1.前言 在粘土地基上修建构筑物,有一个土工学上的问题,就是根据构成地基的粘性土种类和荷载条件,用二次压密来显著地表示出来,虽然一般对有机质土一类的软弱粘性土早已有所认识,特别是它的可以看到的倾向,可是,有关构筑物沉降的计算例子似乎不多。最大的原因可能是关于二次压密的室内实验和现场地基之间的相似规律还没有建立。
1. Introduction There is a geotechnical problem in the repair of buildings and structures on clay foundations. It is based on the types of cohesive soils and loading conditions that make up the foundations. It is expressed in terms of secondary compaction, although it is generally a weakness of organic soils. Cohesive soils have long been known, especially its tendency to be seen, but there are few examples of calculations of settlement of related structures. The biggest reason may be that the similarity between the laboratory experiment of secondary compaction and the site foundation has not been established yet.
