The invention relates to the field of deep well construction operation, in particular to the field of construction operation of a deep well with a high slenderness ratio, and more particularly relates to an inclination monitoring system and an inclination correction system and method for deep well construction. Shape deformation, overall perpendicularity, displacement of the central axis of the deep well and deviation and trend of the bottom of the deep well of the deep well are obtained through comprehensive data of the upper portion, the lower portion and the well, real-time monitoring of the posture of the deep well is achieved on the basis of the data, and dynamic deviation correction is further achieved through posture adjustment measures of the upper portion and/or the lower portion. And the posture stability in the deep well tunneling process is guaranteed. 本发明涉及深井施工作业领域，特别是涉及高细长比深井的施工作业领域，更为具体的说是涉及用于深井施工的倾斜度监测系统及倾斜度校正系统和方法，通过上部、下部及井筒自身的综合数据获得深井井筒的形状形变、整体的垂直度、深井中心轴线的位移、深井底部的偏位及走向，并以这些数据为依据，实现对深井姿态的实时监控
