跨湖桥独木舟遗址区地下水渗流场模拟研究

独木舟遗址位于浙江省萧山区，是浙江省迄今为止发现最早的新石器时代文化遗存。现场踏勘发现，破坏遗址原址保护主要环境地质病害是水的问题。通过对该遗址区水文地质条件的分析，建立了遗址区水文地质概念模型和数学模型；运用地下水数值模拟软件Modflow模拟遗址区原始地下水分布；将模拟区地形图与模型模拟结果进行比较，发现它们具极大的相似性，这说明模拟的结果是符合实际情况的。

Simulation Study on Seepage Field of Groundwater in the Striding Lake Bridge Site Area

The Canoe Site lies in Xiaoshan City of Zhejiang Province and it is the earliest cultural remains site of the New Stone Age in the province. The authors had investigation on the spot and found that the main environ-geology disease that damages the tomb preservation is caused by water. By analyzing the hydrogeologic conditions of the site, the authors built the hydrogeology conception model and the mathematical model, and utilized the numerical simulation software Visual Modflow to simulate the distribution of groundwater. Then the authors compared the geographic map of the site with the result of the simulation, and found they have much comparability. That shows the simulation is in accordance with the facts.
