摘　　要：近年来,在多方面因素的影响下,使得我国综合国力得到了显著的提升,从而为各个领域的发展壮大带来了诸多的机遇。我国国土面积广阔,从而也就造成了各个地区土质结构存在明显差别的情况,很多地区都存在湿陷性黄土土质问题。湿陷性黄土结构整体松散性较强,结构稳定性较差,在这类土质地区进行建筑工程的施工工作,往往会为施工工作带来诸多的困难,如果任何一个环节出现失误都可能会引发危险事故。所以我们需要针对湿陷性黄土地基利用专业的方式方法加以处理,这样才能切实的规避结构坍塌的情况。湿陷性黄土其实质就是土质结构密度较大,整体土体机构稳定性较差,在受到液体的侵蚀之后,往往会在短时间内发生结构下沉的情况。以上不仅是湿陷性黄土所具有的特征,并且也是引发建筑路基结构稳定性的主要隐患,如果不能切实高效的加以解决,那么必然会引发地基折裂、形变或者是结构下沉的情况。为了切实的提升湿陷性黄土地基结构的稳定性,还需要我们针对湿陷性黄土结构进行全面的分析研究,综合各方面实际情况,利用有效的方式方法对其中存在的问题加以切实的解决。In recent years,under the influence of various factors,Chinese comprehensive national strength has been significantly improved,which has brought many opportunities for the development of various fields.China has a vast land area,which results in the obvious difference of soil structure in different regions.Many areas have collapsible loess soil problems.Collapsible loess structure is loose as a whole and its structural stability is poor.In this kind of soil area,the construction work of building engineering often brings many difficulties to the construction work.If any link fails,it may lead to dangerous accidents.Therefore,we need to use professional methods to deal with collapsible loess foundation,so as to effectively avoid structural collapse.The essence of collapsible loess is that the density of soil structure is high and the stability of the whole soil body is poor.After being eroded by liquid,the structure subsidence often occurs in a short time.The above is not only the characteristics of collapsible loess,but also the main hidden danger of structural stability of building subgrade.If it can not be effectively solved,it will inevitably lead to foundation cracking,deformation or structural subsidence.In order to effectively improve the stability of collapsible loess foundation structure,we also need to carry out a comprehensive analysis and Research on collapsible loess structure,synthesize the actual situation in various aspects and use effective methods to solve the existing problems.
