基于真空预压的市政道路软基沉降监测与安全评估

Monitoring and Safety Assessment of Soft Foundation Settlement of Municipal Roads Based on Vacuum Preloading

摘要:

真空预压法是市政工程中加固软土地基的常用工艺,能够有效提升软土地基承载力、减小工后沉降,保障市政道路的长期运营稳定性。文章结合天津市政道路工程实践,针对真空预压处理软土地基的沉降监测方案与实施过程展开分析,结合现场监测数据总结沉降发展演化规律,从累计沉降量、沉降速率、差异沉降多个维度完成软基加固后的安全性与加固效果评估,验证真空预压法在市政道路软基处理中的应用成效,为同类工程的沉降监测与安全评估工作提供参考。

Abstract:

Vacuum preloading method is a commonly used technique for reinforcing soft soil foundation in municipal engineering, which can effectively improve the bearing capacity of soft soil foundation, reduce post construction settlement, and ensure the long-term operational stability of municipal roads. The article combines the practice of Tianjin municipal road engineering to analyze the settlement monitoring plan and implementation process of vacuum preloading treatment for soft soil foundation. Based on on-site monitoring data, the development and evolution law of settlement is summarized. The safety and reinforcement effect evaluation of soft soil foundation reinforcement are completed from multiple dimensions such as cumulative settlement, settlement rate, and differential settlement. The application effect of vacuum preloading method in municipal road soft soil foundation treatment is verified, providing reference for settlement monitoring and safety evaluation of similar projects.
