基于数值分析的临近地铁的深基坑优化设计

Optimal design of deep foundation pit adjacent to subway station based on numerical analysis

在临近地铁且周边环境复杂的情况下,某深基坑利用三维数值模拟分析软件,对深基坑开挖工况进行模拟。通过模拟明确基坑开挖过程中支护体系的受力及位移情况,并根据分析结果进行优化设计,利用地铁车站已有地下连续墙。经施工监测表明,该方案既满足安全要求,又节约造价。

When environment near the subway is surrounded by a complex structure, three -dimensional numerical simulatiun software is used for a deep foundation pit, which simulated the condition of deep excavation, clear the stress and displacement of the excavation supporting system and optimize the design according to the analysis results, by using the existing underground continuous wall in subway station. The construction monitoring shows that and this solution meets the safety requirements, but also save the cost.
