This paper makes the fitting analysis of the field test data according to the hyperbolic model established by the interface spring theory,and simulates the experiment of bolt upraising by means of the finite element method.After the comparison of the calculated results with the field test results,the paper draws the main conclusion that good fitting effect can be obtained when the hyperbolic model is adopted in fitting the relationship between axial force and depth.The interfacial shearing stiffness will so...

文章按照界面弹簧理论所建立的双曲线模型，对试验实测数据进行了拟合分析，并采用有限元法对锚杆上拔试验进行了模拟，对比计算结果和实测结果得出的主要结论为：采用双曲线模型拟合锚固轴力随深度变化的曲线，可以取得良好的拟合效果；在逐级加载的条件下，界面的剪切刚度呈软化的趋势；在锚固界面没有发生较大滑移的情况下，计算位移和实测位移比较接近。

Based on the results of exploration and in-site test of typical waste dump in southwest mountainous area,the analysis theory and method of waste dump rainfall infiltration are discussed beginning at analysing coal waste's mechanics characteristic and seepage theoty. Fllowed estimating method of waste dump stability is discussed influenced by rainfall. At last a typical engineering example of coal waste dump landslide influenced by rainfall is researched, acquiring research fruit hereinafter.①Particular exploration of typical waste dump in chongqing area and analysis estimate to its area engineering geology are done. Granule gradation、water content、nature density、dry densit etc parameter of waste granular media are tested. The mechanics characteristic of waste are researched by in-site shear experimentation、compressibility experimentation and infiltration experimentation.②The coal waste dumping is different from other consecutive solid material as incompact granule structure. Its shear strength and transforming characteristic also have itself characteristic.

ZSM two-drum pulse low net work of the screen, pulp pressure from the top of the screen to cut into the screen, the two fall in the middle drum sieve, sieve in the drum inside and outside of the pressure difference and the dual-rotor rotary-wing together, qualified fiber Through the inside and outside the drum screen after screen to the body at the bottom of the pool, and then by the good plasma discharge tube machine, the screen remained in the dark between the flow of rough slurry residue by the rotor and driven together to drum sieve under the tailings from the slot after the Slag discharge pipe.

ZSM双鼓式低脉冲网前筛工作时，纸浆从压力筛的上部切向进入筛体，流到两个筛鼓中间，在筛鼓内外的压力差及双旋翼转子的共同作用下，合格纤维通过内、外筛鼓后汇集到筛体底部，然后经良浆管排出机外，留在筛鼓之间的粗渣受到浆流和旋翼的推动，汇聚到筛鼓下的尾渣槽后从排渣管排出。

From the microstruture observation, this dilatancy produced is clearly associated with a change from crystal plasticity plus minor cataclasis (formation of closed intragranular cracks) at high pressure (20MPa) to crystal plasticity plus significant cataclasis (involving axial cracking, intragranular cracking, crack opening and shearing) below 10MPa.

此时的微结构研究也发现：岩盐流变过程中膨胀的产生是由高围压下（20MPa左右）的晶体塑性加较少碎裂到低围压下（10MPa左右）的晶体塑性加主要的碎裂（包括纵向裂隙、晶内裂隙以及裂隙的张开与剪切）。

By contrast Real Madrid our next CL opponents (who have as much money as Chelsea, and to can sign nearly any player they like); spent last night looking chumps for 80 minutes against Osasuna, they were disjointed, showed no cohesion and were stoppped playing by a defensive well organised Osasuna who should have won the game.

对比我们下个冠军联赛的对手皇马（和切尔西一样有钱，几乎能签下所有他们想要的球员）；昨晚对阵奥萨苏纳时80分钟形同梦游，他们一点都不团结，面对防守出色的对手显得毫无办法，他们理应输掉比赛。

The material enter into the drier through the screw charger, under the powerful effect of stirring at high-speed rotation, the materials are distributed under the function of strike, friction and cut the block state materials will soon be smashed and contact the hot air fully, the materials are heated and dried.

物料由螺旋加料器进入干燥器内，在高速旋转搅拌器的强烈作用下，物料受到撞击，摩擦及剪切的作用下得到分散，块状物料迅速粉碎，与热空气充分接触、受热、干燥。

The results indicate that when soil and pile are same, the shear stresses between pile and soil under the ultimate situations of different modes are different; the negative friction on pile induced by surcharge is maximum; and the negative friction of uplift pile is minimum; the friction of pile top induced by pressing pile and bottom-loaded pile is between them.

结果表明，同种土体和桩体条件下，各种模式达到极限状态时桩－土间剪切应力不同，堆载作用下负摩擦力值最大，抗拔桩负摩阻力值最小，桩顶受压桩、托桩的摩阻力值介于其间；桩材泊松比在0.15~0.35范围内时，桩侧摩阻力随泊松比的增大而增大。

Although paper has to be fed and held down manually, arbitrary hold-down pressure against paper is thus available to avoid the disadvantage resulting from improper hold-down pressure The paper-cutting blade holder is driven by a motor, but it can also be operated by means of a handle to suit the needs of the location where power supply is not yet available.

本机的送纸与压纸需要手动，但压纸时，压力可任意选择，故可避免压纸的压力不适所引起的弊病。刀座切纸是由电动机驱动，但也可用手柄摇动，可适用在无电源的状态下下使用。

Sample 1 had no phenomenon of pulling-out and debonding of fibres under vertical compression load and the interface bonding intensity is strong between the fibres and the matrix. The material shows brittle fracture: if σ(subscript ⊥)=60.7MPa. However, sample 1 has the phenomenon of fibres debonding because of the shearing stress between the fibres and the matrix under parallel compression load. The material shows tough fracture:σ(subscript ∥)=52.6 MPa.
