| 3. | The periodic output amount of fabricated water from a double - chamber floating bed in one company had greatly reduced , the main cause is the incoming water quality not tally with the originally designed indices 摘要某公司双室浮动床周期制水量大幅下降,其主要原因是进水水质与原设计指标不符。 |
| 4. | After analyzing the basic variation regularity of tongguan elevation , it is pointed out that the amount of incoming water during flood season is the main factor to influence on tongguan elevation 指出汛期来水量的多少是影响潼关高程的主要因素, 1986年以后汛期来水量的大幅度减少是潼关高程持续升高的根本原因。 |
| 5. | This paper deals with the characteristics of incoming water and sediment and changes of tongguan elevation since sanmenxia reservoir began its storing clear water and releasing sediment operation mode 本文阐述了三门峡水库“蓄清排浑”运用以来入库水沙的特性和潼关高程的变化,对潼关高程非汛期升高、汛期降低的基本规律进行了分析。 |
| 6. | The incoming water brings silt with it into the pond . this silt settles onto the pond floor and needs to be removed or else the pond will dry up . as a result , the reserve s dredger is now busy clearing the silt from the channels around the perimeter of 沿岸湿地会被淤泥堵塞,逐渐变为乾地,这是自然现象,米埔亦难以避免:当基围换水时,淤泥随流入的水冲进塘内,并积聚塘底,若不清理,水塘终会乾涸。 |
| 7. | ( 4 ) the dike breach risk of the south bank is relative higher in wandering reaches . ( 5 ) the dike breach risk of the north bank is higher than the south bank in winding reaches . simultaneously , the evaluation results manifest that the evaluation indexes system established from the locomotion of incoming water and sediment load , the regional crustal stability , the evolvement of river regime and the stability of river dikes , can reflect the actual situation of hang river in the lower yellow river more fully 评价结果同时表明,从水沙运动、区域地壳稳定性、河势演变和堤防稳定性4个方面建立评价指标体系,能够更加全面的反映黄河下游悬河的实际情况;运用多层次模糊综合评判法能够较好地解决影响因素众多、作用机制复杂的悬河决溢风险问题;运用gis技术强大的空间分析功能,使黄河下游悬河不同空间位置的决溢风险得到了量化,可以客观地反映黄河下游河道不同空间位置决溢风险的差别,对于指导防洪和河道治理的实践具有重要的现实意义。 |
| 8. | Abstract : by analyzing the changes of incoming water and sediment in the lower weihe river , in allusion to the question of flood discharge capacity being not enough , control project being short , river pattern can ? t being controlled and the management being loose etc , advise to increase the investment , consummate the measures of flood prevention engineering and non - engineering . strengthen the management , consolidate the consciousness of flood prevention and disaster alleviation , in order to raise recent ability of flood prevention in the lower weihe river 文摘:通过对渭河下游来水来沙变化的分析,针对现状堤防过洪能力不足、控导工程少、河势得不到控制和管理工程等方面存在的问题,提出应加大投入力度,完善防洪工程措施和非工程措施,加强管理,强化防洪减灾意识,提高近期渭河下游防洪能力。 |
| 9. | By the analysis and study , it is showed that : 1 ) the lower weihe river main channel was at a balanceable state between aggradation and degradation and floodplain of the lower weihe river is a tiny aggradation state before the construction of the sanmenxia dam ; 2 ) the severe aggradation of the lower weihe river bed is mainly caused by the increasing riverbed elevation at tongguan after the construction of the sanmenxia dam ; 3 ) the main reason leading to the increasing riverbed elevation at tongguan is the unreasonable operation of the sanmenxia reservoir ; 4 ) the rate of the riverbed aggradation at tongguan reach and the lower weihe river reach are speeded by adverse condition of incoming water and sediment recently 然后以实测资料为基础分析研究了三门峡建库前后潼关高程的变化规律以及渭河下游河道的冲淤演变规律,分析研究表明:建库前渭河下游主槽处于动态冲淤平衡状态,滩地处于微淤状态;建库后,渭河下游河道发生严重淤积主要是由于潼关高程的抬升造成的;潼关高程的抬升主要是由于三门峡水库的不合理运用造成的,近期不利的水沙条件加剧了潼关河床的抬升速度和渭河下游的淤积。 |
| 10. | In this paper , the deposition evolution process in qtx reservoir are studied , the incoming water and sediment , the operation data , and the time and space distribution of longitudinal and lateral sedimentation in reservoir are analyzed in detail , and the longitudinal scouring and sedimentation and lateral deformation law in reservoir tidal flat and mainstream under different operation way are summarized in every operation period 本文以黄河青铜峡水利水电枢纽工程水库淤积演变过程为研究对象,对青铜峡水库来水来沙组成、水库运行资料、水库纵横向泥沙淤积时空分布等进行了较详细的分析,总结了青铜峡水库各个运行时期不同运行方式下水库滩槽纵向冲淤和横向变形规律。 |
