摘要
土钉支护对基坑变形的调节和控制能力较差,不适于对变形控制要求较严格的深基坑工程。采用微型桩+预应力锚索配合土钉支护的新型复合土钉支护方案,经有限元计算对复合土钉和一般土钉的两种方案变形曲线进行对比、分析。结果表明,对基坑变形要求严格时,该复合土钉支护方案能有效地控制基坑变形。
The deformation of deep excavation supported by soil nail is unsuitable to strict requirement of deep excavation. The new method of soil nailing with micro-pile and pre-stressed anchor wire was used to control the deformation of deep excavation. Compared the curves of deformation in composite soil with those in common soil, finite element method, the method is able to control the deformation effectively.
