摘要
某矿井生命线工程———副井井口房工程 ,因基础位于冻结土上 ,由于冻结土的融陷产生不均匀沉降而发生了严重的结构裂缝。论文从工程地质、设计选型、施工质量等几个方面分析了结构裂缝产生原因 ,详细介绍了沉降观测、裂缝处理的方法和过程 。
Surface structures,which closely surround the mouth of Qinan Coalmine's subsidiary shaft,are a lifeline project.Their foundation lies well upon frozen earth.Because of uneven sinking of the frozen earth,fissures have occurred in the above structures.This paper analyzes its causes from several aspects,such as engineering geology,design and model selection,construction quality,etc.Then,it not only describes the surveying procedures for those fissures and relevant countermeasures,but brings about some suggestions for similar construction projects in the future.
