摘　　要：结合萧山北干山永久路新开隧道下穿人防工程监测项目,研究了公路隧道在近接既有人防工程施工过程中的监测方法,从而建立了一套较为健全、完备的监测方法.主要涉及监测仪器的选取、监测指标值的选取、监测频率的确定及测点的布设等.根据本监测方法选取了监测结果中的底板位移及围岩压力进行数据处理,验证了本监测方法的可行性与合理性.Accounting for the excavating effects of the Yongjiu road tunnel in the Beigan Moufitain on adjacent existing civil air defense works, the method of monitoring the works during the highway tunnel construction using drill-blasting method was studied in order to establish a more robust method of monitoring. The method is mainly concerned with the selection of monitoring equipment, the warning value, the frequency of monitoring, the positioning of monitoring points, etc. The surrounding rock deformation and pressure change of roadway floors were analyzed to show the feasibility and reasonableness of the monitoring method.
