【摘要】：邊坡的防護與治理是巖土工程中比較常見的技術(shù)問題，涉及到國防、公路、鐵路、水利、工民建和市政等各個領(lǐng)域。以往對邊坡的研究主要是針對順層邊坡，，而對反傾邊坡的巖移機理和滑坡模式研究較少。反傾邊坡是指具有反傾結(jié)構(gòu)面（即邊坡的傾向與結(jié)構(gòu)面的傾向相反）的邊坡。反傾結(jié)構(gòu)面的存在及其特征對于邊坡的變形和破壞方式具有決定性的控制作用。因此研究反傾邊坡具有非常重要的理論和實際意義。 論文以某公路邊坡為分析課題，系統(tǒng)的研究了反傾巖質(zhì)邊坡的變形破壞規(guī)律，提出了一個較為合理的反傾巖質(zhì)邊坡穩(wěn)定性分析方法及支護技術(shù)。主要研究內(nèi)容及結(jié)論有： （1）系統(tǒng)研究影響反傾巖質(zhì)邊坡穩(wěn)定性的主要因素，采用邁達(dá)斯GTS分析了這些因素對反傾巖質(zhì)邊坡穩(wěn)定性的影響程度； （2）根據(jù)反傾巖質(zhì)邊坡穩(wěn)定性的影響因素分析反傾巖質(zhì)邊坡的破壞類型，認(rèn)為反傾巖質(zhì)邊坡的破壞主要是傾覆破壞和剪切滑移破壞； （3）建立不同破壞模式下反傾巖質(zhì)邊坡破壞的力學(xué)模型，采用經(jīng)典力學(xué)理論對反傾巖質(zhì)邊坡的破壞機理進行分析，認(rèn)為反傾巖質(zhì)邊坡的破壞機理主要是“懸臂疊合梁”的傾倒，反傾巖質(zhì)邊坡具有結(jié)構(gòu)承載調(diào)整—結(jié)構(gòu)強度弱化—結(jié)構(gòu)失穩(wěn)的變形破壞規(guī)律。 （4）根據(jù)反傾巖質(zhì)邊坡的力學(xué)分析結(jié)果，開展反傾巖質(zhì)邊坡的支護技術(shù)研究，提出采用預(yù)應(yīng)力錨索（桿）框架來對反傾巖質(zhì)邊坡進行加固的處理措施； （5）以某公路邊坡為工程實例，介紹反傾巖質(zhì)邊坡的監(jiān)測技術(shù)，并對該反傾巖質(zhì)邊坡進行加固處理和穩(wěn)定性評價。
[Abstract]:Slope protection and treatment is a common technical problem in geotechnical engineering, involving national defense, highway, railway, water conservancy, civil construction and municipal. However, there are few studies on the mechanism of rock movement and landslide model of reverse slope, which refers to the slope with reverse inclined structural plane (that is, the inclination of slope is opposite to that of structural plane). The existence and characteristics of the reverse inclined structural surface play a decisive role in controlling the deformation and failure mode of the slope, so it is of great theoretical and practical significance to study the reverse slope. In this paper, a highway slope is taken as the analysis subject, and the law of deformation and failure of anti-dip rock slope is studied systematically. In this paper, a reasonable method of stability analysis and supporting technology of anti-dip rock slope is put forward. The main research contents and conclusions are as follows: 1) the main factors affecting the stability of anti-dip rock slope are systematically studied, and the influence degree of these factors on the stability of anti-dip rock slope is analyzed by Midas GTS. (2) based on the analysis of the factors affecting the stability of the backdip rock slope, the failure types of the backdip rock slope are analyzed, and it is considered that the failure of the reverse dip rock slope is mainly caused by overturning failure and shear-slip failure; 3) to establish the mechanics model of reverse dip rock slope failure under different failure modes, and to analyze the failure mechanism of reverse dip rock slope by classical mechanics theory. It is considered that the failure mechanism of backdip rock slope is mainly the toppling of cantilever composite beam, and the reverse dip rock slope has the deformation and failure law of structural load-bearing adjustment, structural strength weakening and structural instability. (4) according to the results of mechanical analysis, the supporting technology of anti-dipping rock slope is studied, and the treatment measures of reinforcement of anti-dipping rock slope with prestressed anchor cable (rod) frame are put forward. Taking a highway slope as an engineering example, this paper introduces the monitoring technology of the anti-dip rock slope, and carries on the reinforcement treatment and the stability evaluation to the anti-dip rock slope.
