【摘要】 针对基坑上部为黏性土、下部砂土,就土钉支护结构的滑移面的形状问题,采用有限元软件Plais和ANSYS对土钉墙滑移面进行数值模拟,得到上部黏性土中为近似圆弧型,下部砂土中为直线型,其界线点在黏性土和砂土的分界面上,且滑移面不通过趾脚。用该滑移面进行土钉墙支护设计,可节省部分经费,并减轻工人的劳动强度。更多还原

【Abstract】 The fundamental pit is made by clay in upper,and by sand in lower. As for the slip surface of the soil-nail bracing,adopting finite element software Plais and ANSYS for simulation,the authors obtained the clay arc in shape and the sand straight line shaped. The intersect point is lay at medium interface of the two parts,and the slip surface didn’t go through toe. Using the slip surface is economical and intensity-saved for labors to design soil nailing walls.更多还原
