In geotechnical engineering, construction in miscellaneous soil-filling areas has been a key and difficult problem.

在岩土工程中，杂填土区的施工历来是施工项目中的重点和难点部分。

The model stratums mainly included miscellaneous filling soil surface, interaction stratum of silty clay, silt and fine sand and pebble round gravel at the bottom of station tunnel.

模型介质材料分别模拟地表杂填土层，粉质黏土、粉土、粉细砂互层和车站隧道底部的卵石圆砾层；

In-situ testing study on the mechanical behavior of soil nailing and the displacement characteristics of miscellaneous fill slope is carried out. A number of significant conclusions are proposed.

对杂填土内土钉的受力特点及边坡的位移特性进行了现场试验研究，得出了若干有意义的结果和结论。
