摘要
基于隧道浅埋暗挖段软土深基坑围护结构特征,提出深基坑开挖支护优化方案,进行数值模拟,对比分析基坑支护优化前后钢支撑轴力和桩身侧向变形,结果表明优化方案切实可行。
Based on the features of soft soil deep pit space enclosing structure in shallow buried and subsurface excavation sections of a tunnel, this paper proposes an optimal scheme for deep pit excavation support, simulates numerical values and compares and analyzes steel support axial forces and lateral deformation of piles before and after optimization of pit support. The result shows the optimized scheme is feasible and practical.
