Analysis on Collapse Geological Disaster Management Project in Nuozhuang Village in Rizhao City in Shandong Province
Collapse geological hazard points in Nuozhuang village in Houcun town in Donggang district in Rizhao city has a large height difference and steep slope.From 1998 to 2021,local collapses have happened many times,and caused road and house damage.It will seriously threaten the safety of people's lives and property.In this paper,by using technical means,such as on-site investigation,geological surveying and engineering survey,main causes of instability in collapsed bodies have been identified,and the stability has been analyzed.By using the circular arc sliding slice method,the slope stability coefficient is calculated as 0.761.It is indicated that the slope is in an unstable state.After taking engineering treatment measures,such as slope trimming,masonry of retaining walls,interception(drainage)ditches,protection and green-ing engineering,the stability of the slope surface has beem calculated.The treated slope can meet the sta-bility safety factor required by the specifications.The economic,social and environmental benefits brought about by geological disaster control engineering are highlighted.
