乌鲁木齐地铁一号线无水砂石回填区盾构施工分析与控制

Analysis and Control of Shield Construction in Anhydrous Sand Backfill Area of Urumqi Metro Line 1

摘要: 盾构施工会造成土体变形，给施工区域周边建筑物以及施工作业产生不利影响。在松散的无水砂卵石回填区进行盾构施工，这种安全隐患更大，就需要提前对施工作业中可能存在的风险做出一些调整和优化。本文首先将对无水砂卵石回填区地铁盾构施工进行总体的风险分析，然后以乌鲁木齐地铁一号线无水砂卵石回填区为背景，进行盾构施工风险分析并提出风险控制措施和实际工程效果。

Abstract: Shield construction will cause soil deformation and adversely affect the surrounding buildings and construction operations. When shield construction is carried out in loose anhydrous gravel backfill area, this kind of hidden danger is bigger, so it is necessary to make some adjustment and optimization to the possible risks in construction operation in advance. In this paper, the overall risk analysis of shield construction in anhydrous gravel backfilling area is carried out at first, and then the risk analysis of shield construction in anhydrous gravel backfilling area of Urumqi Metro Line 1 is carried out and the risk control measures and actual engineering effects are proposed.
