摘要
基于西宁市中心城区气象观测站2016年～2018年降水、风力、温度、湿度和气压等资料,对西宁市南山西坡滑坡体变形自动监测站地表位移数据进行相关性分析,建立回归模型。研究表明,高原地区滑坡位移与降水呈正相关趋势,即降水量越大,滑坡位移量越大;与风力、温度、湿度关系近似对数函数曲线,受影响至一定程度后不再明显增大;受气压影响微弱,可忽略不计。所建立滑坡回归模型在气象单一条件下有较好适用性,对于研究和预测滑坡灾害有重要意义。
Based on the precipitation,wind,temperature,humidity and atmospheric pressure of the weather observation station in downtown Xining during 2016-2017,correlativity analysis of the surface displacement data of the automatic monitoring station of the landslide body at the southwest slope of Xining was carried out,establish a regression model.The research shows that there is a positive correlation between landslide displacement and precipitation in the plateau area,which is the greater the precipitation,the greater the landslide displacement.Approximate logarithm function curve with wind force,temperature and humidity,no longer significantly increased after being affected to a certain extent.Affected by the pressure is weak and negligible.The landslide regression model established has a good applicability under the meteorological single conditions,it is of great significance to study and predict landslide hazards.
