摘要
针对某一复杂地层大直径超深输水隧道建设工程,通过对施工过程中结构与土层位移、沉降监测数据进行统计分析,并将分析结果与沉降曲线为偏态分布的估算方法进行对比,揭示施工过程中地下水位变化、地连墙水平位移、地表沉降规律,并分析推断出大直径工作井地连墙水平位移和地表沉降分布不均匀的原因,最后提出减小地连墙水平位移与地表沉降施工控制方法及措施。
Combined with the construction project of a large-diameter deep-buried water-supplying tunnel in a complex formation,statistical analysis is carried out on data results of displacement and settlement monitoring of structure and soil layer during construction,and the analysis results are compared with the estimation method that the settlement curve is skewed distribution,it reveals the law of groundwater level development,horizontal displacement of underground continuous wall and surface settlement during construction.In addition,the reasons for the uneven distribution of the diaphragm wall horizontal displacement and surface settlement of large-diameter working wells are analyzed and deduced,and finally the construction control methods and measures are put forward for reducing the horizontal displacement and surface settlement of the diaphragm wall.
