湿陷性黄土约占中国黄土分布面积的60%左右,主要分布于黄河中、下游地区,厚度最大达30m左右。并具有自东向西、自南向北其湿陷性逐渐加剧的规律。对于土层较薄的湿陷性黄土地基处理的方法很多,但建筑物地基处理,基本消除基础已有土层的湿陷性,强夯是其常用方法之一。 Collapsible loess accounts for about 60% of China’s loess area, which is mainly distributed in the middle and lower reaches of the Yellow River with a maximum thickness of about 30m. And from east to west, from south to north its collapsibility gradually increased law. There are many ways to deal with the collapsible loess foundation with thinner soil layers. However, there are many collapsible collapsible layers in the basement of the building for foundation treatment. Dynamic compaction is one of the commonly used methods.
