摘 要:
本文结合武汉市“新世界中心”特大型深基坑喷锚网支护工程实例，应用基于三维快速拉格朗日元法的计算软件FLAC^3D建立喷锚支护结构变形的三维模型，通过对模拟变形与现场实测结果的比较分析，得出喷锚网支护结构侧向位移、竖向位移、沿基坑长（宽）方向上位移的相关研究结论和规律，并验证了三维快速拉格朗日元法应用于基坑喷锚网支护结构变形研究方面的合理性及其优势，丰富并完善了喷锚网支护结构变形的预测理论，其结论对同类工程的研究、设计、施工有重要的参考价值。[著者文摘]

Abstract:
Linking with the real project example-the project of the ＂New World Center＂ in Wuhan and applying the function of FLAC^3D software which is based on the three-dimensional Fast Lagrangian Analysis of Continua, the paper establishes the three-dimensional model. According to the comparation and analysis between the result of simulation transmogrification and that of real survey result in build site, the paper gets the sum-up of research conclusion and rule in lateral displacement, the perpendicular displacement and the construction process of the Shotcret-bolting, and validates the rationality and advantage of applying the three-dimensional Fast Lagrangian Analysis of Continua in the research of foundation pits Shotcret-bolting structure transmogrification. This also has broadened and perfected its forecast theory. The conclusion that we have reached provides an important reference value to the research, design and construction of the kind projects.[著者文摘]
