盾构下穿古旧平房动态安全评价与系统研发

DEVELOPMENT OF DYNAMIC SAFETY EVALUATION SYSTEM FOR THE STABILITY OF OLD BUNGALOW UNDER THE WORK OF SHIELD MACHINE

为快速准确判断盾构施工对古旧平房安全稳定性的影响情况,利用物联网技术实现监测数据采集与传输。结合层次分析法和模糊综合评价法建立盾构下穿古旧平房的综合评价模型,并考虑评价指标的动态性确定古旧平房安全性等级。采用Microsoft Visual C#.Net编程语言和SQL Server 2008数据库技术研发了一套盾构下穿古旧平房安全评价系统。此系统应用于国内某在建地铁项目,能够有效指导施工,规避可能存在的风险,保证盾构下穿古旧平房施工安全可靠。

In order to rapidly and accurately evaluate the effect of the construction of shield machine on the old bungalow, the internet of things was used to achieve the collection and transmission of the mo- nitor information. Based on the analytic hierarchy process and fuzzy comprehensive evaluation methods, a comprehensive evaluation model about the old bungalow under the construction of shield machine was established, and this model took the dynamic of the evaluation index into account to determine the safety level of old bungalow. The safety evaluation system for the stability of old bungalow under the work of shield machine was developed by using Microsoft Visual C#. Net and SQL Server 2008 database technolo- gy. Moreover, this system was used in subway project under construction in China, guiding the construc- tion, avoiding the risk, ensuring the safety and reliability of old bungalow when shield machine worked.
