摘　　要：文章通过对综合深井前兆仪器与地面台站前兆仪器产出的地磁、水位、水温、钻孔应变、钻孔倾斜资料进行日变曲线、长期变化曲线、内在质量等对比分析,认为综合深井前兆观测作为一种新的观测系统,可节约空间,利于实施;观测数据稳定、可靠,能避免来自表层的干扰,但对于轨道交通等直流干扰仍无法避免,主要缺点是不便于维修且费用较高。By comparing and analyzing the diurnal curve,long-term change curve and internal quality of precursory instruments which output geomagnetism,water level,water temperature,borehole strain and borehole tilt data in comprehensive deep well and at the ground station,the comprehensive deep well precursor observation is considered as a new observation system,which saves space and is beneficial to the implementation.The data of the new observation system are stable and reliable.Besides the direct current interference such as rail traffic,the interferences from the surface can be avoided.The main disadvantage is that the maintenance is inconvenient and expensive.
