The invention discloses a dynamic adjustment method and system for unbalanced loads on the two sides in continuous beam cantilever construction. The method comprises the steps that an unbalanced load difference value f (LD, RD) is determined according to beam left end weighing data LD and beam right end weighting data RD, a machine halts when a reversing valve is subjected to two-way jam, otherwise, comparison is conducted with preset unbalanced load difference value threshold value+TV according to the unbalanced load difference value f(LD, RD), a pump truck is controlled to continue to convey concrete according to the comparison result or the pump truck is controlled to stop pumping first and then control the reversing valve to be subjected to reversing according to the pumping action state of the pump truck and the valve location information of the reversing valve, after the reversing valve is subjected to reversing, the reversing state is inspected first, and then a pumping instruction is sent in a delayed
