1、本科毕业设计说明书天津奈伦国贸大厦深基坑支护工程变形监测方案设计及相关监测问题探讨DeepExcavationSupportDeformationMonitoringSchemeDesignforTianjinNairnInternationalTradeBuildingandDiscussedtheProblemsrelatedtotheMonitoring摘要随高层/超高层建（构）筑物、地铁工程、大型管道工程等的出现，工程基坑的开挖深度不断加深、规模也愈来愈大，致使基坑安全问题成为我国工程建设事业当中最值得重视的

2、方面之一。为保证在整个基坑工程期所有环境设施的稳定性与安全性，必须在对基坑工程制定详细的监测方案后，进行严格有效的变形监测。本文容共分为四章进行阐述，前两章是作为对后文的铺垫，主要是对基坑变形监测的知识要点进行一定概括简述。第三章为本文重点，以位于天津塘沽响螺湾商务区中南部的奈伦国贸大厦深基坑支护工程为实例，对其制定完整具体的基坑变形监测方案设计，设计监测项目为基坑围护结构及其周围、地下环境设施，以达到及时向设计、施工、建设、监理等单位反馈监测结果，实施信息化施工的目的。介于目前基坑设计理论还不够全面，再加上现有工程

3、的基坑周边及地下状况的复杂多变，虽然基坑变形监测技术随科技进步已向着自动化方向不断发展，但仍不可避免的存在很多问题，本文最后章节即是对此进行叙述探讨，以达到被社会各界更为广泛关注并重视的目的。关键词：深基坑；变形监测；开挖支护；问题ABSTRACTWithmanycountlesshigh-rise,super-tallstructuresandbuildingsincontent,thesubwayengineering,largepipelineengineeringarisingatthehistoricmom
