The invention discloses a foundation 
ditch monitoring method in 
construction engineering. The foundation 
ditch monitoring method comprises the following steps that relative information of site surveyand collection is processed and input in the 
construction engineering foundation 
ditch monitoring system, and a foundation ditch monitoring scheme is developed based on monitoring requirements, specifications and regulations; measuring points are arranged, a soil and 
water pressure monitoring element, a sensor, an 
inclinometer pipe and a layered settlement 
pipe are embedded to monitor physical parameters of exterior-protected construction deformation and internal force, 
terrain movement and ground surface 
subsidence; early warning value degree is preset, the early warning value degree comprises deformation or internal 
force magnitude and change rate thereof; project data automatically collected and monitored by an on-site terminal are collected and uploaded automatically, analysis and 
processing are carried out by a 
central processing unit based on the uploaded data, and curve diagrams and monitoring reports are formed; the curve diagrams and monitoring reports are stored in a storagemodule and history memory is formed; and the curve diagrams and monitoring reports are printed by a printing module. Real time monitoring is achieved, and the state of the foundation ditch in the 
construction engineering can be reflected accurately and timely.
