| 摘 要： | 复合土钉墙中,突入基坑的阳角较基坑其它区域稳定性较低,风险也更高,由于阳角部位受力较复杂,一般分析中往往进行简化,将基坑中部剖面的分析结果应用于阳角部位,偏于不安全.针对这一情况,对复合土钉墙的阳角进行三维有限元分析,研究了与阳角不同距离的土钉受力状况,结果表明受力最大的土钉出现在长边邻近阳角的区域,该处较阳角的转折点更不安全,为最危险处.

| Abstract: | Stability of convex location is the lowest in composite soil nailing wall.Due to the complexity of pull of soil nail at convex location,usually the convex location was simplified as central section of composite soil nailing wall for analysis on pull of soil nail,and the analysis result was unsafe.In this paper the behavior of pulls of soil nails at convex location was analysed accordingly by three-dimension elasto-plastic FEM.The results show that the soil nails with maximum pull are at longer side and near convex location,and corresponding area is the most dangerous one in composite soil nailing wall. |
