1、成都理工大學碩士學位論文淺層地震氣折射波法在工程應用中的研究姓名：王奇申請學位級別：碩士專業(yè)：信號與信息處理指導教師：王緒本20100501Abstract IIIA study of application of shallow seismic refraction methods in engineering Introduction of the author: Wang Qi, male, was born in April,

2、 1980. whose tutor was Professor Wang Xuben . He graduated from Chengdu University of Technology in Signal and Information Processing major and was granted the Master Degree in June,2010. Abstract Shallow seismic refract

3、ion wave method is put forward from the 1930s, have been widely applied in engineering geology survey, whether in the field gathering, material handling equipment to explain or in theory of basic research method has a tr

4、emendous progress. With other geophysical exploration methods, data quality is a foundation, and material handling, they are the key for geological interpretation is most important. Especially in the collection of the da

5、ta is not very good circumstances, data processing, plays a more important role. Although influence factors of refraction wave interpretation accuracy, but there are many methods to choose reasonable explanation to impro

6、ve precision of exploration, is a kind of effective method. Papers on the theory of shallow seismic exploration and refraction wave interpretation method on the basis of research, this paper analyzes the research method

7、of 0 t , the method of surface stripped and Hales. Think of surface strip method can underground structure can give detailed analysis, But as the underground structure complicated, its analytical error is also increased

8、. Because it uses the negative direction from the wave, in different places in the interface of the reflection refraction and reach the surface produces the same observation. According to this problem, use from the same

9、sites reflecting interface strata formation of refraction wave came, and to reduce the reflector and because the formation and the error caused by this method, namely, Hales, but we discovered that method by the method o

10、f rice surface rolling, it is great influence on refraction interface extremely rules or buried deep can give good effect, Because of its application is the method of 0 t approximate an isosceles triangle high as the d

11、epth of the interface for refraction refraction interface level or curvature not too big time is more accurate. Based on the practice of work, his adopted for some application examples above three methods were analyzed.

12、 In the process of railway construction in different complex geological conditions emerge in endlessly, covering layer thickness in the approaching or over 100m and the bedrock surface Angle, and more changeable recessiv
