Abstract: A system and method for monitoring an earth pressure and displacement of a miniature steel pipe pile body. Sensor installation holes are drilled at predetermined positions outside the steel pipe pile body and sensor metal protective shell with a thickness slightly lower than that of the XY-TY02A resistance-type miniature earth pressure gauge is welded on the steel pipe pile body. The XY-TY02A resistance-type miniature earth pressure gauges are stuck on the steel pipe pile body. The transmission line of the XY-TY02A resistance-type miniature earth pressure gauges passes through the sensor installation holes and are connected to data acquisition system. The reflective sheet base is welded at the preset position of the miniature steel pipe pile and the reflective sheet is attached to the reflective sheet base to realize displacement monitoring.
