基于GMS模型的保利未来城抗浮设防水位研究

Research on Water Level for Prevention of Up-floating of Poly Future City Base on GMS Model

建设项目抗浮设防水位包括地下水位预测和建筑基底水压力的计算两方面内容。随着水资源评价和工程建设的发展,对抗浮设防水位不再仅仅满足于经验值,有必要对如何科学有效地进行地下水位预测和计算建筑基底水压力展开研究。论文采用GMS软件中的MODFLOW模块建立地下水水流模型,并考虑各种不利因素以百年一遇的降水为设计方案对北京保利未来城地下水位进行了预测。最后根据地下水位预测结果以及水位与未来城结构底板的关系计算出基底水压力,为建设项目的设计与施工提供了科学的依据。

Water level for prevention of up-floating of construction project include ground-water level forecast and construction of basal water pressure calculation in two aspects. With the water resources assessment and engineering construction to resist the floating water level is no longer just meet the experience, it is necessary to study how to effectively carry out the prediction of groundwater level and calculate the base water pressure of the building. The groundwater flow model using MODFLOW module in GMS software, consider various unfavorable factors to the hundred years of precipitation for the design scheme to predict the water level in Beijing Poly future city. Finally, according to the prediction results of groundwater level and the relationship between the water level and the future city, the base water pressure is calculated, which provides a scientific basis for the design and construction of the construction project.
