Erosion damage decreases rock load area, after defining damage variable, the damage stress in rock can be calculated by the method bring forward by lemaitre conveniently. for surrounding rock of a deep buried tunnel under the condition of drained, its seepage character is not only controlled by the high stress in rock, but also influenced by the development of erosion damage. in the whole course of rock " s deformation and failure, its seepage character decreases with the increment of stress in elastic stage, while " increases with the development of failure
巖樣中全應力?應變三軸滲透試驗過程中的典型表現為隨著應力的增加，巖體內的空隙和裂紋受載閉合，滲透性降低，應力達到一定閾西南交通大學鷹士研究生學位論文第11頁值后，巖體內部裂紋發生擴展和歸並，滲透性增強；同樣，地下水的動、靜壓力作用對裂紋的擴展和歸並也起著促進作用。In order to overcome the disadvantages of traditional solid brick, to protect environment and to economize resources, the author first recommended the experimental study of drying and firing of coalstore - shale fired perforated brick. the result assumed the effect of percentage of water content, raw material fineness, temperature and insulation time on property of coalstore - shale perforated or hollow brick
論文首先針對傳統實心磚存在的問題，從環境保護和資源綜合利用出發，以頁巖、煤矸石為原料制磚，通過頁巖、煤矸石制磚中乾燥、焙燒試驗研究，總結了原料化學成份、顆粒粗細程度、乾燥速度、含水率以及焙燒溫度等因素對煤矸石多孔磚、空心磚性能的影響。Eight concrete samples of different compound ratio of artificial lightweight aggregate ( coarse aggregate of expanded shale ) and ordinary aggregate, water - reducing admixture, expanding admixture, etc, are compounded firstly, based on the research of main properties such as agitating property, strength, dry surface density and deformation, an optimum compound ratio of the concrete with high strength ( cl40 ), light density ( 1800 ) and slight expand is achieved
首先，採用人造輕骨料（頁巖陶粒）及普通骨料，加入減水劑、膨脹劑等，配製出了八種不同配合比的輕骨料砼與普通砼，並對其和易性、強度、干表觀密度、變形等主要性能進行了試驗研究，得到了強度等級cl40 ，密度等級1800的輕骨料中高強度微膨脹砼最佳配合比。
