| 摘 要： | 湿陷性黄土地基的处理常采用破坏原状土结构的技术措施,从而不能充分发挥天然地基的承载力。当处理深度较大时,其施工难度较大,费用较高。结合深厚湿陷性黄土地基具有地势高、地下水位深、含水量低的条件,提出了浅层阻水、浅层排水、浅层防水、围封截水和竖井深层导水的综合整治新技术。进而,通过降雨入渗计算分析评价了综合整治新技术的处理效果。这种处理技术具有防止水分侵入地基、加强自由水引排和充分发挥天然土体承载力的特点,是处理深厚湿陷性黄土地基的一种新途径。

| Abstract: | The treatment measures for loess foundations often destroy the structure of in situ loess,and thus cannot adequately bring out the natural carrying capacity of loess.If the loess is deep,these measures would be difficult and expansive.Considering the characteristics of wet-collapsible loess and the real conditions of deep loess,such as high topography,deep water table and low water content,a set of novel integrative treatment technology that includes impedance,drainage,interception,truncation and infiltration has been put forward.This technology can prevent water seepage,promote free water drainage and enhance the carrying capacity of loess.The effect of the new comprehensive treatment method is analyzed by a rainfall seep calculation. |
