破裂岩体相对位移监测值的温度影响及校正——以链子崖危岩体相对位移监测为例

Temperature effect to results of ralative displacement monitoring in fracture rock mass and its correction

文章从资料处理分析和岩体稳定性预测预报需要的角度出发 ,分析探讨温度对岩体相对位移监测结果产生的各种影响 ;着重就岩体本身和仪器混凝土底座因温差引起的膨胀变形进行了量化分析 ,提出了相应的校正方法。

Based on data analysis and the forcast need of rock mass stability,this paper analyes all kinds of influence to ralative displacement monitoring results caused by temperature difference.The expansion deformation of rock mass and equipment concrete base has been analized in quantification.The methods for correction have been put forwand.In the end correct effect has been tested according to monitoring example of Lianziya dangerous rock mass at Three Gorge.
