摘要
下沉广场式建筑因与土层直接接触,存在向上渗流涌水的可能。该文以北京某下沉广场为例,通过分析场区水文地质条件,建立适用的水文地质概念模型并确立地下水流定解数学模型,使用数值模拟软件seep/w建立模拟模型,利用该模型进行了在有地下连续墙侧向隔水作用,以及下沉广场不进行地基防渗处理情况下的涌水量预测。
The sunken square doesn＇ t set waterproof soleplate as a role, but the groundwater may go up and exceed the ground of sunken square, we must take some measures to predict the discharge of sunken square. Taking the certain sunken square in Beijing as example, through analysis of the hydro-geological conditions, the hydro-geological concept model is established to determine defining solution mathematical model of ground- water. The seep/w numerical simulation software is used to create the numerical model. Under the action of the lateral waterproofer of the underground diaphragm wall, the model predicts the discharge without anti-seepage treatment of sunken square.
