1、Rapid construction of the embankment damAbstract : In recent decades, the soil core rockfill dam has gradually become the worlds construction of the high dam-one of the mainstream, With the new earth and the huge investments in machinery and construction technology of filling a higher level, Meanwhi

2、le dams in-depth testing, greatly expanding the embankment dam scope of the materials and the use of materials for model for more extensive embankment dam will provide favorable conditions to change the long-standing embankment dam with a long construction period, Filling the lack of low intensity,

3、and further accelerate the progress of the construction, Filling in ensuring construction quality and safe operation under the premise to explore the rapid construction of embankment dams it is very necessary thing. Key words : embankment dam Rapid construction Construction1 Overview Also known as t

4、he embankment dam dam local materials, the necessary soil in situ stone mining in general, but can also make full use of the excavated material. having to basic requirements, low deformation based on the character, filling construction, and can be divided into RCC-grade. Fill-rockfill dam, direction

5、al blasting rockfill dam, the hydraulic fill dams, hydro-filled dam and masonry dam in different ways. Parabolic which administered rockfill dam no longer, directional blasting rockfill dam late settlement exist, not be planted within the dam prototype observation equipment shortage, which are rarel

6、y used, hydraulic fill dams, Fill the water main in a special area of the lower dam height of the small and medium projects, the masonry dam strictly speaking belongs masonry dam category, At present, the extensive use of thin sections and the hierarchical compaction roller compacted embankment dam.

7、 2 The need for rapid construction With the dam construction technology, concrete gravity dam dam the technology continues to improve, while the rubber dam and other new dam-constant use, there is a traditional embankment dam filling a large quantity of a long time to build the shortcomings become e

8、xtremely prominent, how to fully exploit the technology itself embankment dam low, right foundation adaptability, full use of local materials to the traditional advantages to speed up the construction schedule, as Pa-an important option. Filling in ensuring the quality of construction and safe opera

9、tion of the rapid construction premise is that the parties are concerned. 2.1 Based on the uncertainty, the need to accelerate the progress of measures With the hydropower development progress in basic bad place to build a large embankment dams, In order to meet the capacity and infrastructure found

10、ation impervious to the needs, often based on the completion of treatment can only be reclaimed after construction, however, foundation of a more complicated, especially in deep-cover construction projects, infrastructure projects are large, unpredictable factors, often need cutoff Vibroflotation, c

11、urtain grouting, grouting consolidation of the foundation for the integrated treatment, handling difficult and complex examination, Based on the number of projects, foundation treatment completion and handover of face time is often more work plan by the time lag. Filling started causing delay and th

12、e next gate or the completion of water storage often not be adjusted, resulting in an effective filling time, Construction units have had to resort to quick construction of measures will be scheduled according to the contract （or even ahead of） completion of the project. 2.2 Hydro-meteorological, fi

13、lling intensity of the proposed new standards Embankment dam of the hydro-meteorological factors are extremely sensitive and in the rainy season, soil moisture greatly influenced, directly restricts dam reclamation, construction intensity will be affected; winter, the soil on the cold, and if it doe

14、s not take active measures is impossible to filling and filling winter rainy season, there is a high input, low output of the predicament, Construction units are often reluctant to assume, therefore, take full advantage of filling the golden season, try to avoid winter construction of the rainy seas

15、on （or reduce the amount of filling winter rainy season）, the construction unit is the first choice of the relative, the filling the quantity of work is often very substantial. Rapid construction can be avoided winter rainy season generous amount of filling the most important issue. 2.3 New Construc

16、tion equipment and materials massive expansion of the scope of application is the basis for rapid construction With the improvement in the degree of mechanization, large capacity of earth and equipment used in construction, improved ergonomics, thus laid for the rapid construction of the necessary material foundation for the formation of materials to expand the scope of application. the original dam material unsuitable materials can
