| 1. | Study on chaos of saturation line of tailings dam based on grey operator 基于灰色算子的尾矿坝浸润线混沌研究 |
| 2. | Analysis of phreatic line monitoring data in auxiliary dam of biliuhe reservoir 碧流河水库一副坝浸润线监测资料分析 |
| 3. | The numerical results by finite element method are in good agreement with the observation ones , which show that the suggested model is useful for researching practical problems 验证计算成果与现场浸润线观测资料吻合良好,表明所采用的数学模型与计算方法是可行的。 |
| 4. | The analysis results show that the technical code for sanitary landfill in china would satisfy the antipollution request of surrounding site and groundwater , on condition that the water level in landfills is limited to a small value 分析结果表明,我国的卫生填埋技术规范对填埋场衬垫的要求是可行的,但还需限制填埋场内的渗滤液浸润线水头高度。 |
| 5. | Another hidden danger is the weakening of the impervious ability of the dam resulting from the closeness of the height of line seepage of the reservoir water level to the contact plane between the residual solum , talus solum and basement rocks 水库水位浸润线标高和残坡积土与基岩接触界面标高较接近,而使此高程的防渗能力更加薄弱,这也是此坝体的隐患之一。 |
| 6. | ( 4 ) on the basis of analysed result and the status quo of huxi bank , computing the slope safety and seepage of bank by fem . the result shows that the tarus quo of huxi bank could not satisfy theslope safety on designed flood lever . after the reinforcement of seepage , the method can not only reduced leakage , debace the soggy but also ameliorate stress fields . lt also can reduce horizontal displacement and certical displacemeng which have disadvantages to bank 进行堤体防渗加固后,不但可以减少渗漏,降低堤身浸润线,还可以有限度地提高抗滑稳定安全系数,改善堤身及地基的应力场,使在高水位作用下产生的不利于堤体安全的水平位移和竖向位移减小。对在后继采动中可能造成的防渗材料的破坏进行了校核,结果表明材料是安全的。 |
| 7. | In view of the technical and safety problems ecnountered in the later - period management of shankoucun tailings dam in meishan iron mine , a series of technical measures were taken to lower the water - table of the dam . as a result , the service life of the tailings dam has been prolonged and the dam has been made to operate in a safe and stable way 针对梅山铁矿山口村尾矿库在后期管理中遇到的技术、安全问题,通过采取一系列的技术措施,降低尾矿坝的浸润线,达到了延长尾矿库使用寿命,从而使山口村尾矿库安全、稳定、顺行。 |
| 8. | The thesis built the relation between containing water and the properties of trail dam ' s soil by geomechanical properties of trail dam ' s soil ; analysed the seep rule of water in the trail dam ' s field and the change of soakage line . the thesis applied the limited element to analyze the trail dam of baogang by the engineering item in production . it calculates the dynamic and static response about the dam using the numerical simulation method 本文通过大量的尾矿土物理力学性质试验资料,建立了含水量与尾矿土性质之间关系曲线;分析了水在尾矿坝区的渗流规律和不同标高时浸润线的变化情况,为分析尾矿坝的稳定性提供依据;结合生产上的工程项目,从包钢尾矿坝的稳定性研究入手,应用有限元法,通过数值模拟分析了水对尾矿坝的静力、动力稳定性影响。 |
