In this paper, the spatial distribution of soil erosion intensity on a long and straight cultivated slope was studied using 137Cs measurement and wavelet analysis. The results showed that there existed an fluctuant period of soil erosion intensity with 142m along 4 transects downslope, which suggested that the intensity of soil transporting changes between weak and strong alternately downslope during the impact of long-term erosive rainfall.
本研究通过采集开垦近100年的黑土直型坡耕地的土壤样品,利用137Cs示踪技术,结合小波分析方法,研究了长坡长直型坡耕地50多年来土壤侵蚀强度的空间变化规律,结果显示4个断面顺坡方向上的坡面侵蚀强度均存在着坡长为142 m的强弱交替变化的波动周期,这反映了长坡长直型坡土壤在长期的降雨侵蚀过程中,泥沙沿坡面输移的强弱交替变化。

Similarly, the AMR begin to increase and then decrease with increasing the thickness d of the seed layer, and has a maximum value at a critical thickness d of 5.32nm. Compared to the permalloy films deposited on Ta seed layer ,the AMR enhancement of 10%-46% is observed in the permallay films deposited on (Ni0.82Fe0.18)1-xNbx seed layer.(2) The coercivity Hc1 obtained for magnetic field H applied paralley to the easyaxis is large than Hc2 for H applied perpendicular to the in-plane easy axis, and both of coercivity are consistent with the change of x.
2沿样品易轴方向的矫顽力Hc_1比难轴方向的矫顽力Hc_2大,两者随Nb原子的百分含量x的变化是一致的,饱和磁化强度Ms随x的增大先增大后减小,在x=27.1%处,Hc_1和Hc_2都比较小,而Ms则达到最大;种子层厚度d不能明显改变坡莫合金薄膜的磁性能;与以传统材料Ta为种子层的坡莫合金薄膜相比,以Ni_(0.82Fe_(0.18)_(0.829)Nb_(0.271)为种子层的坡莫合金薄膜的矫顽力只有轻微减小,但是Msg 以w讪Fq.t)lkNk为种于层的坡莫合全薄膜的各向异性戳电阻及磁性能研究却要大,mk坡莫合金层厂度!

Slope stabilization treatment of this region including polyathylen strip method and thin layer hydrograsser method, some small slopes even have not been treated. A few of the treated slopes fail during heavy rainfall. The post method of treatmenting these slopes obviously doesn't function properly. The purposes of this research is to suggest suitable methods for gravel slopes, and consider slope behavior and stability.

Through the research of direct search method based on 3D FEM, and its application for the tunnel slope stability analysis, the objectives of this work in this paper are as follows:1. The dynamic programming as well as its application for 3D side slope stability analysis is studied. With the introduction of graph theory concept, one kind of glide pattern of 3D slope is constructed, and the critical slip surface with smallest safety factor is searched with the aid of one auxiliary function including safety factor;2. Using the C++ programming language, the 3D slope stability analysis and the direct search procedure is established, and this method is testified applicably by some contrast analysis, also some influence factor in analysis is discussed;3. Integrated with the different actual situation in tunnel slope, considered its excavation, timbering and rain infiltration, its stability influence and rule is researched used this method, also some processing measure is proposed.

The field experiments on the secondary flow developed on the lee side show that there are strong sand transport potential at the lee side of the dunes near the surface because of the decreasing of the sand grain size and the other factors. The transport directions are nearly vertical to the dune trends. Those factors and the sand slumping on slip face, and the sand transport processes on the stoss slope make the transverse dunes maintaining their morphology under the advance processes.
对沙丘背风坡发育的二次流的野外观测表明,近地面一定高度内沙丘背风坡气流仍有一定的强度,由于背风坡的沙丘沙粒径较小等因素,背风坡气流仍保持一定强度的输沙率,输沙方向与沙丘走向基本上垂直,这种作用与沙物质向背风坡崩落、迎风坡的输沙过程等共同作用,因而使横向沙丘在运动中保持其形态。

After analysizing the results of SSRFEM and centrifugal model test, someconclusions are drawn that, the depth of slip surface implies that the Bishopssimplied method cannot indicate the true failure mechanism for the slopes reinforcedwith piles. The rate of safety factors decreases with the pile spacing decreasing, andthe salty factor of the slopes is the largest when the reinforced piles are installed in themiddle of the slopes, regardless of pile head confining conditions, and the deflection,maximum bending moment and shear force in the reinforced piles in the criticalcollapse are the biggest meantime. The fixed and hinged head condition of the pilesresults in smaller bending moment in the piles than that in unrotated and free headcondition, therefore the restrained pile head condition is recommended in the design.
3不同特性与工况下抗滑桩与土体相互作用的数值分析与离心模型试验研究表明:采用简化Bishop法计算得到的滑动面不能反映抗滑桩加固边坡的破坏机理,抗滑桩设置在边坡中部和减小桩间距有利于提高边坡稳定安全系数,而此时抗滑桩在边坡临界破坏时的挠度、最大弯矩和最大剪力相对较大;桩头固定、铰接与桩头自由、平移相比,所加固边坡的整体水平位移及边坡临界破坏时抗滑桩的最大弯矩相对较小,而稳定安全系数则较大,因此在进行抗滑桩设计时应尽量选择桩头固定与铰接的型式,或对桩头进行锚固以改善抗滑桩的受力特性,提高边坡的稳定安全性状。

Home position shear tests of slope rock, point loading tests and indoor AMD simulation action tests in XingQiao concave slope had show shearing strength and coherence between body layers of quartz sandstone decrease by 13.2%~21.3% after attacked by AMD, the angle of internal friction between layers is decreased by 5.0%~7.5%, in general, AMD affects the rocks mechanical property at range of 60~100m interior the perpendicular slop. Data analysis shows: 1 The actions to slope are major focused on zone of weakness, shearing strength of slope foot and AMD centre are reduced by 52% and 64.7% separately. 2 The explosion stress wave of long distance field has obviously increasing influence to disturbance amplitude value of slope with increasing of the slope height and distance, the response of the top of slope and fault region are obvious as well as damage effect; the foot of slope is with smallest disturbance amplitude value, the disturbance amplitude value of the step close to free face is obviously bigger than the interior of slope. 3 With the coupling effect of the AMD and explosion loading, the stress distribution inside of slope mainly presents characters of explosion stress field; the area affected by AMD becomes a weak area of shearing stress.

The cherishing and training of some trees; the cautious pruning of others; the nice distribution of flowers and plants of tender and graceful foliage; the introduction of a green slope of velvet turf; the partial opening to a peep of blue distance or silver gleam of water: all these are managed with a delicate tact, a pervading yet quiet assiduity, like the magic touchings with which a painter finishes up a favorite picture.
