岸坡上某建筑物抗浮设防水位确定分析
摘要:在水位变动条件下,对岸坡上建(构)筑物进行渗流场分析对于抗浮设防水位的确定有着重要作用。为了分析在水位动态变化条件下,岸坡上建筑物的地下水位变化情况,以实际工程中某典型岸坡上建筑物为工程背景,根据饱和—非饱和渗流理论,采用GeoStudio有限元软件,对该岸坡进行了有限元渗流数值分析,分析了该岸坡在水位上升和下降作用下的地下水位线变化规律,得到了在水位变化条件下该岸坡上建筑基坑处的地下水位线变化与坡面至基坑边缘的水平距离之间的关系。为岸坡上建(构)筑物抗浮设防水位确定提供了可靠依据,计算结果可作为该工程抗浮设计的重要参考数据,指导了该项目基坑的抗浮稳定性分析工作。
Abstract:Under the condition of water level fluctuation, the seepage field analysis of the foundation pit on the bank slope plays an important role in determining the anti-floating water level. In order to analyze the change of groundwater level of the buildings on the bank slope under the condition of dynamic change of water level, this paper takes GeoStudio finite element software based on the saturated-unsaturated seepage theory. The numerical simulation of the finite element percolation of the bank slope is carried out. The variation law of the groundwater line under the rise and fall of the bank slope is analyzed, and the groundwater level line at the foundation pit of the building is obtained under the water level change condition. The relationship between the change from the slope to the horizontal distance of the edge of the foundation pit. Which provides a reliable basis for the anti-floating water level of the foundation pit on the bank slope. The calculation results can be used as an important reference data for the anti-floating design of the project, and the anti-floating stability analysis of the foundation pit is instructed.
