【摘要】：近期,大夫山森林公園西側(cè)山體上發(fā)生滑坡,滑坡分南東和北西兩個(gè)變形體,北西變形體上部有一高壓電塔,滑坡下部為禺山西路和東新高速,目前滑坡仍有繼續(xù)擴(kuò)展趨勢(shì),給山體上部電塔及下方道路與行人造成了極大的安全隱患。因此對(duì)大夫山森林公園滑坡進(jìn)行危險(xiǎn)性評(píng)價(jià)和穩(wěn)定性分析是極為必要的。本文闡述了滑坡危險(xiǎn)性評(píng)價(jià)的研究意義、國(guó)內(nèi)外滑坡危險(xiǎn)性分析和穩(wěn)定性評(píng)價(jià)的研究現(xiàn)狀,并確定出大夫山森林公園滑坡的危險(xiǎn)性分析和穩(wěn)定性評(píng)價(jià)的研究方法。在查閱大量關(guān)于研究區(qū)的區(qū)域地質(zhì)資料和滑坡的發(fā)育歷史后,對(duì)研究區(qū)內(nèi)2個(gè)滑坡點(diǎn)進(jìn)行了野外實(shí)地調(diào)查,對(duì)各點(diǎn)的危險(xiǎn)性進(jìn)行較為準(zhǔn)確的野外評(píng)價(jià),提取用于進(jìn)行滑坡危險(xiǎn)性評(píng)價(jià)和穩(wěn)定性分析的各因素的參數(shù)。采用模糊綜合評(píng)判法對(duì)滑坡的危險(xiǎn)性進(jìn)行了分析。此外,本文還通過(guò)GEO-STUDIO詳細(xì)分析了該滑坡的穩(wěn)定性,分析過(guò)程以北西變形體為例,利用Seep/W模塊分析出該邊坡的天然狀態(tài)孔隙水壓力等,并使用其與Sigma/W模塊進(jìn)行耦合,計(jì)算出邊坡位移狀態(tài),進(jìn)而推出邊坡剪出位置,最后利用Slope/W模塊,得出滑坡的穩(wěn)定性系數(shù),判斷出滑坡變形趨勢(shì)。通過(guò)模糊綜合評(píng)判法所得到滑坡危險(xiǎn)性的分析結(jié)果以及基于GEO-STDUIO的穩(wěn)定性分析結(jié)果,基本上與野外現(xiàn)場(chǎng)的勘察結(jié)果是一致的,所以使用該方法對(duì)大夫山森林公園危險(xiǎn)性評(píng)價(jià)及穩(wěn)定性評(píng)價(jià)是合理可信的。
[Abstract]:Recently, there was a landslide on the west side of the forest park in Dushan. The landslide was divided into two metamorphosed bodies, one in the south and the other in the north. There is a high voltage tower in the upper part of the deformed body in the north and west. The lower part of the landslide is Yu Shanxi Road and Dongxin Expressway. At present, the landslide still has a tendency to continue to expand. To the upper mountain tower and the lower road and pedestrian caused a great safety hazard. Therefore, it is necessary to evaluate and analyze the stability of the landslide in Dushan Forest Park. In this paper, the significance of landslide risk assessment, the research status of landslide risk analysis and stability assessment at home and abroad, and the research methods of landslide risk analysis and stability evaluation in Dushan Forest Park are described. After consulting a large amount of regional geological data and the development history of landslides in the study area, a field investigation was carried out on two landslide sites in the study area, and a more accurate field evaluation of the danger of each point was carried out. The parameters of various factors used for landslide risk assessment and stability analysis were extracted. The risk of landslide is analyzed by fuzzy comprehensive evaluation method. In addition, the stability of the landslide is analyzed in detail by GEO-STUDIO. The process of analyzing the deformation body north to the west is taken as an example. The natural pore water pressure of the slope is analyzed by Seep-W module and coupled with Sigma / W module. The displacement state of the slope is calculated, and then the slope shear position is deduced. Finally, the stability coefficient of the landslide is obtained by using Slope / W module, and the deformation trend of the landslide is judged. The results obtained by fuzzy comprehensive evaluation and stability analysis based on GEO-STDUIO are basically consistent with the field survey results. So it is reasonable and reliable to use this method to evaluate the risk and stability of Dushan Forest Park.
