湿陷性黄土地基处理的目的主要是,通过消除黄土的湿陷性,以提高地基的承载力。常用的地基处理方法有以下几种。对这些处理方法应当因地制宜,通过技术经济综合比较后合理采用。一、土或灰土垫层土或灰土垫层一般适用于消除1～3 m厚土层的湿陷性。试验研究表明:在附加压力作用下,土层浸水后的最大湿陷变形发生
The main purpose of collapsible loess foundation treatment is to improve the bearing capacity of foundation by eliminating the collapsibility of loess. Commonly used foundation treatment methods are the following. These treatment methods should be adapted to local conditions, through a comprehensive comparison of technology and economy after a reasonable use. First, the soil or lime soil cushion or lime soil cushion is generally applicable to eliminate 1 ~ 3 m thick soil collapsibility. Experimental results show that under the action of additional pressure, the maximum collapse deformation occurs after soaking
