强夯振动影响范围和建筑安全监测评价

Influence scope of dynamic compaction vibration and construction safety monitoring evaluation

在南水北调中线漳古段工程中,湿陷性黄土分布广泛,利用强夯法加固地基,消除黄土湿陷性,达到压实加固目的。但由于受环境条件限制,针对强夯施工带来的振动安全问题,必须进行监测评价,以维护工程质量和环境安全稳定。本文根据该工程提出安全监测标准和试验研究成果,并对施工环境中的建(构)筑物进行了安全监测评价。

Collapsible loess is widely distributed in South-to-North Water Diversion Project mid-line Zhanggu section work.Dynamic compaction method is utilized to reinforce foundation and eliminate collapsibility of loess for compaction and reinforcement. However,vibration safety problem in dynamic compaction construction must be monitored and evaluated due to limits of environmental conditions,thereby maintaining project quality as well as environment safety and stability. In the paper,safety detection standards and experiment research results are proposed according to the project. Buildings（ structures） in construction environment has undergone safety monitoring and evaluation.
