基于数值模拟技术预测某场地抗浮设防水位的研究

Study on Prediction of Anti Floating Water Level of a Site Based on Numerical Simulation Technology

结合邢台市某建设项目,采用数值模拟技术对场地抗浮设防水位进行模拟分析与预测。根据场地工程地质条件建立一个补给、径流、排泄的水文模型,选取一个水文年对该模型进行模拟,将模拟结果与实测水位值进行对比分析,通过调整相关参数使误差在合理范围内。进而考虑邻近地表水系对该项目场地地下水位的影响并进行模拟预测,提出合理的抗浮设防水位。为类似项目抗浮设防水位的确定提供一定的参考。

Combined with a construction project in Xingtai City,numerical simulation technology is used to simulate,analyze and predict the anti floating water level of the site.According to the engineering geological conditions of the site,a hydrological model of supply,runoff and discharge is established,and a hydrological year is selected to simulate the model.The simulation results are compared with the measured water level values,and the error is within a reasonable range by adjusting the relevant parameters.Then,the influence of adjacent surface water system on the groundwater level of the project site is considered and simulated,and a reasonable anti floating fortification water level is proposed.It provides a reference for the determination of anti floating water level of similar projects.
