摘要:
在测定某市土壤物理参数和分析降雨资料的基础上，以建筑物周围下凹式绿地为研究对象，利用HYDRUS-2D软件模拟分析下凹式绿地的渗水过程，探讨了厚度范围在30~60 cm、深度与建筑物基础相同的垂直土壤夹砂层在下凹式绿地中的侧向阻渗作用。结果表明,设置土壤夹砂层一侧，湿润锋运移距离平均减少59.1%，在夹砂层后的观测点含水量减少45.5%，可以使建筑物基础周围的黄土规避湿陷性危害。
Abstract:
Based on determination of soil physical parameters and analysis of rainfall data in a city, HYDRUS-2D software was applied to simulate the water seepage process of sunken lawns around the building, and the lateral impermeability of the vertical soil sand layer with the thickness of 30-60 cm and the same depth as the building foundation in the sunken lawn was discussed. On the side of the soil sand layer, the wetting front migration distance was reduced by an average of 59.1%, the water content of the observation point after the sand layer was reduced by 45.5%, which could avoid the collapsible harm of the loess around the foundation of the building.
