| 1. | Hydrological prototype observation of two phase river closure in nierji reservoir 尼尔基水利枢纽二期截流水文原型观测 |
| 2. | But for the poured asphaltic concrete ( pac ) , it is only in the testing stage and lacks systematic a anlyses and prototype observations 而浇筑式沥青混凝土处于试验阶段,缺少系统地研究和原型观测。 |
| 3. | As no flexible field load test has been developed , prototype observation and numerical analysis are reasonable way to study composite foundation under embankment 目前还没有在柔性荷载下进行现场试验的方法,加强现场测试和计算分析是探讨路堤下复合地基工作性状的一种途径。 |
| 4. | Prototype observation and model experiment indicate that flows in two channels of the discharge passage of an axial - flow pump and a guide vane mixed - flow pump are unequal to each other , there is flow deviation 摘要原型观测和模型试验都表明,轴流泵和导叶式混流泵双孔出水流道两孔流量不等,存在偏流。 |
| 5. | The prototype observation shows that because settlement of soil is larger than that of piles , " arch effect " appears in the embankment so that its weight is gradually transferred from the soil to piles and pile - soil stress ratio increases 现场原型观测表明,桩间土的沉降量大于桩顶的沉降量,填土中出现拱效应,填土荷载逐渐从桩问土向桩顶转移,桩土应力比逐渐增加。 |
| 6. | According to all kinds of data obtained from prototype observations system , this article examined the research results and data , it provides the theoretical and practical support for the construction of deep water and high dam in yellow river delta soft land area 根据大坝原型观测系统观测的各种数据,对研究的结果和得出的数据进行了检验,为黄河三角洲软土地区兴建“深水高坝”提供了理论和实践的支持。 |
| 7. | By means of prototype observation , analysis and numerical model the author analyzed the canal scour and sediment process , the different scour and sediment affected on the discharge and affected on materials movement in different cross sections of the canal 本文采用原型观测、资料分析和数学模型对北引渠道冲淤形态的演变过程,不同冲淤形态对过水能力的影响,断面形态的稳定性对泥沙输移的影响进行了研究。 |
| 8. | Abstract : earth pressure on a anchored pile sheet wall and a reinforced earth retaining wall , are obtained by prototype observation , finite element method and theoretical analysis . the results can be used as reference for lateral pressure of similar retaining structures 文摘:对一座锚拉式桩板墙和一座楔形钢筋混凝土块拉筋加筋土挡墙,将原型观测、有限元计算、理论计算得到的土压力进行分析和比较,所得结论可供设计类似支挡结构时计算土压力参考。 |
| 9. | By means of prototype observation , analysis with materials and theories , and laboratory test , the author deeply analyzed the causes and procedure of canal cross section erosion , and obtained eight causes which resulted the canal deform including flow , seepage , runoff , collapse of bank , dry effect , human activity , wave flush , frozen , and then stressed to discuss the frozen process 本文通过原型观测、资料分析、理论分析、室内试验对北引渠道变形的成因和发生机理进行了较为深入的分析研究,给出了造成北引渠道变形的八大原因:流水引起的变形、渗透引起的冲刷、地表径流引起的冲刷、滑坡变形、干燥作用、人类和动物活动的影响、风浪引起的冲刷、冻融侵蚀,并着重阐述了冻融侵蚀的机理。 |
| 10. | Based on the prototype observation and model test made for the periodic - flushing de - silting basin , the process and the division of the three - stage hydraulic flushing are put forward on the basis of the feature of water - sediment movement , and then the calculation formulas and the related parameters for the stages of emptying flushing ; retrogressive flushing and the flushing along the basin are given as well 摘要依据定期冲洗式沉沙池水力冲洗的原型观测和模型试验,根据水沙运动特征,提出定期冲洗式沉沙池水力冲洗三阶段冲洗过程及划分,分别给出泄空冲洗、溯源冲洗和沿程冲洗各阶段的计算式和有关参数。 |
