中,水毀災(zāi)害是發(fā)生最頻繁的環(huán)境地質(zhì)災(zāi)害。西氣東輸管道工程多年來(lái)進(jìn)行的水毀災(zāi)害風(fēng)險(xiǎn)管理工作取得了一定的防災(zāi)減災(zāi)效果,但是未能對(duì)其“投入——產(chǎn)出”進(jìn)行評(píng)估,因此對(duì)西氣東輸管道開(kāi)展水毀災(zāi)害風(fēng)險(xiǎn)管理效能評(píng)估的研究,對(duì)西氣東輸管道經(jīng)濟(jì)合理的安全、平穩(wěn)運(yùn)行具有重要的意義。 本文通過(guò)調(diào)查分析水毀災(zāi)害風(fēng)險(xiǎn)管理的國(guó)內(nèi)外研究現(xiàn)狀、國(guó)內(nèi)外效能評(píng)價(jià)開(kāi)展情況,并收集、整理西氣東輸管道水毀災(zāi)害現(xiàn)場(chǎng)資料。闡述了水毀災(zāi)害對(duì)西氣東輸管道的危害及三種常用防治措施：坡面防護(hù)、沖刷防護(hù)、支擋防護(hù)。通過(guò)介紹效能評(píng)估流程來(lái)確定西氣東輸管道水毀災(zāi)害風(fēng)險(xiǎn)管理效能評(píng)估流程。本文研究了西氣東輸管道水毀災(zāi)害風(fēng)險(xiǎn)管理的效能影響因素,并提出西氣東輸管道水毀災(zāi)害風(fēng)險(xiǎn)管理效能評(píng)估模式采用“多投入——多產(chǎn)出”的效能評(píng)估模式,投入指標(biāo)包括風(fēng)險(xiǎn)辨識(shí)的投資、風(fēng)險(xiǎn)評(píng)估的投資、風(fēng)險(xiǎn)控制的投資,產(chǎn)出指標(biāo)為對(duì)應(yīng)的風(fēng)險(xiǎn)辨識(shí)的有效性、風(fēng)險(xiǎn)評(píng)估的有效性、風(fēng)險(xiǎn)控制的有效性,在效能評(píng)估模式的基礎(chǔ)上得出效能評(píng)估模型并繼而得出效能評(píng)估指標(biāo)體系。本文通過(guò)對(duì)比分析效能評(píng)估方法,最終采用適用于“多投入——多產(chǎn)出”效能評(píng)估模式的數(shù)據(jù)包絡(luò)分析法(DEA)對(duì)西氣東輸管道水毀災(zāi)害風(fēng)險(xiǎn)管理進(jìn)行效能評(píng)估。最后本文分別對(duì)坡面水毀、河溝道水毀、臺(tái)田地水毀各選取了12處典型災(zāi)害點(diǎn)進(jìn)行了水毀災(zāi)害風(fēng)險(xiǎn)管理的效能評(píng)估,評(píng)估結(jié)果符合西氣東輸管道水毀災(zāi)害風(fēng)險(xiǎn)管理現(xiàn)狀。 本文通過(guò)對(duì)西氣東輸管道水毀災(zāi)害風(fēng)險(xiǎn)管理的效能評(píng)估,改進(jìn)管理手段,提高管理效率,達(dá)到了節(jié)約資金、提高西氣東輸管道系統(tǒng)安全性的目的。
[Abstract]:As the longest distance and the largest caliber gas pipeline in our country, the pipeline along the pipeline is characterized by topography and geomorphology, complicated hydrogeological conditions and human economic engineering activities, which lead to the development of environmental and geological disasters along the pipeline. There are many kinds of environmental geological disasters along the way of West-to-East Gas Pipeline, the causes are complex and the scope is wide, the pipeline accidents are easy to induce serious secondary disasters, and the direct and indirect losses are often greater than other types of accidents. Among the environmental and geological disasters of gas pipeline from west to east, the disaster of water destruction is one of the natural disasters with the most serious economic losses, the most casualties of the population and the greatest social impact. Statistics show that the water damage is the most frequent environmental geological hazard in the area along the pipeline from west to east. The disaster risk management work of the West to East Gas Pipeline Project for many years has achieved a certain effect of disaster prevention and mitigation, but has not been able to evaluate its "input-output". Therefore, it is of great significance to evaluate the effectiveness of water disaster risk management for the pipeline from the west to the east, which is of great significance to the economic and reasonable safety and smooth operation of the gas pipeline from the west to the east. Based on the investigation and analysis of domestic and international research status of flood disaster risk management and the development of efficiency evaluation at home and abroad, this paper collects and collates the field data of waterlogging disaster of gas pipeline from west to east. This paper expounds the damage of water disaster to the pipeline of gas transmission from west to east and three kinds of commonly used prevention measures: slope protection, scour protection and support protection. This paper introduces the efficiency evaluation process to determine the effectiveness evaluation process of water disaster risk management for the west-to-east gas pipeline. In this paper, the effect factors of water disaster risk management in West-East gas pipeline are studied, and the effectiveness evaluation model of "multi-input-multi-output" is put forward to evaluate the effectiveness of waterlogging disaster risk management in West-to-East gas pipeline. Input indicators include investment in risk identification, investment in risk assessment, investment in risk control, effectiveness of risk identification in output indicators, effectiveness of risk assessment, effectiveness of risk control, On the basis of the efficiency evaluation model, the effectiveness evaluation model and the efficiency evaluation index system are obtained. In this paper, by comparing and analyzing the effectiveness evaluation method, the data Envelopment Analysis method (DEAA), which is suitable for "multi-input-multi-output" efficiency evaluation model, is used to evaluate the effectiveness of the disaster risk management of the West to East Gas Pipeline. Finally, this paper selects 12 typical disaster sites to evaluate the effectiveness of flood risk management for slope, channel and terrace, respectively, and the results are in line with the present situation of disaster risk management in the pipeline of gas from west to east. In this paper, the effectiveness evaluation of water disaster risk management of West-to-East Gas Pipeline is presented, the management means are improved, the management efficiency is improved, the funds are saved and the safety of the West-to-East Gas Pipeline system is improved.
