中风化岩层地质边坡高空支护施工技术研究

Study on Construction Technology of High Altitude Support for Geological Slope in Moderately Weathered Rock Stratum

近年来,我国部分地区建筑工程施工质量安全事故频发,造成施工作业人员群死群伤。造成安全事故的原因,源于工程施工期间对实体质量、施工安全管理的忽视,对“危大工程”施工危险源控制、排除重视程度的弱化。对于城市内复杂地质及周边环境下的超深基坑支护工程,通过对基坑中所潜在的重大危险源进行分析,制订针对性强、精确性高、工序合理的治理措施,以期高质量完成高空支护施工。

In recent years,construction quality and safety accidents occur frequently in some areas of our country,resulting in the death of construction workers.The causes of these accidents are due to the neglect of the quality and safety management during the construction of the project,and the weakening of the attention to the control and elimination of the dangerous sources in the construction of the"dangerous and big project".For the support engineering of ultra-deep Foundation pit in the city with complex geology and surrounding environment,through the analysis of the potential major hazard sources in the foundation pit,the control measures with strong pertinence,high accuracy and reasonable working procedure are worked out,to complete the high-altitude support construction with high quality.
