Study On Geological Disaster Assessment And Prevention Measures In Fushun Area Of Liaoning Province

Fushun is an important industrial base in Liaoning Province.There are many important projects built or under construction in the area.In recent years,human engineering activities are frequent,slope stability is seriously affected,and the corresponding protective measures are less.In heavy rainfall,collapse,landslide,debris flow and other geological disasters occur frequently,seriously threatening the safety of important projects and people's lives and properties.Therefore,it is of great significance to evaluate the risk of landslide.This paper takes Fushun area as an example,through a comprehensive investigation of the geological disaster situation in this area,and on the basis of collecting relevant data in detail,combined with mathematical modeling methods and software such as Sufer to carry out regional geological disaster zoning and risk assessment.Finally,the paper gives the suggestions of regional control and monitoring prevention of geological disasters in Fushun area.The following achievements have been achieved:(1)The regional geological background conditions for the formation of geological disasters in Fushun County and Fushun City are basically investigated.Due to the comprehensive influence of many conditions,the types,characteristics,development and harm degree of geological disasters in different areas are different,with obvious regional characteristics,providing the basic conditions for the formation of geological disasters.In view of this,we should fully combine the actual situation,find the root cause of geological disasters,adopt appropriate methods to prevent and control,avoid the occurrence of disasters,and promote the healthy and harmonious development of society.(2)The situation and development characteristics of geological disasters in the study area are basically investigated.Compared with the geological hazard inspection report of Fushun City in 2016 and the geological hazard inspection report of Fushun County,the survey has added 2 geological hazard points(Fushun County),12 geological hazard points(8 in Fushun City and 4 in Fushun County)after verification and cancellation,and 5 geological hazard points(Fushun City).(3)The main factors inducing geological disasters in the study area are preliminarily identified.The occurrence and development of geological disasters in Fushun City are closely related to natural factors such as topography,lithology,geological structure,atmospheric precipitation and human engineering economic activities.The types and scale of geological disasters in Fushun City are mainly medium to large-scale ground fissures and landslides,supplemented by small-scale ground collapse,collapse,debris flow and other geological disasters.The occurrence of the above geological disasters is not only affected by natural factors such as topography,geological structure and atmospheric precipitation,but also controlled by mining,slope cutting and other factors.(4)The susceptibility of geological disasters is divided into different areas.The susfer and modeling method are used to divide the susceptibility of geological disasters in Fushun area.(5)The prevention and control suggestions of geological hazards are put forward,the prevention and control divisions are formulated,and the group survey and group prevention network of geological hazards is established.It has been proved by practice that the division of geological disasters in Fushun area can be effectively carried out by using mathematical modeling and software safer,and the risk assessment can be carried out accurately by using the evaluation model,which can provide services for the geological disaster assessment and prevention and control in Fushun area.
