Analysis of Bearing Capacity and Settlement Trend of Foundation Soil at Different Depths of High-rise Buildings
To ensure the reasonable design and stability evaluation of high-rise buildings,this article first combines the geological conditions of the project area to conduct an analysis of the bearing capacity of the foundation soil,and conducts research on the trend of building settlement through settlement monitoring and prediction.The analysis results show that with the change of depth,there are significant differences in the distribution thickness and bearing capacity of different strata.Considering the excavation depth of the foundation pit,the layer thickness of the pebble layer is 5.5 m,and with good uniformity and high bearing capacity,its burial depth also meets the design requirements.Therefore,it is reasonable to use it as the foundation bearing layer.Through monitoring,the settlement deformation values of 9 monitoring points range from 26.29 to 50.27 mm,which is within the deformation control value range.Through deformation prediction,the building settlement shows a small rate of increase,with the predicted settlement values ranging from 41.98 to 51.03mm.The predicted settlement values are also within the control value range,indicating that the control effect of building settlement deformation has always been excellent,providing certain theoret-ical support for the design and stability evaluation of high-rise buildings.
