<P>PROBLEM TO BE SOLVED: To provide a method and an apparatus for remotely and automatically operating soil bearing test equipment, which enable a remote automatic operation from ground, until a soil bearing test for being performed in a high-pressure working chamber for a pneumatic caisson method is completed by changing a load actually applied to the ground, making the load agree with an applied design load and measuring the amount of the displacement of the ground, from the installation of the soil bearing test equipment on a testing site. Ž<P>SOLUTION: A control device is provided in the remote automatic operation apparatus on the atmospheric-pressure side of a pneumatic caisson; an output command value for operating a jack for the applied load for a loading test of the soil bearing test equipment on the side of the high-pressure working chamber is transmitted to a pressure control device from an automatic control device; and the actually-applied load is automatically adjusted in real time so as to agree with the applied design load.
