【摘要】：京昆高速四川境內(nèi)段沿線地形地貌多樣,地質(zhì)條件復(fù)雜,川北低山區(qū)、川中盆地區(qū)和川西南中山區(qū)邊坡特征差異性較大,邊坡處治數(shù)量多、規(guī)模大,公路邊坡的處治呈現(xiàn)出多樣性、復(fù)雜性的特征。邊坡工程中合理的處治方案的制定,不僅與處治技術(shù)水平有關(guān),更與當?shù)毓こ探?jīng)驗息息相關(guān)。公路邊坡所處區(qū)域地形地貌、地質(zhì)狀況、水文條件、地震作用等多種因素相互聯(lián)系與制約,影響著邊坡的穩(wěn)定程度。在邊坡穩(wěn)定性分析基礎(chǔ)上,如何合理評價公路邊坡處治方案的適宜性,成為工程研究學(xué)界長時間以來以期解決的重要難題。本論文收集整理了京昆高速四川境段公路特殊路基邊坡資料,在分析邊坡穩(wěn)定性特征因素的基礎(chǔ)上,總結(jié)沿線區(qū)域典型邊坡處治方案,對京昆高速四川境段特殊路基邊坡處治技術(shù)的適宜性進行分析。主要進行以下研究以：(1)以京昆高速四川境段特殊路基邊坡的外形條件、邊坡結(jié)構(gòu)類型條件和邊坡的環(huán)境條件為特征因素指標,通過統(tǒng)計分析,量化各分區(qū)處治邊坡與影響邊坡穩(wěn)定性的特征因素之間的關(guān)系,進而以各項特征因素為參變量,研究其與擋墻、抗滑樁、錨桿、錨索及其組合等典型處治措施與特殊路基之間的相關(guān)關(guān)系。(2)基于現(xiàn)場監(jiān)測和數(shù)值分析方法,對西(昌)攀(枝花)高速公路K132邊坡進行現(xiàn)場監(jiān)測分析和數(shù)值計算。監(jiān)測結(jié)果表明降雨及施工擾動因素對邊坡穩(wěn)定性影響較大；錨桿與框架錨桿方案的比選結(jié)果表明兩者都可一定程度改善坡體淺層應(yīng)力位移場,但是框架錨桿更有利于控制淺層坡體變形；框架錨索模擬結(jié)果表明,錨索框架梁有效地提高了邊坡的穩(wěn)定性。(3)依托深切低山峽谷區(qū)、淺切平原丘陵區(qū)和深切低山丘陵區(qū)特殊路基邊坡典型處治工程,應(yīng)用EMU巖質(zhì)邊坡軟件進行穩(wěn)定性驗算,從定性和定量角度對典型邊坡處治進行措施的適宜性進行評價分析。
[Abstract]:There are various landforms and complicated geological conditions along the Beijing-Kunming Expressway in Sichuan Province. The slope characteristics of the low mountainous area of northern Sichuan, the middle basin area of Sichuan Basin and the middle mountain area of southwest Sichuan are quite different, and the number and scale of slope treatment are large. The treatment of highway slope presents the characteristics of diversity and complexity. The formulation of reasonable treatment scheme in slope engineering is not only related to the technical level of treatment, but also closely related to local engineering experience. The regional landform, geological condition, hydrological condition, seismic action and other factors of highway slope are related and restricted, which affect the stability of slope. On the basis of slope stability analysis, how to reasonably evaluate the suitability of highway slope treatment scheme has been an important problem in engineering research circles for a long time. Based on the analysis of the characteristic factors of slope stability, this paper collected and sorted out the special subgrade slope data of the Beijing-Kunming Expressway in Sichuan Province, and summarized the typical slope treatment plan of the region along the line. The suitability of slope treatment technology for special subgrade in Jing-Kun high-speed Sichuan border section is analyzed. The following studies were carried out: (1) taking the shape condition of the special subgrade slope, the structural type condition of the slope and the environmental condition of the slope as the characteristic factor indexes of the special roadbed slope of the Beijing-Kunming Expressway in Sichuan Province, through statistical analysis, Quantifying the relationship between the treatment of slope and the characteristic factors affecting the stability of slope, and then taking each characteristic factor as parameter, studying its relation with retaining wall, anti-slide pile, anchor rod, etc. Based on the field monitoring and numerical analysis method, the field monitoring analysis and numerical calculation of K132 slope of Xichang climbing (Zhihua) Expressway are carried out. The monitoring results show that rainfall and construction disturbance factors have great influence on slope stability, and the comparison of anchor rod and frame anchor scheme shows that both of them can improve the shallow stress and displacement field of slope body to some extent. But the frame anchor rod is more favorable to control the deformation of shallow slope body, and the simulation results of frame anchor cable show that the stability of slope is improved effectively by the frame anchor cable beam. In the typical treatment project of special subgrade slope in shallow-cut plain hilly area and deep low hill region, the stability of typical roadbed slope is checked by EMU rock slope software, and the suitability of treatment measures for typical slope is evaluated and analyzed from the angle of qualitative and quantitative analysis.
