| 摘 要： | 喷锚网作为一种新型的基坑支护技术已在基坑施工中大量采用。文中运用快速拉格朗日法对其作了分析研究，基于强度折减法对喷锚网支护下的基坑稳定性作了数值计算，并与传统极限平衡法计算进行比较，得到了较一致的结果，表明该技术在保证基坑稳定性方面具有明显的优越性。

| Abstract: | Shotcrete rockbolt mesh as a new type foundation pit supporting technology has been largely applied in foundation pit construction.This paper studies it with Lagrange method and carries out numerical calculation of foundation pit stability under shotcrete bolting based on strength reduction method,which is in conformance with the result of traditional ultimate equilibrium calculation through comparison.It is indicated that shotcrete bolting technology has obvious advantages in assurance of foundation pit stability. |
