The invention provides a shield tunnel site water and soil pressure monitoring method used under complex stratum conditions, and belongs to the technical field of underground shield construction. According to the invention, the embedded base and the outlet box are embedded in advance, and the test instrument is installed at the reserved point of the embedded base after the duct piece is cast and formed, so that the method can be well suitable for the water and soil pressure test method under the construction condition, the survival rate of the instrument can be ensured to a great extent, and accurate monitoring data can be obtained; the influence of direct pre-burying of a testing instrument on the casting quality of the duct piece can be reduced, and meanwhile the risk that the testing instrument is damaged in the casting process is reduced. 本发明提供了一种用于复杂地层条件下的盾构隧道现场水土压力监测方法，属于地下盾构施工技术领域。本发明提前预埋预埋底座和出线盒，待管片浇筑成型后，在预埋底座的预留点位安装测试仪器，能较好适用该施工条件下的水土压力测试方法，能够较大程度保证仪器的存活率并获取较为精确的监测数据，能够减少直接预埋测试仪器对管片浇筑质量的影响，同时降低在浇筑过程中
