technical engineering of our country is developing rapidly. The related departments such as traffic, water conservancy, mine and so on will involve a lot of slope problems, especially the slope of mountainous area. Because of the influence of various geological environment, the stability of slope in mountainous area directly influences With the safety of the people in the mountainous area and the landslide disaster seriously endangering the national infrastructure, it is necessary to study the stability of geotechnical slope. Based on the analysis and discussion of the stability of the slope, the failure forms and influencing factors of the slope are introduced, and the stability analysis method of the slope is summarized. The concrete application of the slope stability analysis method is illustrated by an example, Finally, the design method of slope stability is discussed.Key words: slope。 淺析巖土邊坡安全問題及處理措施 摘 要 :我國的巖土工程發(fā)展迅速,交通、水利、礦山等相關(guān)部門都會涉及很多邊坡問題,特別是山區(qū)的邊坡,由于各種地質(zhì)環(huán)境的影響,處于山區(qū)地段的邊坡穩(wěn)定性直接影響著山區(qū)老百姓的人身安全,滑坡災(zāi)害嚴重危及到國家基礎(chǔ)建設(shè),所以對巖土工程邊坡的穩(wěn)定性研究十分必要。在對邊坡進行穩(wěn)定性分析和討論的基礎(chǔ)上,介紹了邊坡的破壞形式和影響因素,概述了邊坡的穩(wěn)定性分析方法,并通過實例闡述了邊坡穩(wěn)定性分析方法的具體應(yīng)用,最后對邊坡穩(wěn)定性的設(shè)計方法進行了探討。 rock and soil。 analysis。但如對之認識清晰、高度重視,由高邊坡、高填土引發(fā)的巖土工程問題,將得到有效解決,可以杜絕安全隱患,可以節(jié)約工程開支。1 邊坡穩(wěn)定性影響因素原因分析 深入理解破壞機理才能準確有效的理解工程中常用的邊坡處理方法。巖質(zhì)邊坡破壞類型可分為:滑移—壓致拉裂,即在平緩層體坡中河谷下切或邊坡開挖引起的坡體沿平緩結(jié)構(gòu)面向坡前臨空方向產(chǎn)生的蠕變滑移?;啤獜澢?,由于前緣滑移面未臨空,使下滑受阻,以致坡腳附近順層梁承受壓應(yīng)力,使之彎曲變形。而巖土體變形特點可以歸為張裂變形、滑移變形、蠕動變形等。高度飽和土坡有事會出現(xiàn)石流破壞。為適應(yīng)這種應(yīng)力狀態(tài)的變化,邊坡出現(xiàn)了不同形式和不同規(guī)模的變形與破壞,這是推動邊坡
