Rotation continuous beam automatic weighing method and system used for horizontal rotation construction

The invention discloses a rotation continuous beam automatic weighing method and system used for horizontal rotation construction. The rotation continuous beam automatic weighing method used for horizontal rotation construction comprises the steps of using a designated starting side as an initial side to start to alternately jack a rotation continuous beam on a single side in a side-changed mannerby using a gradually increased jacking force so as to obtain a jacking force stable value P1; continuing to slowly release pressure of the jack for applying the jacking force till the pressure of thejack is completely released; determining an attitude type of the rotation continuous beam according to displacement data in the releasing process, wherein the first type of attitude is using a reverse side of the starting side as the initial side to start to alternately jack the rotation continuous beam on a single side in a side-changed manner by using the gradually increased jacking force so asto obtain a jacking force
