摘要:
为了寻求适合黄土地区公路路基湿陷性评价的方法,找到符合公路工况的实际水分入渗规律,通过现场 人工降雨试验,观测了湿陷性黄土路基在百年一遇降雨强度下的入渗以及饱和深度,并结合有限元数值模拟,分 析了湿陷性黄土降雨入渗的规律。结果表明:在降雨条件下湿陷性黄土路基入渗的影响深度小于2.7m,饱和 深度为20cm。该结果可为黄土地区路基处理设计中的黄土湿陷性评价、施工提供依据。
Abstract:
To find an effective method for evaluating the collapsibility of loess subgrade, site tests on the saturated depth and infiltration of subgrade loess under artificial rainfall circumstance were done. The infiltration and saturated depth werer observed on site, the process of infiltration also was simulated. It is found that the depth of infiltration is not more than 2.7 m, and the saturated depth of loess is just 20 cm. This conclusion can provide a reference for designers and constructers.
