One kind of deep foundation settlement monitoring methods

The invention relates to a method for monitoring the deep settlement of a foundation, which is characterized in that: a liquid level static pressure monitoring method is adopted; in the liquid level static pressure monitoring method, a container provided with a pressure sensor and a secondary instrument is adopted, taken as a pressure measuring reference container and fixed on the ground which isnot influenced by the foundation settlement; the height of a pressure sensing surface of the pressure sensor is greater than that of any one embedded settlement instrument; the embedded settlement instrument consists of a shell, a three-way joint, a pressure sensor, a secondary instrument circuit and a serial bus circuit and is electrically connected with other embedded settlement instruments anda ground measurement and control system through an electric serial bus; and the measurement and control system records a pressure value of each detection point, converts the pressure value into a foundation settlement value, and performs curve fitting to obtain a foundation section settlement outline.
