土壤-根茬复合体其抗剪强度与剪切面上的法向压应力成正比，复合体土壤凝聚力c比无根土壤增加115 205 ；内摩擦角增加11 15 。 - On basis of experimental analysis , several conclusions can be indicated that : roughness of cement face or structural plane can be described well quantitatively with fractal dimension in paper . roughness increases inner friction angle and cohesive force , and transfers characteristics of shear deformation curve and mechanics and form of shear failure
试验研究及分析表明，文中方法确定的分维数可以用来较好的定量描述结构面或胶结接触面的粗糙程度；粗糙度的存在，提高了胶结面的内摩擦角及凝聚力，改变了胶结面剪切变形曲线特征及剪切破坏机理和形式。 - At first it analyzes the bedding rock slope ' s bedded rock and its incontinuity face , and studies the stress , strain , stability ' s condition of the bedding rock slope , fully considering the cohesive force of rock layer and incontinuity face . geologic mechanics models of two types of bedding rock slope are set up , the instability coefficient of bedding rock slope under different mechanical parameters is computed , and the conclusion that the stability of bedding rock slope is relation to rock layerer , cohesive force of incontinuity face , inner friction angle and rock layer obliquity has been gotten . based on the above discussion , the thesis comes down the influence of rock layer and the incontinuity face on the bedding rock slope to incontinuity face ' s influence factors , and discusses other factors that influence the bedding rock slope ' s stability , so gains the evaluating and forecasting index marks
本文首先对顺层边坡的层状岩体及其中的层理面和不连续面进行了分析，对其应力应变进行了研究，得出了顺层边坡的稳定性不仅与岩体中岩石的强度有关，还与岩体中层理面及不连续面的内聚力、内摩擦角及其倾角有关；论文建立了层理面和节理面的地质力学模型，讨论了其力学参数变化对边坡稳定性的影响，并在此基础上将层理面和节理面归纳为顺层边坡稳定性的结构面影响因素，同时讨论了影响顺层边坡稳定性的其他因素，从而得出顺层边坡稳定性的评价预测指标。 - The retaining wall reclining on the slight slope built on soft foundation is usually used in protecting the shore of river , the contradiction between the lack of impartiality in stress of the base and the small stress allowed by the foundation as well as the lack of stabilization of the breast wall is a hard nut to crack in the engineering . in the paper , a tenon - base is added under the base of the retaining wall , on the study of the choice of the parameters and formulas used in calculation and the research of theory used in calculation , method used to deal with the load , etc , the writer gives a way to crack the nut mentioned above paragraphs and presents a qualitative and quantitative analysis about them , such as the equivalent inner friction - angle ( d ) and the passive press of the clay ( ep ) , etc . in the end of the paper , using modern optimization method , a design of the retaining wall reclining on the slight slope built on soft foundation is done , the result is economical , and accords with the fact
软基上的仰斜式挡土墙在水利工程河道护岸中经常遇到，仰斜式挡土墙基底偏心应力较大和软基土地基容许承载力偏小的矛盾以及挡土墙抗滑稳定不足是工程中难以解决的难题。本文在对仰斜式挡土墙设计中有关计算参数的选择、公式的选用应该注意的问题进行了研究，对河道护岸软基础上的仰斜式挡土墙采用凸榫基础处理的方法，就其计算理论、设计验算中各荷载的具体处理方法进行了较为细致的研究，提出了解决软基础上的水工仰斜式挡土墙难以解决的难题的方法，并对有水情况下粘土等效内摩擦角_ d 、凸榫被动土压力e _ p等在计算中的取值提出了定性和定量的分析。最后利用现代优化方法对软基础上的水工仰斜式挡土墙进行了结构优化设计，得出了符合实际的结果，与其它重力式挡土墙形式进行比较，取得了明显的经济效益。
