流砂地层中复合土钉墙的受力及变形性状

Deformation and Mechanical Behavior of Compound Soil-nailed Retaining Wall Used in the Ground with Flow Sand

介绍东方肝胆医院基坑工程采用复合型土钉墙支护的设计、施工,以及对支护边坡的变形性状、土钉受力变形机理、喷层作用所进行的测试和研究,总结与改进了复合型土钉挡墙的设计方法。

The foundation pit lay in the silty and sandy layer in which the flow sand will be easily produced. The underground water retaining proof curtain is formed with the compound soil-nailed wall. The excavating depth is up to 7 meter. The displacement and settlement are satisfied to the deformation standard of I level foundation pit. The deformation,deep layer displacement and the forces of anchor are measured in the field.
