Due to an abundant rainfall and frequent rainstorm, and geographical characteristics of mountain and hills, the potential erosive dynamics of soil erosion is strong. The low resistant erosion ability of ground substance, especially in granite weathering crust and purple rock and its soil are the inner causes of severe soil erosion. The utilization of natural resource of mankind was increased due to characteristics of social and economic environment of the province. The unreasonable land utilization caused vegetation destroy, which is the key factor of soil erosion.
丰沛的降雨和频繁的暴雨,以及多山地丘陵的地形特征,为土壤侵蚀提供了强大的侵蚀潜在动力;抗侵蚀性较弱的地面组成物质,特别是花岗岩和紫色岩风化壳及其土壤,是造成土壤侵蚀特别严重的内在原因;而社会经济环境特点使人类利用自然资源强度增加,出现了一系列土地利用不合理现象,导致其中植被破坏,是造成土壤侵蚀的决定性因子。

By means of FEM simulation and application of the equivalent continuum model and the discrete fissure model, we can conclude that the larger density of fissure, the more identical the two methods will be. Based on this conclusion and characteristic of fissured rocks, a new model called the entity mixed model is suggested. Many examples given in the thesis demonstrate the reliability, effectivity and efficiency of this model.
通过对等效连续介质模型和离散裂隙介质模型的有限元模拟和计算,证实了裂隙密度愈大,两种模型的结果就愈为接近,以这一结论和裂隙发育的特征为基础,本文提出了裂隙岩体渗流分析的统一域混合模型,多个算例表明这一模型是合理、有效的,且具有更普遍的实用价值。

After the result of cohesion-friction model is compared with Coulomb Criterion, it is found that when the results of shearing strength are many and adjacent the strength parameters can not be regressed by least square method, instead the results should be divided into some beelines at that time according to the cohesion-friction model.(4) Discuss the characters of hard structural plane and weak structural plane: The adhesive friction theory is applied to research the changing course of shear area of hard structural plane and its influence on shear stress.
3介绍了岩石强度理论中的粘接摩擦模型,运用此模型分析依附型滑动面的演化过程,并将其推广到边坡岩土体抗剪强度的选取,讨论了不同法向应力下峰值强度和残余强度随法向应力的变化规律,在此基础上给出抗剪强度的选取模式,讨论了对实际取值结果的影响,并与传统的Coulomb准则进行了比较分析,指出直剪试验的法向应力在小应力区的点较多且抗剪强度结果差异不大时,不宜直接运用最小二乘法回归抗剪强度参数,此时应结合粘接摩擦模型对结果进行线性分段。

Introduce the cohesion-friction model of rock strength theory, and extend the model to select the strength of sliding plane, discuss the variation rules of peak strength and residual strength under different normal stress, and then present the selection model of shearing strength. After the result of cohesion-friction model is compared with Coulomb Criterion, it is found that when the results of shearing strength are many and adjacent the strength parameters can not be regressed by least square method, instead the results should be divided into some beelines at that time according to the cohesion-friction model.(4) Discuss the characters of hard structural plane and weak structural plane: The adhesive friction theory is applied to research the changing course of shear area of hard structural plane and its influence on shear stress.

December 10th, I began now to think my Cave or Vault finished, when on a Sudden,(it seems I had made it too large) a great Quantity of Earth fell down from the Top and one Side, so much, that in short it frighted me, and not without Reason too; for if I had been under it I had never wanted a Grave-Digger: Upon this Disaster I had a great deal of Work to do over again; for I had the loose Earth to carry out; and which was of more Importance, I had the Seiling to prop up, so that I might be sure no more would come down.
十二月十日我本以为挖洞的工程已大功告成,可突然发生了塌方。也许我把洞挖得太大了,大量的泥土从顶上和一旁的岩壁上塌下来,落下的泥土之多,简直把我吓坏了。我这般惊恐,当然不是没有理由的。要是塌方时我正在洞内,那我肯定用不着掘墓人了。这次灾祸一发生,我又有许多工作要做了。我不但要把落下来的松土运出去,还安装了天花板,下面用柱子支撑起来,免得再出现塌方的灾难。
