Concrete filled steel tube ( cfst ) arch bridge is a new type of bridge which is widely applied in china recently , and it is a relatively ideal structural form for long span arch bridge . with the background of the practice of liantuo bridge , in the view of point of feasible in technology and reasonable in economy , the key techniques and difficulties in the construction of cfst arch bridge are analyzed and discussed in the thesis . the disadvantages in the current design and construction and the improvement method are also indicated 本文以莲沱特大桥工程实践为背景，以主拱施工研究为主线，对钢管混凝土拱桥重难点施工工艺，从技术上可行、经济上合理的角度出发，详细的进行了分析阐述，并指出了设计施工中存在的不足和今后需改进的方向；通过对钢管混凝土拱桥施工过程中内力的计算，确定了拱肋施工最不利荷载工况下加载重量、压重顺序和张拉临时预应力束等一系列施工措施，并将计算结果与现场监测观测数据进行了比较分析，为今后进一步研究这类结构提供了参考。
According to practical technique , better economic index , nearing the main electrical net shelves and focusing on electrical load , we determine overall arrangement of waterpower resource exploitation , select item of waterpower resource exploitation in the near and medium term , raise a blueprint about heilongjiang water - electricity power exploitation and establishment in the near and medium term in order to take reference for relative department 按照技术上可行、经济指标较好、靠近电网主网架和用电负荷中心区域的原则，确定水能资源开发总体布局，选择出近中期水能资源开发与利用项目，对近中期我省水电工程开发与建设提出一个构想，供有关部门决策参考。
The result of experiment shows : the combined process of composite potassium permanganate and powder activated carbon has excellent efficiency of enhanced coagulation and is more advanced than pre - chlorination , which can completely replace pre - chlorination and is not only feasible in technology but also remarkable in economic benefit 试验研究结果表明：高锰酸钾复合药剂与粉末活性炭联用具有优异的强化混凝效能，能够完全取代预氯化并获得比其更佳的混凝效果；该项强化混凝工艺不仅技术上可行，而且具有明显的经济效益。
Secondly , their aims are made the investment of substations , feeders or running cost of electric power system minimum . but they do n ' t take into account of land utilization , street accessibility of right of way , etc . , but demands of electric power system . generally , a straight line distance , namely , euclid distance , was used for calculating the distance between a load point and a substation , which is a straight forward but non - practical way for most planning techniques 其次受研究工具的限制，这些模型以工程投资、运行费用等最小为目标，仅能考虑导线载流量、电压降等电力系统技术约束条件，简化略去了用地限制、街道可达性等重要的自然约束条件，且求解这些模型的前奏是计算负荷点到变电所的欧几里得距离(直线距离) ，简便但不切合实际(这一点在城市电网规划中尤其重要) ，因此较难给出技术上可行的最优解。
The method that mmds wireless digital television overcastting based on catv standards is not only usable in terms of techniques and credible in quality , but also the industrious in investments , and the simple establishment , maneuverability of the method has been proved in practice , which will discussed in the paper in details . the operation results of liling practicality is appropriating which works on the only catv network operating platform 经实践证明,基于有线电视标准的mmds无线数字电视覆盖,不但在技术上可行,质量可靠,而且投资少,经济可行,延伸覆盖简单方便,在一个有线网络的运营平台上,可操作性强,在醴陵试点的实际运营状况也很理想。
Article 3 the term " energy conservation " as used in this law means : enhancing management in the use of energy ; adopting measures which are technologically feasible , economically rational , and , by reducing loss and waste at every stage from production through to consumption of energy , environmentally and socially acceptable in order to use energy more efficiently and rationally 第三条本法所称节能，是指加强用能管理，采取技术上可行、经济上合理以及环境和社会可以承受的措施，减少从能源生产到消费各个环节中的损失和浪费，更加有效、合理地利用能源。
The ground base of the newly added chute in 4 tailings reservoir at dexing copper mine is characterised by thick weathered layer , loose structure , fractured zone and landslip mass accumulation . as a result , the ground has a great subsidence and inefficient carrying capacity . in view of this , the grouting technology was adopted to reinforce the chute ground base . the on - site testing shows that the subsidence of the chute has been efficiently controlled and the carrying capacity of the ground base improved so that the stability requirement has been met 针对金山店铁矿余华寺采区的开采条件:拥有独立的开拓系统、产量不大、装备水平不高、矿岩松软破碎、地压大等,进行了无底柱分段崩落法采场结构参数的优化研究.通过室内物理、数值模拟和现场工业试验,探索出合理的分段高度、进路间距、放矿步距等参数,以求达到技术上可行经济上最优.该研究成果在矿山的应用中取得了可观的经济效益,为其它类似的中小型冶金矿山探索出一条提高经济效益的途径
