桥梁基础施工危险源分析及深基坑安全监测技术

Analysis of Bridge Foundation Construction Hazard and Deep Foundation Pit Safety Monitoring Technology

对桥梁施工的风险评估体系和评估方法进行介绍,结合桥梁工程实例,通过获取该工程的风险因素,进行施工风险的估计和评价,并提出施工风险的应对策略,对边坡稳定性、围护桩顶部位移和倾斜变形、地下水位3个指标进行监测,通过分析监测结果得知3个指标均在预警值范围内,从而保证了桥梁施工安全。

This paper introduces the risk assessment system and assessment method of bridge construction. Combined with the bridge engineering example, the construction risk is estimated and evaluated by obtaining the risk factors of the project, and the countermeasures of the construction risk are proposed, and the slope stability, the displacement and inclined deformation of the top of the retaining pile and the groundwater level are monitored. By analyzing the monitoring results, we know that the three indexes are all within the range of warning value, thus ensuring the safety of bridge construction.
