黄土是第四纪地质时期里的特殊沉积物,在天然状态下它具有较高的孔隙率(一般在45～50％以上),但是,由于天然状态的黄土颗粒间具有较强的加固粘聚力,能够承担一定的压力而不至产生很大的变形,因而浸水后发生湿陷。一般建筑物建成后地基是否会浸水和浸水的程度,往往难以予计,所以黄土地基实际湿陷值的确定也就变得很复杂而难以估计,但是,如果能从黄土地基浸水后变形的分布情况和范围以及其与一系列影响因素间的关系加以研究,无论在实际工程中或是为了进一步探讨黄土湿陷性的理论方面,都
Loess is a special sediment in the Quaternary geological period. In the natural state, it has a high porosity (usually 45 to 50%), but due to the strong reinforcement of the natural loess particles Force, able to take a certain pressure without causing great deformation, so that after water soaked collapse. It is often difficult to predict whether the foundation will be submerged or soaked after the completion of a typical building. Therefore, the determination of the actual collapse of the loess foundation becomes complicated and difficult to estimate. However, if the deformation of the loess can be inundated The situation and scope as well as their relationship with a range of influencing factors are studied, both in actual engineering and in order to further explore the theoretical aspects of loess collapsibility.
