Research On The Geological Hazards And The Particularity Of Engineering Activities In The Loess Area Of Shanxi

China is one of the most widely distributed loess on the earth,and it is mainly distributed in the Loess Plateau of China.Shanxi Province in the Loess Plateau region,in addition to a small area of rock exposed,the vast majority of the province is covered by loess,is a typical loess area.Due to the dry climate here,precipitation concentration,especially in Shanxi Province and the Yellow River connected part of the region,where soil erosion is more serious,the ecological environment is extremely fragile.Once the damage is difficult to recover in a short time.The terrain of the province from the northwest tend to the southeast direction,the surface runoff and rain erosion and long tectonic movement,in the loess area formed a special loess landscape: loess gully,loess gully and loess potential erosion surface.This landform and human unreasonable transformation of nature,making the geological disasters in Shanxi Province,frequent,landslides,collapse,ground cracks,ground subsidence and other geological disasters occur,to the China cause of a great economic losses.Based on on-the-spot investigation and collection of relevant data,this paper expounds the topography,geomorphology and related features of the Loess distribution area,Investigation of the distribution of loess area of Shanxi province were the typical geological disasters in Changzhi Pingshun county,Xinzhou Wuzhai county and Lvliang Linxian County.Detailed understanding of the survey area climate features,geographical location,geological conditions,and statistics of a number of geological disasters in a certainage,It is concluded that the geological disasters in the Loess distribution areas of our province mainly include small and medium-sized loess collapse and landslide,as well as the ground collapse and ground fissures caused by coal mines.This paper also studies the mechanism of various geological disasters in detail,and describes the classification of various geological disasters according to a certain element,This paper also studies the mechanism of various geological disasters in detail,and describes the classification of various geological disasters according to a certain element,And use the real disaster case to analyze and prove it,and get the various factors of the geological disaster.In addition to investigating the quantity and types of loess geological disasters in Shanxi Province,the paper also makes a systematic exposition of the specificity of various engineering activities and the prevention and control measures of various types of geological disasters in Shanxi Province.Shanxi Province,the main engineering activities,including coal mining,road construction,railway construction and housing construction projects,due to the characteristics of loess in Shanxi Province,making the project activities in the process need to use special engineering measures to solve the corresponding problems.Such as the prevention and control of coal mined areas,the construction of highway and railway side slope protection,roadbed drainage problems and the excavation of pit slope support problems.In the aspect of prevention and control of geological disasters,this paper expounds the principle of prevention and control of geological disasters in the loess area of our province,and puts forward a variety of prevention and control measures in loess collapse,landslide,ground collapse,ground fissure prevention and control,Which has a reliable basis for prevention and control of geological disasters in the loess area of Shanxi Province.
