非剪胀性软土隧道的土体变的预测

Predicting Deformation during Excavation of Clay Tunnel

提出一种简单的分析方法 ,分析非翦胀性地层变菜性状 ,并将结果与试验资料对比分析 ,预测圆形隧道周边变形和地表沉降的分布形式及规律 .

When a shallow day tunnd is excavated in soft ground,the ground above and on the both sides of the tunnel deforms towards the opening.A simple analysis method is put forward in this paper. It can forecast the deformation around tunnel and the settlement of the earth's surface.
