The Character Of Geological Diseases And Preventive And Controlling Measures Of Xiangning-Ji Xian's Part Of Highway From Linfen To Jixian

Highway from Linfen to Jixian, the part from Xiangning to Jixian , which is an integral part of the road from Qingdao to Lanzhou that is the National important pla nning highway.The expressway is located in the Loess Plateau of West Shanxi area , larger topo graphy, geomorphology unit complex, especially in areas covered by loess gullies criss -cross, slope rise steeply, there are a lot of geological disease.This article is in the preliminary geological exploration works through a series of comprehensive surveys, the initial identification of the lines about the topography, geomorphology, surface water, hydro-meteorological, stratigraphy and lithology, geotechnical engineering classification, hydro-geological conditions, geological structure earthquakeintensity and the stability of the region; a preliminary identification of distribution ofgeological diseases, of geographical and geological background, to describe the characteristics of geological disease. Analysis of the causes of disease, and hazards on the project, giving prevention and control measures about hazard.This article reads as follows:First of all, according to the results of geological investigation, a detailed descript ion of landforms and geomorphology; identify the source of surface water and traffic, the region's hydro-meteorological; identify stratigraph and lithology in the region, geote chnical engineering Category , hydro-geological conditions and geological structures, se ismic intensity and the stability of region.And confirm the type of disease in the road, through the investigation of geologi cal painting, surveys and studies the context of natural geography and geology of geol ogical diseases carefully. Through surveys and drilling, identify the all sizes of geologi cal diseases, and a detailed analysis of the geological causes of disease and stability.Analysis of hazard of geological disease in the engineering segment, give the geo logical disease prevention and control measures.Finally, we taking more comprehensive exploration to goaf , using the means of geophysical survey to the road with goaf and to determine the distribution of goaf ran ge, and then verify by drilling. The delineation of mined-out area and make the corre sponding control measures.
