【摘要】：成渝鐵路沿線地質(zhì)災(zāi)害十分發(fā)育,查清沿線既有防治工程對目前地質(zhì)災(zāi)害發(fā)展程度的適應(yīng)性以及工作區(qū)的地質(zhì)條件,掌握地質(zhì)災(zāi)害在沿線的分布情況、目前的發(fā)展情況及所處的階段,在此基礎(chǔ)上判斷災(zāi)害的發(fā)展趨勢,這對改善沿線行車安全環(huán)境和主要地質(zhì)災(zāi)害治理都具有積極的意義。由于成渝鐵路所處地區(qū)雨量充沛、軟弱巖層居多、地質(zhì)構(gòu)造復(fù)雜,各類地質(zhì)災(zāi)害均有發(fā)育,對線路運(yùn)營構(gòu)成威脅,因此對沿線災(zāi)害進(jìn)行危險(xiǎn)性評估是非常必要的。文章針對成渝鐵路(K380-K460段)采用現(xiàn)場調(diào)查與數(shù)據(jù)分析相結(jié)合,調(diào)查該線的地質(zhì)條件、地質(zhì)災(zāi)害的種類及沿線的發(fā)展情況、對鐵路建筑造成的威脅情況、它們的發(fā)展趨勢,應(yīng)用綜合指數(shù)法和模糊綜合評判法對地質(zhì)災(zāi)害的危險(xiǎn)性等級(jí)進(jìn)行評估,同時(shí)根據(jù)評估結(jié)果,結(jié)合成渝線主要地質(zhì)災(zāi)害既有防治工程對當(dāng)前災(zāi)害發(fā)展程度的適應(yīng)性,提出了沿線主要地質(zhì)災(zāi)害的整治措施和防護(hù)等級(jí)。根據(jù)現(xiàn)場的調(diào)查數(shù)據(jù)的分析,并將分析的結(jié)果與實(shí)際的經(jīng)驗(yàn)判定的結(jié)果進(jìn)行對比,驗(yàn)證所用危險(xiǎn)性評估方法的適用性與可靠性,不僅對成渝線的災(zāi)害防治提出了建議措施,也為其它鐵路線路災(zāi)害的防治提供了經(jīng)驗(yàn),對鐵路線路的運(yùn)營和維護(hù)都起到了很好的借鑒作用。文章在應(yīng)用綜合指數(shù)法和模糊綜合評判法進(jìn)行危險(xiǎn)性評估過程中,對評價(jià)因子的選擇,主要是根據(jù)地質(zhì)災(zāi)害的影響因素來確定的,在涉及每個(gè)評價(jià)因子的選擇辦法以及相應(yīng)權(quán)重的確定都是本課題研究的重點(diǎn)。在對現(xiàn)場進(jìn)行調(diào)查研究的基礎(chǔ)上結(jié)合沿線災(zāi)害的具體情況對各工點(diǎn)災(zāi)害進(jìn)行了危險(xiǎn)性評價(jià),劃分其危險(xiǎn)性分級(jí),并對災(zāi)害的發(fā)展趨勢做出了判斷。在對既有防治措施對災(zāi)害的影響的分析基礎(chǔ)上,提出沿線現(xiàn)有災(zāi)害防護(hù)的有效性、災(zāi)害的防護(hù)等級(jí)以及防護(hù)措施的建議,為成渝線地質(zhì)災(zāi)害的防治提供了定量化的科學(xué)依據(jù)。同時(shí)對類似的鐵路線路也提供了經(jīng)驗(yàn),為鐵路線路的安全運(yùn)營起到應(yīng)有的作用。
[Abstract]:The geological hazards along the Chengdu-Chongqing railway line are well developed. The adaptability of the existing prevention and control projects along the lines to the present degree of development of geological disasters and the geological conditions of the working areas are investigated, and the distribution of geological disasters along the lines is grasped.On the basis of the present development situation and the stage in which it is located, it is of positive significance to judge the development trend of the disaster, which is of great significance for improving the safety environment of the traffic along the road and the management of the main geological hazards.Due to abundant rainfall, weak rock strata, complex geological structure and various geological hazards, the Chengdu-Chongqing Railway is a threat to the operation of the railway line, so it is necessary to carry out the hazard assessment along the line.According to section K380-K460 of Chengdu-Chongqing Railway, the paper combines field investigation with data analysis to investigate the geological conditions, types of geological hazards and the development along the railway line, the threat to railway construction, and their development trend.The comprehensive index method and fuzzy comprehensive evaluation method are used to evaluate the hazard grade of geological hazards. According to the evaluation results, combined with the adaptability of the main geological hazards in Chengdu-Chongqing line to the current disaster development degree,The measures and protection grades of main geological hazards along the route are put forward.According to the analysis of the investigation data on the spot and the comparison between the results of the analysis and the actual experience, the applicability and reliability of the hazard assessment method used are verified. Not only the disaster prevention and control measures of Chengdu-Chongqing Railway are put forward, but also some suggestions are put forward for the prevention and treatment of disasters in the Chengdu-Chongqing Railway Line.It also provides experience for the prevention and treatment of other railway line disasters, and plays a good role in the operation and maintenance of railway lines.In the process of risk assessment by comprehensive index method and fuzzy comprehensive evaluation method, the selection of evaluation factors is mainly determined according to the influencing factors of geological hazards.The selection method of each evaluation factor and the determination of the corresponding weight are the focus of this research.On the basis of the investigation and study on the site, the hazard assessment of each work point disaster is carried out in combination with the specific situation of the disaster along the route, the hazard classification is divided, and the development trend of the disaster is judged.Based on the analysis of the influence of existing prevention measures on disasters, this paper puts forward the effectiveness of existing disaster protection along the route, the protection grade of disasters and the suggestions of protection measures, which provides a quantitative scientific basis for the prevention and control of geological disasters along the Chengdu-Chongqing Railway Line.At the same time, it also provides experience for similar railway lines, which plays an important role in the safe operation of railway lines.
