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
Observation and analysis of the river bed scour behind the third dam of gutianxi 古田溪三级大坝下游河床冲刷原型观测与分析
The laws are as follows : 1 . the rupture of the tile reinforcement wo n ' t happen in the whole structure ; 2 原型观测中得到如下结论: ( 1 )结构中拉筋不会产生拉断破坏。
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。
Design of earch and rockfill dams project supervision observation design data analyses . evaluation of quality and safety of dams soft foundation improvement 土石坝的设计、施工监理、原型观测设计、资料分析及其大坝的质量和安全评价。松软地基和坝身加固处理技术。
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。
This paper has done the indoor test of the frictional property of the reinforced earth , and the prototype measurement and calculation with finite element method of the single level super high reinforcement retaining wall located in panzhihua city 本文进行了室内拉筋摩擦性质的研究,对攀枝花市三中运动场单级超高加筋土挡墙进行了原型观测和有限元计算分析。
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。
Based on the investigation and statistics of the damage to the wharf structures , the characteristics of the damage were summarized and the causes of the deformation were theoretically analyzed , which were verified by field observation and mathematic models 通过对破损状况的调查统计,总结出了破损的特点,对破损的原因进行了理论分析,并用原型观测和数模计算结果进行了验证。
Some researchers have made study on this subject , such as the generation and evolution of frazil ice , shore ice , bottom ice , ice cover and ice jam , the resistance of freeze - up river , flow capacity and variation of water stage 国内外一些学者通过原型观测,试验和数值模拟的方法对水内冰,岸冰,底冰,冰盖和冰塞的生成和演变,封冻河道的阻力、过流能力和水位变化等有关问题进行了研究。
