Study Of The Karst Area Roadbed Disease Survey Techniques And Treatment Options

The modern high upgrowth of matter culture and quickly development of science and technology, provide the necessary foundation and measuration for prevention of the nature disaster. But the nature disaster also raid the human being more severely. Since the 50's, because of swift development of human engineering maneuver, the karst conceal in the subterranean sinks also emerges as the times require. The frequency that happens is more and more great against intensity .The perniciousness is also broaded at the same time.The road construction in the development of the west possessing the position holding the balance. The geological situation of west area in our country is complex , The geology diseases such as limestone cave and so on are numerous. In the course of road prospecting and the constructing process, Urgently necessaries are a suit of limestone cave geophysics detecting means and technique are researched, which have effectual high degree of accuracy (comprise else geology disease) .the result may toguide that the expressway roadbed handles.Full text is total to six chapters, Summary is as follows:Chapter 1, The origin is clarifyed that the dissertation depends on.Uniting the backdrop of this research, study aim and sense were proposed.The content, working means and process that relates to that research are Planned.Chapter 2: Summing up the present technical research development and the application of cavity in home and abroad, Forecast to its foreground moreover. Compare to other geophysics means,geophysics tomography technology Have distinctive preponderance and action.It is fit for the detection of subterranean karst and subterranean struction.Chapter 3, Elaborateing of fundamental theory of geophysics and laying stress on acoustic wave tomography and electromagnetic wave tomography. To seek the equation resolution, trace to the beam?Grid discretization?Optimal path algorithm? the iterate of equation the algorithm comparison are Sumed up the integrated tomography process through System analysis and research carried on.Chapter 4,According to the engineering-geology problem of Karst roadbed, we have a research on the stability and disease processing scheme of the roadbed .Chapter 5,The experimentation and detecting work have been carried on the expressway of chang(de)-zhang(jiajie).The experiment indicate that the reconnaissance have taller accuracy and dependability through the syntheticalgeophysics technology which combined with engineering geology.Chapter 6, On the base of experience work, we evaluate the geophysics technology that have been used .the actual application means combination are Summed up. finally, we Propose the optimum method and the work pattern of cavity prospecting.Chapter 7, The acquaintance and conclusion to karst reconnaissance are Proposed.finally,we sum up the rule of surveying.
