【摘要】：伴隨著中國經(jīng)濟發(fā)展戰(zhàn)略開始向西部轉(zhuǎn)移以及我國開發(fā)西部的戰(zhàn)略計劃執(zhí)行,黃土地域高速公路建設(shè)飛速發(fā)展,各區(qū)域項目實際實施中又因地理條件不同遇到了許多地質(zhì)地形的施工問題,地質(zhì)方面的問題表現(xiàn)的尤為突出,高速公路是由路基、橋涵、隧道組成的,橋涵、隧道地目前施工中因施工費用多、項目重視程度高,問題較少,而路基因施工粗線條,不是控制性工程,各項目重視程度低,使得項目施工中問題頻發(fā),最近十多年高速公路路基施工中邊坡施工問題暴露的尤其明顯。于是,精確評判公路邊坡的穩(wěn)定性,并有針對性地提出治理防護措施,從而使得項目的滑坡治理合乎安全、適宜工程。文中根據(jù)銅黃高速公路滑坡為研究對象,對研究區(qū)的工程地質(zhì)概況、氣象水文特征、地形地貌、地層巖性及滑坡的基本地質(zhì)條件等進行了具體闡述,結(jié)合這些工程地質(zhì)條件,根據(jù)現(xiàn)場調(diào)查,鉆探試驗,從滑體特征、變形破壞特征、滑動面等方面研究了滑坡的發(fā)生條件和特性。認真分析了具有代表性的四段滑坡的形態(tài)、變形、結(jié)構(gòu)、滑帶土和滑面等方面的特征,提出了四處滑坡的產(chǎn)生原因。通過分析該滑坡的形成原因,了解到影響此處滑坡形成的敏感性因素主要為軟弱結(jié)構(gòu)面和高臨空條件。最后根據(jù)實際工程情況,綜合經(jīng)濟性、實用性、必要性提出治理滑坡的方案,具體工程措施有抗滑樁、抗滑擋墻、窗式骨架護坡和排水措施相結(jié)合共同作用的防護方法,以及滑坡防護措施建造過程中需要留意的相關(guān)事項。本文以銅黃高速公路實際工程為背景,針對滑坡形成原因和滑坡的治理對策進行探討,對今后高速公路處置相似滑坡具有一定的借鑒和參考意義。
[Abstract]:With China's economic development strategy beginning to shift to the west and the implementation of our country's strategic plan to develop the western region, the highway construction in the loess region has developed rapidly. In the actual implementation of various regional projects, due to different geographical conditions, there are many construction problems of geological topography, especially in geological aspects. The expressway is composed of subgrade, bridge, culvert, tunnel, bridge and culvert, and the highway is composed of subgrade, bridge and culvert, and bridge and culvert. At present, due to the high cost of construction, the high degree of attention to the project and the less problems in the tunnel construction, the road gene construction is rough line, not a control project, each project is low attention, which makes the project construction problems occur frequently. In the last ten years or so, the problems of slope construction in highway roadbed construction have been exposed especially. Therefore, the stability of highway slope is judged accurately, and corresponding measures are put forward, so that the landslide treatment of the project is safe. According to the landslide of Tonghuang Expressway, the engineering geology, meteorological and hydrological characteristics, landform and landform, stratigraphic lithology and basic geological conditions of landslide are expounded in this paper. Combined with these engineering geological conditions, according to field investigation and drilling test, the occurrence conditions and characteristics of landslide are studied from the aspects of sliding body characteristics, deformation and failure characteristics, sliding surface, etc. Based on the characteristics of deformation, structure, sliding zone soil and sliding surface, the causes of landslide are put forward. It is understood that the main sensitive factors affecting the formation of landslide here are weak structural plane and high imminent condition. Finally, according to the actual engineering conditions, comprehensive economy, practicability and necessity, the project of landslide control is put forward. The concrete engineering measures include anti-slide pile. The protection methods of anti-slide retaining wall, window frame slope protection and drainage measures, as well as the relevant matters needing attention in the construction of landslide protection measures, are discussed in this paper, which is based on the actual project of Cu-Huang Expressway. This paper probes into the causes of landslide formation and the countermeasures of landslide treatment, which has certain reference and reference significance for the future disposal of similar landslide on expressway.
