摘要
复合土钉支护是近年来在软土地区出现的一种新型基坑围护结构,已得到广泛应用。运用有限元方法分析了土钉长度、土钉间距及水泥土桩嵌固深度等支护参数对复合土钉支护变形的影响,并用正交试验方法分析了各影响因素对变形的敏感度,为复合土钉支护的设计和施工提出一些建议。
Composite soil nailing is a new support structure which developed at soft soil and is widely used. The influencing factors on deformation of composite soil nailing were discussed with the finite element method, such as the length, slope angle of soil nail and the build - in length of soil - cement pile and so On. The sensitivity of the factors which analyzed above was discussed with the orthogonal test. The result offered some useful advice for the design and construct of composite soil nailing.
