针对我国工程界对黄土湿陷性认识不足的问题,以西安财经学院曲江校区场址为依托,对该场址的黄土进行现场浸水试验研究。采用一直径为30m,深0.5m的试坑,从试坑中心向外辐射3条观测线,观测线上布置观测点,观测各点处浸水引起的沉降。结论认为,场地浸水湿陷分为初始反弹阶段、平缓阶段、陡升阶段、回弹阶段。 Aiming at the lack of understanding about the collapsibility of loess in our country’s engineering field, this paper, based on the site of Qujiang Campus of Xi’an University of Finance and Economics, conducts a field immersion test on the loess site. A test pit with a diameter of 30m and a depth of 0.5m was used to radiate three observation lines from the center of the test pit. Observation points were arranged on the observation line and the subsidence caused by immersion at each point was observed. The conclusion is that the wet soaking of the site is divided into the initial rebound stage, the gentle stage, the steep rise stage and the rebound stage.
