不均匀沉降灾害特征分析及变形预测研究OA

To lay the theoretical foundation for the prevention and control of uneven settlement disasters,this article combines the results of on-site investigations to first analyze the development characteristics of uneven disasters,and then evaluate the development trend of disasters through deformation prediction.The analysis results show that according to on-site investigations,the disaster area can be divided into three deformation zones,with significant deformation characteristics,all of which are temporarily in an unstable to basically stable state.If under ex-treme rainfall conditions,there is a possibility of instability,and the degree of harm is significant;Meanwhile,through deformation prediction,it was found that the subsequent deformation rates of JC16 to JC18 range from 0.33 to 0.57mm/period,with a significant increasing trend,in-dicating that their cumulative deformation will continue to increase.Therefore,research on non-uniformity prevention and control needs to be carried out as soon as possible.
