汉口火车站进站厅深基坑支护设计及监测成果分析
摘要:基坑地层性质差,上部为深厚层淤泥质粉质黏土,下部为粉砂,周边建筑环境复杂。根据地层及周边环境,制定了钻孔灌注桩+钢支撑+高压旋喷桩的支护方案。按规范要求进行基坑监测,对基坑开挖起到重要指导作用。整理分析监测成果,并与理论计算值进行对比,可见本基坑支护设计合理,可供其他基坑设计和监测参考。
Abstract:The formation property of the foundation pit was poor.The upper was mucky silty clay and the lower was silt.The surrounding architectural environment was complex.According to formation and the surrounding environment, support scheme of bored piles, steel supports and high pressure jet grouting piles was made.Monitoring based on standard played an important role in guiding excavation.Monitoring results which were analyzed and compared with calculated value showed that support design of the foundation pit was reasonable.The results provided reference for other foundation pit design and monitoring.
