【摘要】：“5.12”汶川地震,使得災(zāi)區(qū)各項基礎(chǔ)建設(shè)受損嚴重,造成巨大的人員損失、經(jīng)濟損失；除此外,地震誘發(fā)了大量的地質(zhì)次生災(zāi)害。其中,山體崩塌和滑坡等直接地為泥石流發(fā)生和發(fā)展提供了松散的固體物源,可能致使流域內(nèi)發(fā)育的泥石流溝在比較長的一段時間中均處于非常活躍的時期。走馬嶺溝地理位置在綿竹市清平鄉(xiāng)鹽井村6組,綿竹市清平鄉(xiāng)銀杏溝旅游區(qū)內(nèi),為綿遠河左岸支流,曾是“5.12”汶川地震重災(zāi)區(qū)之一。大地震后,走馬嶺溝溝域內(nèi)各類地質(zhì)次生災(zāi)害頻發(fā)。2010年“8.13”走馬嶺溝特大泥石流災(zāi)害爆發(fā)后,進行了全面又大規(guī)模的泥石流災(zāi)害防治工程。但是由于地震后溝域內(nèi)松散固體物源的大大增多,每次遭到大暴雨均會引發(fā)大規(guī)模的泥石流災(zāi)害,已治理的工程有部分損毀。基于此,開展綿竹走馬嶺溝泥石流治理工程的調(diào)查及防治效果的研究,總結(jié)此類泥石流治理工程的防治方法,進一步采取對工程的補充措施是非常必要的。本文以綿竹市清平鄉(xiāng)走馬嶺溝泥石流治理工程作為例子,走馬嶺溝位屬2008年汶川特大地震帶內(nèi),在綿竹市清平鄉(xiāng)銀杏溝旅游區(qū)。2008年的特大地震不僅造成嚴重的經(jīng)濟財產(chǎn)損失,還造成了清平鄉(xiāng)不少的人員傷亡,同時地震還誘發(fā)了為數(shù)眾多的次生地質(zhì)災(zāi)害,如泥石流、滑坡、崩塌等。為盡快消除地質(zhì)災(zāi)害隱患,促進災(zāi)后恢復重建工作順利實施,2010年“8.13”走馬嶺溝特大泥石流災(zāi)害爆發(fā)后,進行了全面又大規(guī)模的泥石流災(zāi)害防治工程。走馬嶺溝泥石流工程治理采用以“攔為主、排為輔”的治理方案,工程竣工后受到強降雨的檢驗,工治理程效果得到初步顯現(xiàn)。但主體工程完成后受多次強降雨的影響,部分附屬工程結(jié)構(gòu)損壞,針對工程設(shè)計中存在的缺陷,加以了分析總結(jié),針對泥石流目前情況,重新提出了三種補充、修復方案：方案1：新建5#支溝排導槽+6#、7#壩清淤+垂裙修復+防沖墻基礎(chǔ)修復+過水路面清淤+停淤場圍堤修復+主溝壩體修復；方案2：5#壩加高+5#壩清淤+垂裙修復+防沖墻基礎(chǔ)修復+過水路面清淤+停淤場圍堤修復+主溝壩體修復；方案3：5#壩清淤+6#壩清淤+5#支溝防護堤+防沖肋坎+防沖墻基礎(chǔ)修復+過水路面清淤+停淤場圍堤修復+主溝壩體修復,上述三個方案的治理范圍不同,工程項目與規(guī)模不同,將導致防治工程數(shù)量、投資上存在一定的差別。論文最后根據(jù)現(xiàn)場治理的實際效果進行分析研究、評價以及建議措施。
[Abstract]:The "5.12" Wenchuan earthquake caused serious damage to the infrastructure in the disaster area, resulting in huge loss of personnel and economy, in addition to the earthquake induced a large number of geological secondary disasters. Among them, landslides and landslides directly provide a loose solid source for the occurrence and development of debris flow, which may lead to the development of debris flow gullies in a relatively long period of time in a very active period. The geographical location of Ma Ling ditch is in 6 groups of Yanjing Village in Qingping Township, Mianzhu City, and in Ginkgo Ginkgo ditch tourist area of Qingping Township in Mianzhu City. It is a tributary on the left bank of Mianyuan River and was once one of the hardest hit areas of Wenchuan earthquake on "5.12". After the earthquake, various kinds of geological secondary disasters occurred frequently in the Tumaling gully region. After the "8.13" Tongma Linggou debris flow disaster broke out in 2010, a comprehensive and large-scale debris flow disaster prevention project was carried out. However, due to the increase of loose solid sources in the gully region after the earthquake, every time the rainstorm will lead to a large-scale debris flow disaster, the project has been partially damaged. Based on this, it is very necessary to carry out investigation and control effect research on debris flow control project of Mianzhu Walinggou debris flow, summarize the prevention and cure method of this kind of debris flow control project, and take further supplementary measures to the project. This paper takes the project of debris flow control in Qingping Township, Mianzhu City, as an example. It belongs to the Wenchuan earthquake zone in 2008 and is located in the Ginkgo Valley tourist area of Qingping Township, Mianzhu City. The huge earthquake of 2008 not only caused serious economic and property losses, At the same time, the earthquake also induced a large number of secondary geological disasters, such as debris flow, landslide, collapse and so on. In order to eliminate the hidden dangers of geological hazards as soon as possible and promote the smooth implementation of the work of post-disaster recovery and reconstruction, a comprehensive and large-scale debris flow prevention project was carried out after the "8.13" Luoma Linggou debris flow disaster broke out in 2010. The project of mud-rock flow control in Wumaling gully adopts the control scheme of "stop as the main project, drainage as auxiliary". After the completion of the project, it is examined by heavy rainfall, and the effect of engineering treatment process is preliminarily shown. However, the main project is affected by many heavy rainfall after completion, and some subsidiary engineering structures are damaged. In view of the defects in the engineering design, it is analyzed and summarized. In view of the current situation of debris flow, three kinds of supplements are put forward again. Restoration scheme: 1: new branch ditch drainage channel 6#yu7# dam desilting vertical skirt repair anti-scouring wall foundation restoration of water pavement silting and silt pit embankment restoration main ditch dam body repair; Scheme 2: 1 increasing the height of the desilting dam to repair the foundation of the anti-scour wall, the foundation of the water pavement, the siltation and siltation field, the embankment, the main ditch dam body, the restoration; Plan 3: 1 desilting 6 # Dam desilting by using the foundation of the embankment, the foundation of the anti-scouring rib and the anti-scouring wall to repair the main ditch dam body, the above three schemes have different control scope, such as the foundation repair of the water pavement, siltation and siltation field, the surrounding embankment and the main ditch dam body repair. The difference of project and scale will lead to the quantity of prevention and cure project and the difference of investment. Finally, according to the actual effect of field management, the paper analyzes, evaluates and suggests measures.
