因為正值寒冬,又逢大陸冷氣團過境,濃霧細雨冷風時隱時現,平時習慣溫熱氣候的人,一時之間無法適應這種突如其來的寒冷,可是大家由愛心為出發點,反而更努力打坐割草挖土種樹以增強體溫適應爬上高山快達到山頂時,大家與山坡幾乎成90度的垂直面,必須以雙手用力攀登互相拉上去,路又滑跌倒難免,爬下山來時,人人幾乎都是滾下來的,許多不習慣爬山的人,雙腿筋骨酸痛得寸步難行,然而內心依然滿足。A bearing surface transmits the interaction between an arch dam and its foundation, the strength of which directly affects the constraint of the bedrock to the dam, and thus affects the stress and deformation of the dam. the influence is studied in this paper with nonlinear finite element method, as an example, for a high arch dam in design. the results show that the influence on stress is only limited within the local area near the bearing surface, larger on the maximum principal tensile stress than on the principal compression stress, and the decrease of the strength does not cause unlimited increase of the maximum stress. the influence on the displacement of the top of the dam is smaller than that of the bottom of the dam, especially the relative downstream displacement. at the lower strength of the bearing surface, the relative downstream displacement at the bottom of the dam increases with the decrease of the strength
建基面是傳遞拱壩和基巖相互作用的紐帶,它的強度直接影響基巖對壩體的約束,從而影響壩體的應力和變形.採用非線性有限單元法,以設計中的某高拱壩為例,分析建基面強度對壩體應力和變形的影響.結果表明建基面強度對壩體應力的影響僅限於建基面附近的局部范圍,對最大主拉應力的影響要大於對最大主壓應力的影響,建基面強度的降低不會無限地增大壩體的應力數值;建基面強度對壩頂位移的影響較小,但對壩底位移(尤其是順河向相對位移)的影響較大,當建基面強度較低時,壩底順河向相對位移隨建基面強度的降低而增大Disc specimens have great application in testing the mechanic properties of rock, such as the cracked chevron notched brazilian disk ( ccnbd ) and the cracked straight - through brazilian disc ( cstbd ) used in testing rock fracture toughness, the brazilian disc and the flatted brazilian disc ( fbd ) used in testing rock tensile strength

十幾年的高等級公路建設實踐表明,水泥路面的使用壽命遠遠小於其設計壽命,往往在通車幾年後就出現一些病害,如坑槽、斷板等病害,帶來的直接、間接經濟損失和不良的社會影響。解決這些問題,除了運用行政強制手段控制超載車輛外,必須提高水泥混凝土的彎拉強度、疲勞強度、耐磨強度、阻裂限縮能力,從而提高水泥混凝土路面的使用壽命。With the input of a vibration acceleration history of subway train, a full dynamic analysis of soil - pile - structure is carried out. the propagation of vibration wave on the ground and vibration responses of the huge platform and the storied buildings are analyzed. some conclusions are drawn as follows : ( 1 ) with the increase of the distance to the vibration source, vibration intensity of the ground decreases ; ( 2 ) the vibration intensity of the ground in vertical direction is slightly larger than that in horizontal direction ; ( 3 ) with the increase of the distance to the vibration source, the situation that the vibration intensity of each building in horizontal direction is maximum at highest and lowest story whereas minimum at the middle story changes gradually to that decreasing with the height of building ; ( 4 ) in vertical direction, the vibration velocities and accelerations at the end points of each story of a building are the nominal identical, which indicates that the vertical vibration of them is unanimous ; ( 5 ) the vibration intensity in vertical direction of a building is larger than that in horizontal direction ; ( 6 ) increasing of the elasticity of track is an effective way to abate vibration of ground and buildings
