基于长观水位及历史降雨量的建筑抗浮水位取值研究
Research on the water level of anti-floating of building structure based on long-term boreholes and rainfall observations
摘要
Abstract
This paper studies anti-floating groundwater level of main body structure foundation pit,with a case study of the metro line 2 at Sanqiao station,Guiyang.The relationship between long-term groundwater level monitoring data and rainfall data was analyzed.On this basis,a method for the calculation of anti-uplift water level values was put forward.Main result shows that,(1 )anti-uplift water value consists of three parts,i.e.the highest groundwater level during the site investigation,the groundwater level rise by unex-pected recharge and the maximum groundwater fluctuation rate compared to that of the site exploration peri-od;(2)The groundwater levels monitored fluctuate seasonally which commonly increase in rainy season and decline in dry season,with the highest water levels appear in June and July;(3)The linear relationship be-tween the change of the groundwater level and the change of monthly rainfall was obtained by the linear fit-ting of the rainfall in April,May and June;(4)Combined with the historical rainfall,the maximum increase of the groundwater level in the field area is 2.26 m,and the anti-floating water level in the field area is 1,128.46 m.关键词
