摘要
Abstract
Combined with the engineering practice of the block No.11 Xihu Avenue in the south of Yuanfu Lane historical section in Hangzhou area,the study on the effect of adjacent tunnel induced by deep foundation pit support is carried out.Due to the complex and sensitive sur-rounding environment of the project,the north side is the operation of the subway tunnel.In order to keep safety of the existing tunnel,the de-sign scheme of foundation pit support of the project is introduced in detail,and the finite element method is adopted to carry on the preliminary study of the underground tunnel.By comparing with the monitoring data,the simulation results are close to the measured data,which further proves the reliability of the finite element model.Then the reasonable suggestions are put forward according to the analysis results,and the rel-evant conclusions can provide experience reference and practical guidance for the design and construction of foundation pit engineering in the highly sensitive environment of silty soil area.关键词
