Using vogel ' s wear index as the rail side wear index, the paper analyzes the side wear variations of rail head when the parameters in the wheel / rail system vary, analyzes the influences of track irregularity on rail uneven wear on gauge corner emphatically. this paper analyzes the rail side wear dates measured by track division of shan hai guan since 1990, then gains the relationship between side wear and traffic volume and sums up the characteristics and regularities in the formation and development of side wear. in the end, some measures for regarding the side wear on curves are put forward
從輪軌摩擦、輪軌接觸幾何關系、輪軌接觸應力和輪軌蠕滑等方面對鋼軌側面磨耗機理進行了探討，從軌道幾何參數、機車車輛運營條件等方面對鋼軌側面磨耗的影響因素進行了重點分析和總結；應用輪軌系統動力學，建立了輪軌空間耦合振動時變模型，採用vogel側磨指數作為鋼軌側磨指標，系統分析了輪軌參數變化的情況下，軌頭側面磨耗的變化規律，重點分析了軌道不平順對鋼軌不均勻側磨的影響；對山海關工務段1990年以後現場測得的曲線鋼軌側磨數據進行了分析，通過擬合得到了鋼軌側磨量與運量的關系曲線，並總結了曲線上股鋼軌側面磨耗的特徵和發生、發展規律；最後提出了一些減緩曲線鋼軌側面磨耗的措施。At first it analyzes the bedding rock slope ' s bedded rock and its incontinuity face, and studies the stress, strain, stability ' s condition of the bedding rock slope, fully considering the cohesive force of rock layer and incontinuity face. geologic mechanics models of two types of bedding rock slope are set up, the instability coefficient of bedding rock slope under different mechanical parameters is computed, and the conclusion that the stability of bedding rock slope is relation to rock layerer, cohesive force of incontinuity face, inner friction angle and rock layer obliquity has been gotten. based on the above discussion, the thesis comes down the influence of rock layer and the incontinuity face on the bedding rock slope to incontinuity face ' s influence factors, and discusses other factors that influence the bedding rock slope ' s stability, so gains the evaluating and forecasting index marks
本文首先對順層邊坡的層狀巖體及其中的層理面和不連續面進行了分析，對其應力應變進行了研究，得出了順層邊坡的穩定性不僅與巖體中巖石的強度有關，還與巖體中層理面及不連續面的內聚力、內摩擦角及其傾角有關；論文建立了層理面和節理面的地質力學模型，討論了其力學參數變化對邊坡穩定性的影響，並在此基礎上將層理面和節理面歸納為順層邊坡穩定性的結構面影響因素，同時討論了影響順層邊坡穩定性的其他因素，從而得出順層邊坡穩定性的評價預測指標。
