Friction resistance adjustable open caisson and resistance control method

The invention provides a frictional resistance adjustable open caisson, and belongs to the technical field of building construction. The frictional resistance adjustable open caisson comprises an open caisson main body and a plurality of groups of frictional resistance adjusting assemblies, wherein each group of frictional resistance adjusting assembly comprises a connecting piece connected to the open caisson main body, a supporting piece connected to the connecting piece and used for making contact with a stratum wall surface, and a stratum cutting piece arranged on the connecting piece or/and the supporting piece, wherein the stratum cutting pieces are used for breaking a stratum for preventing the sinking of the open caisson main body, and a controller is electrically connected to the frictional resistance adjusting assemblies and used for collecting data when the open caisson main body sinks and controlling the frictional resistance adjusting assemblies to generate corresponding movement.
