During the construction of the concrete lining for the diversion tunnel of xiaowan hydropower station , the concrete linings for the sides and the crown of the tunnel are simultaneously placed by the integral steel shuttering trolley with the greatly shortened construction progress 摘要小湾水电站工程在导流洞混凝土衬砌施工中，边顶拱混凝土采用整体式钢模台车一次衬砌成形，大幅提高了施工进度。
The field quality check showed that such technology can meet the requirements of design and compared with traditional methods it can simplify the construction process , increase the construction flexibility , quicken the construction progress and reduce project cost 现场质量检测表明，采用该技术可满足设计要求；且与传统方法相比减化了施工工序，加大了施工灵活性，加快了施工进度，降低了工程造价。
Aiming at a weekly output of 12 km , we organize at least four powerful subcontractors , each sub - contractors at least organize 200 labors , conservative calculations , 2 . 5 meters per person a day , also can ensure the construction progress of two kilometers a day 以一周的工程量12公里为目标，至少组织4家有实力的分包商，每家分包商至少组织挖沟劳工200人，保守计算，每人每天挖沟2 . 5米，也能够保证每天2公里的施工进度。
For other decoration application , the dosage of mortar essence shall be 0 . 1 and construction shall be executed pursuant to general criterion requirements ; in plastering mortar , the dosage of mortar essence shall not be increased at will otherwise excessively long coagulation time is required , leading to delay of schedule 其它装修水泥砂浆晶掺量为0 . 1 ，按通常规范要求施工，抹灰砂浆不能随意增加掺量，否则会造成凝结时间太长，而影响施工进度。
Aiming at high design requirement and great technical difficulties , construction methods such as blasting control , excavating and mucking in the tunnel and grout injection in the holes with anchor have been improved on so as to advance construction efficiency , quicken construction schedule and increase economical benefits finally 针对此工程设计要求高、技术难度大等特点，对爆破控制、洞室开挖出渣、锚杆注浆等施工方法进行了改进，提高了施工工效，加快了施工进度，最终提高了经济效益。
The static loads were placed step by step in time sequence in order to simulate the construction conditions of the dam during the calculation . the results of the analysis show that excess pore water pressure would not appear in the design section during the analysis results that the dam was statically stable and the construction process was reasonable 在静力分析过程中采用在时域上逐步加载的方法，模拟了坝体的施工填筑过程，计算结果表明，设计断面在贮灰过程中不会产生很高的超静孔压，坝体静力稳定状态较好，施工进度合理。
In order to simulate the construction process and the effect of concrete pouring temperature and outside temperature on temperature field and thermal stress field in the dam , temperature field and thermal stress field are calculated layer by layer . the calculation step during construction is 0 . 25 day , and during operation the diffusion of hydration heat of concrete is over and elastic modulus is basically stable , changeable step is used 为了研究施工进度、混凝土浇筑温度、外界温度对坝体温度场和应力场的影响，按碾压混凝土施工方法每浇筑一层(层厚0 . 3m ，浇筑时间6小时)计算一次温度场和应力场，这样，施工期计算步长为0 . 25天，运行期因混凝土水化发热已结束，且弹模基本稳定，故采用变步长计算。
In this paper , referring to qingju water power station , temperature control analysis and study has been done : study on the match ratio of the concrete and question of modifying of the special fine sand concrete to improve resisting ability of splitting of concrete ; study on the technology of the highly mixed fly ash to reduce the adiabatic temperature rise of concrete ; in case of the condition of resisting splitting to allow , study on the temperature control measure to strengthen and water the size of building , simplify the operational procedure , accelerate the construction speed , economize the expenses of the project 温控问题成为青居水电站设计和施工的关键技术问题。 、本文对水工大体积混凝土温控问题进行了分析和总结，结合青居水电站闸坝工程，开展温度应力及温度控制研究:研究混凝土的配合比及特细砂混凝土‘改性问题，提高混凝土的抗裂能力;研究高掺粉煤灰技术，降低混凝土的绝热温升:在抗裂条件允许的情况下，研究施工过程中温控措施的简化，以加大浇筑尺寸，简化施工程序，加快施工进度，节约工程费用。
