1、河北工程大學(xué)碩士學(xué)位論文馬頭發(fā)電廠灰壩材料試驗與工程特性研究姓名：李峰申請學(xué)位級別：碩士專業(yè)：水工結(jié)構(gòu)工程指導(dǎo)教師：李彥軍2011Abstract IIAbstract Ash field is to solve the problem of fly ash storage, protecting the environment and construction. Ash Field Ash Dam

2、 is the main building, is also an important part of thermal power plants. Recent years, with the growing number of thermal power plants and the increasing expansion of the scale, along with

3、ash dam technology has become more sophisticated. Or is the use of fly ash dam heightening fly ash dam, with investment, quick returns, significant economic benefits characteristic of ash dam

4、construction has become a new trend. However, the current technology is still in an ash dam engineering practice ahead of the state of design theory, and some technical problems in the theory

5、 can not give a satisfactory explanation. For example, superposition of filling stage the stability of the ash dam, seepage state of the sub- dam construction in the direct deposition of ash,

6、 the ash dam safety how to, sub- dam foundation is required to do a special foundation treatment. In this paper, four power plants in Handan gray matou field heightening project, for example,

7、 on the ash dam heightening project of the dam material, the physical properties of ash deposition and dam seepage and static and dynamic stability of the dam thematic studies . The main con

8、tents of this paper and results are as follows: (1) conducted a more comprehensive geological characteristics of ash dam project evaluation, made for Ash Seepage and stability analysis of a ty

9、pical engineering geological profile; (2) the use of Seepage hydraulics theory, took the child under water retaining dam of different transient seepage Ash Dam. Analysis showed that: the main a

10、nd sub- saturation line elevation lasted retaining dam, the dam material permeability and drainage facilities about. (3) During the obtained sub- retaining dam, the length of dry beach, fly ash

11、permeability, anisotropic permeability on the saturation line were investigated. (4) Application of the Study of Sweden and the Bishop method of dam in the typical conditions for the stability

12、 of checking. The theoretical analysis and experimental results on the actual dam construction in the water body in the form of ash, and the slope rate of the selected location has certain r
