1. An earth pressure and displacement monitoring system of a steel pipe pile body, comprising:
resistance-type earth pressure gauges,
sensor metal protective shells,
a resistance test strain gauge,
a data storage device,
reflective sheets,
supporting plates, and
reflective sheet base rebar ends; wherein
sensor installation holes are arranged on the steel pipe pile body; the sensor metal protective shells are arranged at positions where the resistance-type earth pressure gauges being installed, resistance-type earth pressure gauges are connected to the resistance test strain gauge through a transmission line, and the resistance test strain gauge is connected to the data storage device;
a top beam is installed on a top of the steel pipe pile body, and waist beams are evenly distributed on an outer surface of the steel pipe pile body; a protruding end of each reflective sheet base rebar end is provided with a supporting plate, and each reflective sheet is installed on the supporting plate.
